Moving at high velocity and on a well-tracked path, the asteroid will fly by at a comfortable distance. Events like these offer a reminder of space's unpredictable nature and the importance of ongoing sky surveillance. While 2025 MM poses no immediate threat, its flyby underscores the need for scientific vigilance in tracking objects that share our celestial neighbourhood.
Asteroid 2025 MM to make closest approach on July 01, 2025: Speed and distance
The asteroid is forecast to reach its nearest point to Earth on July 1, traveling at a distance of about 1.29 million kilometers (about 800,000 miles).
Although this is close in cosmic terms, it's over three times farther away from Earth than the Moon is.
Asteroid 2025 MM is traveling at a speed of approximately 23,874 miles per hour (38,428 kilometers per hour). Traveling this speed, it would take under two hours to orbit Earth if it were in a state of orbit. This is normal for near-Earth objects, which are drawn into the Sun's gravity and orbital dynamics as they move about the inner solar system.
Its high velocity and regular path made it simpler for space agencies to simulate its orbit and ensure that it would safely pass by our planet.
How large is asteroid 2025 MM
Asteroid 2025 MM is approximately 120 feet (36 meters) in diameter—similar to the wingspan of a Boeing 737 plane. While fairly small in cosmic perspective, it's large enough to be seriously considered by planetary defense specialists. Asteroids of this magnitude can do tremendous harm if they come into Earth's atmosphere or collide with the planet's surface.

Yet with 2025 MM, it will pass safely by, providing experts with an opportunity to observe it without risk.
Why Aten asteroids like 2025 MM are important to scientists
2025 MM is part of the Aten family of asteroids, which are known to have orbits that are generally within Earth's orbit around the Sun. The orbits of these asteroids normally cross Earth's orbit and hence are very significant to track. Though Aten asteroids are normally seen close to Earth, not all of them are hazardous.
NASA actually has a set of parameters by which they check if an asteroid is even likely to be hazardous.
Asteroid 2025 MM: Is it considered dangerous
NASA has confirmed that asteroid 2025 MM is not classified as a 'Potentially Hazardous Object' (PHO). According to NASA's Planetary Defense Coordination Office, an asteroid must be:
Larger than 150 meters (492 feet) in diameter, and
Come within 7.4 million kilometers (4.6 million miles) of Earth to qualify as potentially hazardous.
With its smaller size (120 feet) and more distant path, 2025 MM doesn't come anywhere close to either threshold. Yet it serves as a reminder that even small space rocks are worth closely monitoring, particularly since even minor changes in orbit could potentially present future hazards.
Why scientists are still keeping an eye on it
While 2025 MM will not strike Earth, scientists still track it using powerful telescopes and radar. This is owing to the fact that asteroid paths can alter over time as a result of numerous influences:
Solar radiation inducing slow drift (referred to as the Yarkovsky effect)
Collision or fragmentation occurrences within the asteroid belt
Even a small deviation in path would lead to an asteroid coming in closer in a subsequent orbit. That is why continuous monitoring and path forecasting models are essential in planetary defense operations.
Asteroid 2025 MM highlights the need for constant vigilance
While asteroid 2025 MM will pass safely by Earth, its visit is a sobering reminder of the dynamic and capricious nature of space. Our solar system is teeming with millions of asteroids and comets, several of which make their way across our planet's path without us even realizing it.
Asteroid 2025 MM poses no near-term threat, but it does underscore the absolute necessity of careful skygazing and scientific foresight. The heavens are full of marvels—and sometimes, possible threats—and being at the head of the curve may one day prove to be the difference between life and death.

Shukla In space: Benefits far outweigh cost, says Isro chief

The Rs 548 crore spent on the mission is a fraction of what India would have otherwise needed to spend on replicating the same training, exposure and systems-level experience, Isro chairman V Narayanan told TOI, in his first exclusive interview about the multinational commercial mission. Speaking from Houston, Narayanan said that the learning outcomes — spanning astronaut training (for two astronauts), mission operations, and hardware-software-human interface — cannot be measured purely in monetary terms. 'For a country of 140 crore people, what we've spent is only marginal,,' Narayanan said. For that, he said: 'We've gained access to infrastructure and experience that would otherwise require thousands of crores.' If one looks at the per capita cost on the Indian population, it adds up to around Rs 4 per head. Look Beyond Rupee Figure Narayanan, dismissing observations that Ax-4 is 'just a commercial mission', said discussions on such strategic missions must be rooted in long-term capability building rather than short-term financial arithmetic. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Morocco: New Container Houses (Prices May Surprise You) Container House | Search ads Search Now Undo 'For a programme like Gaganyaan , which spans Rs 20,000 crore including follow-on missions, these early investments are necessary. Training, confidence, exposure, systems understanding — these are foundational,' he said. He added that maturity in public discourse is essential. 'People must recognise that not all benefits can be quantified. But they can certainly be measured in preparedness and capability,' he said. Five Takeaways Narayanan identified five key areas where Ax-4 will directly strengthen India's human spaceflight capabilities: Training exposure, confidence building, operational experience, systems-and-process understanding, and cross-disciplinary learning. 'Our astronauts trained in world-class facilities simulating space conditions, including microgravity and life-support systems. Each hour of training they've undergone would cost crores if we were to replicate the infrastructure ourselves,' he said. He added that interacting with seasoned astronauts — including those who have flown to space multiple times or performed several spacewalks — helped boost the confidence of Indian crew members and mission teams. Astronauts — Shux and his backup Group Captain Prashant Nair — learnt how to function in space as a team, handle real-time challenges, and carry out experiments. He said working on and observing the mission to ISS has given India insights into module design, layout, onboard systems, and processes that will feed into future Gaganyaan and space station designs. 'We will, of course, have our own design and technology, but all this experience will help us develop those better,' he said. Isro Engineers Narayanan, who is leading efforts to ensure astronaut safety, said he has himself gained from observing operations in Houston. 'From data handling to high-level system safety discussions, our understanding of the end-to-end process has grown. This cannot be acquired by simulation or literature review alone,' he said. He added that the experience is equally valuable for backroom mission teams and decision-makers, who will now have real-world references to draw upon while preparing for Gaganyaan. TOI had reported last week about some specifics the Isro team is learning back in Houston, where mission control for Ax-4 is. Space Station India plans to build its own space station after the Gaganyaan crewed flights. Narayanan said direct exposure to the ISS environment will inform the design, configuration, and operational planning of the proposed Indian facility. 'We had only studied the ISS on paper. Now we are seeing it in action. We may not adopt the same model, but this will help us make informed design choices,' he said.

