Headlines:

NASA officials this week said recent calculations show a significantly smaller risk than previously believed that Earth could be annihilated in 2032 as a result of being hit by Asteroid 2024 YR4. The moon, however, may not be in the clear. 

When first discovered in December, Asteroid 2024 YR4 had a small but notable chance of impacting Earth in 2032, according to information from NASA's Planetary Defense Department. That chance rose above 1% and then 3% before recent NASA calculations now estimate the likelihood of it impacting Earth at 0.004%.

Here's why this asteroid made headlines, how it could impact the moon and how a big addition in 2027 could change how scientists study space objects. 

MARCH BLOOD MOON: Total lunar eclipse will result in a blood moon in March. Here's when to see it.

The asteroid 2024 YR4 was discovered Dec. 27, 2024 in Chile through the NASA-funded Asteroid Terrestrial-impact Last Alert System (ATLAS).

The size is estimated to be 130 to 300 feet across according to NASA, but Johnson said there is still some uncertainty to the size due to the amount of light it reflects.
