The Double Asteroid Redirection Test (DART) was a NASA space mission aimed at testing a method of planetary defense against near-Earth objects (NEOs). [4] [5] It was designed to assess how much a spacecraft impact deflects an asteroid through its transfer of momentum when hitting the asteroid head-on. [6]
"The dashboard displays the next five Earth approaches to within 4.6 million miles (7.5 million kilometers or 19.5 times the distance to the moon)," per NASA’s Asteroid Watch Dashboard.
The Psyche mission will arrive at the metallic asteroid — also known as an M-type asteroid, and it’s the largest in the solar system — in 2029 and study it in orbit for about two years.

The spacecraft dropped the sample capsule — containing an estimated 8.8 ounces of asteroid rocks and soil — from a distance of 63,000 miles (102,000 kilometers) above Earth’s surface early ...
This asteroid travels in both the main-belt and in the near-Earth region. It passed Earth on 29 June 2024 at a distance of 184,000 miles (295,000 kilometers). That distance is about 0.77 lunar distances (LD). [2] The close approach with Earth changed 2024 MK's orbit, shortening its orbital period by about 24 days.
An asteroid nearly the size of a football field now has roughly a 0.28% chance of hitting Earth in about eight years, NASA says — though at one point earlier its estimate reached as high as 3.1% ...
2024 UQ, designated formerly as A11dc6D, was a one-meter meteoroid that entered the Earth's atmosphere and burned up harmlessly on 22 October 2024 above the Pacific Ocean off the coast of California. 2024 UQ is the tenth impact event that was successfully predicted.
