Asteroid capture is an orbital insertion of an asteroid around a larger planetary body. When asteroids, small rocky bodies in space, are captured, they become natural satellites , [ 1 ] [ failed verification – see discussion ] specifically either an irregular moon if permanently captured, or a temporary satellite .
A NASA spacecraft brought samples from the asteroid Bennu back to Earth in 2023. The first in-depth analyses of that material have revealed organic molecules, including building blocks of life ...
The surface of the asteroid appears completely covered in ice. As this ice layer is sublimating, it may be getting replenished by a reservoir of ice under the surface. Organic compounds were also detected on the surface. [98] [99] [97] [100] The presence of ice on 24 Themis makes the initial theory plausible. [97]

These are Earth-originating examples of minerals found in Bennu samples from the US National Mineral Collection at the Smithsonian’s National Museum of Natural History: (foreground, from left ...
'Most dangerous asteroid' sample arrives in UK. Nasa's first look at 'beautiful' asteroid sample. This latest study adds to growing evidence that asteroids brought water and organic material to Earth.
A mission called OSIRIS-REx landed on an asteroid named Bennu in 2020, jammed its arm into the rock's surface, and scooped up a heaping sample of grit and dust. It was NASA's first-ever score of ...
Asteroid mining is the hypothetical extraction of materials from asteroids and other minor planets, including near-Earth objects. [1] Notable asteroid mining challenges include the high cost of spaceflight, unreliable identification of asteroids which are suitable for mining, and the challenges of extracting usable material in a space environment.
