The risk of a huge asteroid hitting Earth has dropped after Nasa reported its highest-ever impact probability for an object of its size.
Space rock 2024 YR4, estimated to be 130 to 300 feet wide (40 to 100 metres), now has a 1.5% chance of colliding with Earth in December 2032, the agency said.
On Tuesday, Nasa put the impact probability at 3.1%, the highest ever recorded for an object of its size.
New observations of asteroid 2024 YR4 helped us update its chance of impact in 2032. The current probability is 1.5%.

Our understanding of the asteroid's path improves with every observation. We'll keep you posted. https://t.co/LuRwg1eaCv pic.twitter.com/SfZIxflB95
It is too soon to know where it might land if it did hit Earth.
Experts expect the probability of collision will change as more observations are made.
There is a 0.8% chance the asteroid will impact the moon, Nasa said.
The asteroid was first spotted in December by a telescope in Chile.
