Near-Earth Asteroids as of April 2024

April 2024

Infographic for Planetary Defense by the numbers. The title reads Near-Earth Asteroids next to the NASA logo. 34,603 discovered near-earth asteroids of all sizes. 861 discovered and 50 estimated left to be found asteroids larger than 1 km. 10,832 discovered and 15,000 estimated left to be found asteroids larger than 140 meters. Five years until asteroid Apophis makes its close approach to Earth. 6 known near-Earth asteroids passed closer to Earth than the moon in the last 30 days, 116 in the last 365 days and 442,200,000 observations submitted to the Minor Planet Center.

Each month, NASA’s Planetary Defense Coordination Office releases a monthly update featuring the most recent figures on NASA’s planetary defense efforts, near-Earth object close approaches, and other timely facts about comets and asteroids that could pose an impact hazard with Earth. Here is what we've found for April 2024.
