A newly detected asteroid, named 2024 YR4, has been observed by NASA scientists, carrying a 1.2 percent probability of colliding with Earth on December 22, 2032. The asteroid, estimated to be around 55 metres in diameter, has been tracked since its discovery on December 27, 2024, through the Asteroid Terrestrial-impact Last Alert System. While the likelihood of impact remains low, experts indicate that if the object were to strike Earth, it could generate an explosion equivalent to eight megatons of TNT—over 500 times the power of the Hiroshima bomb—posing a serious threat to urban areas. Several close approaches to Earth have been predicted over the next 50 years, with the most significant occurring in 2032.

Probability and Potential Consequences

According to data from NASA, 2024 YR4 has been categorised as a Level 3 threat on the Torino Impact Hazard Scale. This classification is assigned to space objects that warrant public and scientific attention due to their potential for impact within the next century. Most asteroids of this level, however, are eventually downgraded as additional observations refine their trajectories. While this asteroid is not large enough to cause a global catastrophe, a direct collision with a densely populated region could lead to significant destruction and loss of life. Scientists stress the importance of continuous monitoring and updated risk assessments.

Future Close Approaches and Monitoring Efforts

Reports indicate that 2024 YR4 will pass Earth several times between 2028 and 2074, with the highest impact probability currently projected for December 2032. NASA and other space agencies continue to develop asteroid deflection technologies, including kinetic impactor missions such as the Double Asteroid Redirection Test (DART), which successfully demonstrated the ability to alter an asteroid’s trajectory. Although the probability of collision remains low, experts assert that sustained tracking and preparedness measures are essential in mitigating potential asteroid threats in the future.

Russian Kosmos Satellites Release Mysterious Object in Orbit

A group of Russian satellites launched earlier this year has caught the attention of space watchers around the world. The satellites – Kosmos 2581, 2582, and 2583 – were sent into orbit in early February from the Plesetsk Cosmodrome. They’ve been placed in a near-polar orbit, about 585 kilometres above Earth. So far, Russian officials haven’t confirmed what these satellites are actually meant to do. But what’s really stirred interest is the release of an unknown object from one of them. This new development, spotted in mid-March, has prompted fresh scrutiny from space monitoring teams across the globe.

What We Know So Far

According to tracking data from the United States Space Force and other monitoring groups, the mysterious object appeared on March 18. It was quickly catalogued and, at first, linked to Kosmos 2581. Later on, though, some signals hinted it might be tied to Kosmos 2583 instead. What’s clear is that the object was released while the satellites were still active – and so far, Russia hasn’t said a word about it.

Interestingly, before the object showed up, the satellites were seen carrying out what’s known as “proximity operations” – basically manoeuvring close to other objects in orbit, which is not something routine satellites typically do.

Expert Insight and Possible Explanations

Astrophysicist Jonathan McDowell from the Harvard-Smithsonian Center for Astrophysics spoke to Space.com about the situation. He pointed out that the satellites had been making deliberate close-range movements, which has led many to believe this isn’t just routine activity.

As for the object itself, there are a few possibilities. It could be part of a satellite testing programme or a tool for formation flying. There’s also a chance it’s linked to some kind of military experiment. While a technical malfunction hasn’t been ruled out, experts note that accidents like that usually leave behind several bits of debris – and that doesn’t seem to be the case here.

Putting It Into Context

The “Kosmos” label has been used by Russia for decades, dating back to 1962. It covers a broad range of secretive military and scientific missions. Triplets like this group aren’t unusual either – China and the US have also used similar formations, often for surveillance or intelligence-gathering purposes.
Still, the exact purpose of Kosmos 2581, 2582, 2583 – and now this newly released object – remains a mystery. Until more information is released (if it ever is), analysts will continue to watch closely from the ground.

NASA’s Parker Solar Probe Completes Second Close Flyby of the Sun

NASA’s Parker Solar Probe has made its second close flyby of the sun. The spacecraft travelled at a speed of 692000 kilometres per hour. It moved within 6.1 million kilometres of the sun. This event took place on March 22. A signal confirming its good health was received on March 25. The signal confirmed that all systems on board were working as planned. The probe was designed to study solar winds and collect data from the sun’s outer atmosphere. The mission is being used to help scientists understand solar activity that affects Earth.

More About The Mission

According to NASA’s announcement, the probe’s instruments were activated during the pass. They were used to study the corona. This is the outer layer of the sun’s atmosphere. The spacecraft was operated on its own during the flyby. It had been programmed in advance. Scientists believe this data may help them understand why the corona is hotter than the sun’s surface. The data is also being used to study changes in space weather. This information is considered important for protecting satellites and communication systems on Earth.

Quote from NASA

In a press release issued by NASA, acting Administrator Janet Petro said that the mission has entered a zone no spacecraft has visited before. Petro said this while addressing the media at the agency’s Washington headquarters. She said that the research is expected to change how solar science is studied in the future.

Award given to the team

As per a statement released by the National Aeronautic Association, the mission team was given the 2024 Robert J. Collier Trophy. The team includes experts from NASA and Johns Hopkins Applied Physics Laboratory. Ralph Semmel, Director at Johns Hopkins APL, said that the mission was once believed to be impossible. He shared this in an interview with NASA’s press team. The next close flyby is expected to take place on June 19.
