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 ...
(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]
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.
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]
3015 Candy (prov. designation: 1980 VN) is a background asteroid from the outer regions of the asteroid belt, approximately 25 kilometers (16 miles) in diameter.It was discovered on 9 November 1980, by British-American astronomer Edward Bowell at Anderson Mesa Station in Flagstaff, Arizona. [13]
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.
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 ...
