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 below charts visualise the warning times of the close approaches listed in the above bargraph, by the size of the asteroid instead of by the year they occurred in. The sizes of the charts show the relative sizes of the asteroids to scale. This is based on the absolute magnitude of each asteroid, an approximate measure of size based on ...
A newly discovered asteroid named 2024 YR4 now has a 2.2% chance of affecting Earth in 2032 after recent observations. ... Automated asteroid warning systems sent out an alarm after determining ...
"An asteroid this size impacts Earth on average every few thousand years and could cause severe damage to a local region," the European Space Agency said. An asteroid could hit Earth in 2032, NASA ...
This list and the relevant databases do not consider impacts on Earth as close approaches. The impact of 2008 TC 3 was the first successfully predicted asteroid impact, while the impact of several small asteroids in Earth's atmosphere were observed visually or recorded by sensors designed to detect the detonation of nuclear devices as bolides.

It shows the effectiveness of asteroid warning systems at detecting close approaches. The sizes of the charts show the relative sizes of the asteroids to scale. For comparison, the approximate size of a person is also shown. This is based the absolute magnitude of each asteroid, an approximate measure of size based on brightness. [1]
