This is a label given to space rocks larger than about 150m, whose orbits around the sun bring them within about 48 million km (30 million miles) of Earth. Next four asteroids approaching Earth (Nasa)
A newly discovered asteroid named 2024 YR4 now has a 2.2% chance of affecting Earth in 2032 after recent observations.
The chances of asteroid 2024 YR4 colliding with Earth in 2032 hit a record high. Experts expect the risk percentage to fluctuate before likely dropping to zero. Here’s why.
The asteroid's provisional designation as a minor planet, "2024 YR 4", was assigned by the Minor Planet Center when its discovery was announced on 27 December 2024. [2] The first letter, "Y", indicates that the asteroid was discovered in the second half-month of December (16 to 31 December), and "R 4" indicates that it was the 117th provisional designation to be assigned in that half-month.
