J002E3 is an object in space which is thought to be the S-IVB third stage of the Apollo 12 Saturn V rocket. It was discovered on September 3, 2002, by amateur astronomer Bill Yeung . Initially thought to be an asteroid , it has since been tentatively identified as the third stage of Apollo 12 Saturn V based on spectrographic evidence consistent ...
The head of planetary defense at the European Space Agency discusses 2024 YR4, an asteroid with a small chance of striking Earth eight years from now. Key facts about asteroid that could hit Earth ...
2024 YR 4 is an asteroid estimated to be 40 to 90 metres (130 to 300 ft) in diameter that is classified as an Apollo-type (Earth-crossing) near-Earth object.It was discovered by the Chilean station of the Asteroid Terrestrial-impact Last Alert System (ATLAS) on 27 December 2024.
Among the numbered minor planets with an unambiguous period solution are (459872) 2014 EK 24, a 60-meter sized stony NEO with a period of 352 seconds, as well as (335433) 2005 UW 163 and (60716) 2000 GD 65, two main-belt asteroids, with a diameter of 0.86 and 2.25 kilometers and a period of 1.29 and 1.95 hours, respectively (see full list).
Asteroid 2024 YR4 also rates 3 of 10 on the Torino Impact Hazard Scale, a method for astronomers to categorize and rate the threat of near-Earth objects. For those reasons, the asteroid is one ...
Dubbed 2024 YR4, the asteroid was first spotted on December 27, 2024, by the El Sauce Observatory in Chile. Based on its brightness, astronomers estimate it is between 130 and 300 feet wide.
A newly discovered asteroid named 2024 YR4 now has a 2.2% chance of affecting Earth in 2032 after recent observations.
The object was on a temporary satellite orbit around Earth, leaving for a solar orbit in June 2003. Calculations showed that it was also on a solar orbit before 2002, but was close to Earth in 1971. J002E3 was identified as the third stage of the Saturn V rocket that carried Apollo 12 to the Moon.
