The asteroids in the inner solar system are hard to see, but a specialized camera can spot them briefly each night. These rocks are NOT expected to intersect with us.
Earth has a new “mini-moon” after an asteroid has joined our orbit.. The object, known as 2024 PT5, has been chasing after us for years. Now, it has become close enough to be pulled in by our ...
A newly discovered asteroid named 2024 YR4 now has a 2.2% chance of affecting Earth in 2032 after recent observations.
This is a list of asteroids that have impacted Earth after discovery and orbit calculation that predicted the impact in advance. As of December 2024, all of the asteroids with predicted impacts were under 5 m (16 ft) in size that were discovered just hours before impact, and burned up in the atmosphere as meteors.
The full ATLAS concept consists of eight telescopes, spread over the globe for 24h/24h coverage of the full night sky. As long as their radiant is not too close to the Sun, the automated system provides a one-week warning for a 45 metres (150 ft) diameter asteroid, and a three-week warning for a 120 m (390 ft) one.

During 2022 about 124 asteroids passed within 1 LD of Earth. As most asteroids passing within a lunar distance are less than 40 meters in diameter, they generally are not detected until they are within several million km of Earth. For reference, the radius of Earth is about 0.0000426 AU (6,370 km; 3,960 mi) or 0.0166 lunar distances.
An asteroid first spotted in December has a 1.2% chance of hitting Earth in 2032. Scientists are tracking the space rock to learn more about its size and trajectory.
As sky surveys improve, smaller and smaller asteroids are regularly being discovered. Scientists estimate that several dozen asteroids in the 6–12 m (20–39 ft) size range fly by Earth at a distance closer than the moon every year , but only a fraction of these are actually detected.
