YR4 has a 2% chance of hitting Earth in 2032. Astronomers are tracking it to refine estimates of its size and orbit to see how much of a risk the space rock poses.

Over the next several weeks, astronomers will be looking closely at an asteroid called 2024 YR4 that could be as big as a football field as they try to determine how likely it is to strike Earth in 2032.

Scientists say the threat of a newly discovered asteroid has risen slightly in the past few weeks, as the world's telescopes rush to track its course.
