YR4 is between 40 and 90 meters in diameter, about the size of a large apartment block. The asteroid 2024 YR4, discovered in December last year, is moving towards Earth. A NASA expert has answered all the questions related to Asteroid 2024 YR4 that has been dominating headlines.

NASA has significantly lowered the risk of asteroid 2024 YR4 hitting Earth. Last week, the asteroid had a 3.1% probability of hitting Earth, which set a record level for large space rocks.

While the asteroid's possibly collision with earth wouldn't be until 2032, there's been a lot of talk about the possibility in recent weeks.

NASA has increased the chances of asteroid 2024 YR4 hitting Earth in 2032 to 1 in 32, or 3.1%, up from 1 in 42 as reported in previous calculations.

New observations of a small asteroid discovered in December have led astronomers to conclude that the chances of it striking Earth are almost zero, after earlier data had indicated a higher risk of a collision with this space rock about 40 to 90 metres wide.

Earth is no longer on a collision course with asteroid 2024 YR4, but it could potentially collide with the Moon. After weeks of observation, NASA and the European Space Agency confirmed that the asteroid no longer poses a threat to Earth.
