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.
The asteroid and comet belts orbit the Sun from the inner rocky planets into outer parts of the Solar System, interstellar space. [ 16 ] [ 17 ] [ 18 ] An astronomical unit , or AU, is the distance from Earth to the Sun, which is approximately 150 billion meters (93 million miles). [ 19 ]
outer main-belt (a > 2.82 AU) A plot of inner solar system asteroids and planets as of 2006 May 9, in a manner that exposes the Kirkwood gaps. Similar to the position plot, planets (with trajectories) are orange, Jupiter being the outer most in this view. Various asteroid classes are colour coded: 'generic' main-belt asteroids are white.
5 Astraea (/ æ ˈ s t r iː ə /) is an asteroid in the asteroid belt. This object is orbiting the Sun at a distance of 385 million kilometres (2.5735 AU) with a period of 4.13 yr and an orbital eccentricity of 0.19. The orbital plane is inclined at an angle of 5.37° to the plane of the ecliptic. It is spinning with a period of 16.8 h.
28439 Miguelreyes (provisional designation 2000 AM 30) is a background asteroid from the central region of the asteroid belt, approximately 3.9 kilometers in diameter. The asteroid was discovered on 3 January 2000, by the LINEAR team at Lincoln Lab's ETS in Socorro, New Mexico, United States. [ 2 ]
6 Hebe (/ ˈ h iː b iː /) is a large main-belt asteroid, containing around 0.5% of the mass of the belt.However, due to its apparently high bulk density (greater than that of the Moon), Hebe does not rank among the top twenty asteroids by volume.
Schaber is a non-family asteroid from the main belt's background population. [4] It orbits the Sun in the outer asteroid belt at a distance of 2.4–3.8 AU once every 5 years and 7 months (2,026 days; semi-major axis of 3.13 AU). Its orbit has an eccentricity of 0.22 and an inclination of 12° with respect to the ecliptic. [2]
