The total mass of the asteroid belt is significantly less than Pluto's, and roughly twice that of Pluto's moon Charon. The asteroid belt is a torus-shaped region in the Solar System, centered on the Sun and roughly spanning the space between the orbits of the planets Jupiter and Mars.
Solar System belts are asteroid and comet belts that orbit the Sun in the Solar System in interplanetary space. [1] [2] The Solar System belts' size and placement are mostly a result of the Solar System having four giant planets: Jupiter, Saturn, Uranus and Neptune far from the sun. The giant planets must be in the correct place, not too close ...
The Kuiper belt is a great ring of debris similar to the asteroid belt, but consisting mainly of objects composed primarily of ice. [195] It extends between 30 and 50 AU from the Sun. It is composed mainly of small Solar System bodies, although the largest few are probably large enough to be dwarf planets. [196]
The total mass of the asteroid belt is estimated to be 2.39 × 10 21 kg, which is just 3% of the mass of the Moon; the mass of the Kuiper Belt and Scattered Disk is over 100 times as large. [48] The four largest objects, Ceres, Vesta, Pallas, and Hygiea, account for maybe 62% of the belt's total mass, with 39% accounted for by Ceres alone.
(248370) 2005 QN 173 is a main belt asteroid that undergoes recurrent comet-like activity near perihelion, [4] [5] and is now designated comet 433P/(248370) 2005 QN 173. [6] This object was discovered on 29 August 2005 by the Near-Earth Asteroid Tracking program at Palomar Observatory. [1]
Asteroid groups out to the orbit of Jupiter, showing eccentricity versus semi-major axis. Hungaria asteroids are the left-most dense grouping in blue. The core region of the asteroid belt is shown in red. Same as above, but showing inclination versus semi-major axis. Hungaria asteroids are the (top-)left-most dense grouping in blue.
The asteroid belt is a reservoir of small bodies in the Solar System located between the orbit of Mars and Jupiter. It is a source of interplanetary dust. Edgeworth-Kuiper belt, beyond the orbit of Neptune; Scattered disc, beyond the orbit of Neptune; Hills cloud; only the inner Oort cloud has a toroid-like shape. The outer Oort cloud is more ...
1234 Elyna / ɪ ˈ l aɪ n ə /, provisional designation 1931 UF, is an Eoan asteroid from the outer regions of the asteroid belt, approximately 25 kilometers in diameter.It was discovered on 18 October 1931, by astronomer Karl Reinmuth at the Heidelberg-Königstuhl State Observatory. [14]
