The European Space Agency in January placed the asteroid's odds of hitting Earth at roughly 1%, before NASA's Jet Propulsion Laboratory estimated the risk was more like 1.6% at the tail end of the ...
When it came within less than 240,000 km (150,000 miles) of Earth, which is closer than the orbit of the Moon, the object sparked concerns that it might collide with the planet.
According to the latest calculations from NASA's Jet Propulsion Laboratory, there is a 1.6% chance the asteroid will strike Earth on December 22, 2032. The asteroid 2024 YR4 is now rated at Level ...
AstroForge relented after pushback from the astronomy community, acknowledging in January that it aimed to send the vehicle to an asteroid called 2022 OB5 — a relatively small space rock that ...
