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 .
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]
OSIRIS-REx performed closer passes of the Bennu surface, initially at about 6.5 km (4.0 mi) through December to further refine the shape and orbit of Bennu. Preliminary spectroscopic surveys of the asteroid's surface by the OSIRIS-REx spacecraft detected the presence of hydrated minerals in the form of clay. While researchers suspect that Bennu ...
On Sunday, NASA’s OSIRIS-Rex mission will deliver a sample it collected from asteroid Bennu, completing a seven-year journey that could provide insights into how life originated on Earth.
Surface of asteroid 433 Eros. Regolith (/ ˈ r ɛ ɡ ə l ɪ θ /) [1] [2] is a blanket of unconsolidated, loose, heterogeneous superficial deposits covering solid rock. It includes dust, broken rocks, and other related materials and is present on Earth, the Moon, Mars, some asteroids, and other terrestrial planets and moons. [3]

Jupiter is the most massive planet in the Solar System, and because of its large mass it has a vast sphere of gravitational influence, the region of space where an asteroid capture can take place under favorable conditions. [126] Jupiter is able to capture comets in orbit around the Sun with a certain frequency. In general, these comets travel ...
Nasa has issued an alert for a stadium-sized asteroid set to make a close approach to Earth on Tuesday.. The 2024 ON asteroid measures 290 metres (950 feet) across and will come within 1 million ...
