Asteroid belt is the circumstellar disc in the Solar System located roughly between the orbits of the planets Mars and Jupiter. It is occupied by numerous irregularly shaped bodies called asteroids or minor planets. The asteroid belt is also termed the main asteroid belt or main belt to distinguish it from other asteroid populations in the Solar System such as near-Earth asteroids and trojan asteroids. About half the mass of the belt is contained in the four largest asteroids: Ceres, Vesta, Pallas, and Hygiea. The total mass of the asteroid belt is approximately 4% that of the Moon, or 22% that of Pluto, and roughly twice that of Pluto’s moon Charon (whose diameter is 1200 km). — Wikipedia

  • Newfound kilometer-size asteroid orbits the sun...
    on July 9, 2019 at 2:05 pm

    Astronomers have spotted an unusual asteroid with the shortest "year" known for any asteroid. The rocky body, dubbed 2019 LF6, is about a kilometer in size and circles the sun roughly every 151 days. In its orbit, the asteroid swings out beyond Venus and, at times, comes closer in than Mercury, which circles the sun every 88 days. 2019 LF6 is one of only 20 known "Atira" asteroids, whose orbits fall entirely within Earth's.

    The asteroid belt between Mars and Jupiter preserves the processes of planetary formation, frozen in time. Vesta, the second largest asteroid in this belt, provides an outstanding opportunity for scientists to investigate the origin and formation of planets. In particular, Vesta has kept its crust, mantle and metallic core, much like Earth. Careful mapping of Vesta by NASA's Dawn mission showed that the crust at the south pole of Vesta is unusually thick. […]

    on July 2, 2019 at 1:31 pm

    A team of researchers affiliated with several institutions in Spain has found evidence that suggests the dwarf planet Ceres is experiencing wrinkling on its surface. In their paper published in the journal Nature Astronomy, the group explains their study of data from the Dawn spacecraft and what it revealed. […]
