Scientists have discovered a record-breaking asteroid: it rotates in 1.88 minutes.

According to ТСН: Researchers using data from the Vera Rubin Observatory have discovered an asteroid that rotates faster than any known objects larger than 500 meters.

The discovery of asteroid 2025 MN45

This cosmic object has been named 2025 MN45. Its diameter is approximately 710 meters, and it completes a full rotation around its axis in 1.88 minutes. The asteroid orbits the Sun in the asteroid belt.

Limits of rotational speed

In the asteroid belt, the limit of rotational speed at which an object can maintain integrity is 2.2 hours. The faster the asteroid rotates and the larger its size, the more resilient the material it is composed of must be.

Potential danger to Earth

The discovered fast-rotating asteroids mostly belong to near-Earth objects that pass within 50 million kilometers of Earth — this is a third of the distance between our planet and the Sun. Asteroids that are within 7.5 million kilometers of Earth are considered potentially hazardous to our planet.

We must not forget about the asteroid 2024 YR4, which was previously considered a threat to Earth, but now there is a possibility that it could target our moon. Scientists predict a possible impact on the Moon, the consequences of which could be catastrophic for humanity.

Research on asteroids like 2025 MN45 and 2024 YR4 is becoming increasingly relevant, as they may have serious consequences for Earth. Understanding their movement and properties will help scientists develop strategies to prevent possible collisions and their negative outcomes.