Anil Menon: Who Is NASA Astronaut Whose Wife Went On Private Spacewalk Mission In 2024?
Last Updated: NASA said it is sending Anil Menon for his first mission to the International Space Station as a flight engineer and Expedition 75 crew member in June 2026 Selected to be an astronaut in 2021, Anil Menon will make his first trip to space as a flight engineer and Expedition 75 crew member in June 2026. NASA said it is sending Menon for his first mission to the International Space Station next year, and he will be launching aboard the Roscosmos Soyuz MS-29 spacecraft with cosmonauts Pyotr Dubrov and Anna Kikina. The premier space agency said after launching from the Baikonur Cosmodrome in Kazakhstan, the trio will spend approximately eight months aboard the orbiting laboratory. Anil Menon, who is a NASA Artemis astronaut candidate graduate, will conduct scientific investigations and technology demonstrations to help prepare humans for future space missions. Fun fact: his wife Anna Menon, who worked for NASA before joining SpaceX, went for a private spacewalk mission last year. She is a lead space operations engineer at Elon Musk's company and has written a children's book about space titled Kisses from Space. Like his wife, he has also worked for SpaceX, serving as the first flight surgeon while helping to launch the first crewed Dragon spacecraft on NASA's SpaceX Demo-2 mission and building SpaceX's medical organisation to support humans on future missions. He served as a crew flight surgeon for both SpaceX flights and NASA expeditions aboard the space station. Menon graduated with the 23rd astronaut class in 2024. He began preparing for his first space station flight assignment after completing initial astronaut candidate training. He still practises emergency medicine at Memorial Hermann's Texas Medical Center and teaches residents at the University of Texas residency programme in his spare time. First Published:

Major reports about how climate change affects the US are removed from websites
WASHINGTON: Legally mandated US national climate assessments seem to have disappeared from the federal websites built to display them, making it harder for state and local governments and the public to learn what to expect in their backyards from a warming world. Scientists said the peer-reviewed authoritative reports save money and lives. Websites for the national assessments and the US Global Change Research Program were down Monday and Tuesday with no links, notes or referrals elsewhere. The White House, which was responsible for the assessments, said the information will be housed within NASA to comply with the law, but gave no further details. Searches for the assessments on NASA websites did not turn them up. NASA did not respond to requests for information. The National Oceanic and Atmospheric Administration, which coordinated the information in the assessments, did not respond to repeated inquiries. "It's critical for decision makers across the country to know what the science in the National Climate Assessment is. That is the most reliable and well-reviewed source of information about climate that exists for the United States," said University of Arizona climate scientist Kathy Jacobs, who coordinated the 2014 version of the report. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Glicemia acima de 100? Insira essa fruta na sua dieta Saúde Nacional Undo "It's a sad day for the United States if it is true that the National Climate Assessment is no longer available," Jacobs said. "This is evidence of serious tampering with the facts and with people's access to information, and it actually may increase the risk of people being harmed by climate-related impacts." Harvard climate scientist John Holdren, who was President Obama's science advisor and whose office directed the assessments, said after the 2014 edition he visited governors, mayors and other local officials who told him how useful the 841-page report was. It helped them decide whether to raise roads, build seawalls and even move hospital generators from basements to roofs, he said. "This is a government resource paid for by the taxpayer to provide the information that really is the primary source of information for any city, state or federal agency who's trying to prepare for the impacts of a changing climate," said Texas Tech climate scientist Katharine Hayhoe, who has been a volunteer author for several editions of the report. Copies of past reports are still squirreled away in NOAA's library. NASA's open science data repository includes dead links to the assessment site. The most recent report, issued in 2023, included an interactive atlas that zoomed down to the county level. It found that climate change is affecting people's security, health and livelihoods in every corner of the country in different ways, with minority and Native American communities often disproportionately at risk. The 1990 Global Change Research Act requires a national climate assessment every four years and directs the president to establish an interagency United States Global Change Research Program. In the spring, the Trump administration told the volunteer authors of the next climate assessment that their services weren't needed and ended the contract with the private firm that helps coordinate the website and report. Additionally, NOAA's main website was recently forwarded to a different NOAA website. Social media and blogs at NOAA and NASA about climate impacts for the general public were cut or eliminated. "It's part of a horrifying big picture," Holdren said. "It's just an appalling whole demolition of science infrastructure." The national assessments are more useful than international climate reports put out by the United Nations every seven or so years because they are more localized and more detailed, Hayhoe and Jacobs said. The national reports are not only peer reviewed by other scientists, but examined for accuracy by the National Academy of Sciences, federal agencies, the staff and the public. Hiding the reports would be censoring science, Jacobs said. And it's dangerous for the country, Hayhoe said, comparing it to steering a car on a curving road by only looking through the rearview mirror: "And now, more than ever, we need to be looking ahead to do everything it takes to make it around that curve safely. It's like our windshield's being painted over."
