MOSI monitoring asteroid that had record chance of colliding with Earth

Astronomers briefly raised the alert level for an asteroid that could be on a collision course with Earth. They gave it a 3% chance of hitting Earth in 2032, which is the highest percentage ever given for a near-Earth asteroid, but it has since been lowered to 1.5% probability. 

Odds of Asteroid 2024 YR4 hitting Earth go up again

Updates on Asteroid 2024 YR4 have been slower during the full Moon, but experts say the precision of the object’s orbit is getting better. In March, NASA’s James Webb Space Telescope will focus on the potential threat to Earth providing the best estimate of its size.
