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

  • Tiny fragment of a comet found inside a meteorite
    on April 15, 2019 at 3:00 pm

    A tiny piece of the building blocks from which comets formed has been discovered inside a primitive meteorite. The discovery by a Carnegie Institution of Science-led team, including a researcher now at Arizona State University, was published April 15 in Nature Astronomy. […]

  • Shadows on the Moon - a tale of ephemeral beauty,...
    on March 29, 2019 at 12:40 pm

    Between 1969 and 1972, a new type of archaeological site was created. For the first time, human bodies and the technology needed to sustain them altered the landscape of another world. The astronauts from the six Apollo missions left a suite of space-age artefacts behind on the lunar surface. And not only that: the missions brought to the moon new kinds of shadows, cast by machines and bodies and flags and rovers, in an interplay of movement and stillness. […]

  • Hubble watches spun-up asteroid coming apart
    on March 28, 2019 at 4:58 pm

    A small asteroid has been caught in the process of spinning so fast it's throwing off material, according to new data from NASA's Hubble Space Telescope and other observatories. […]

  • Why dangerous asteroids heading to Earth are so...
    on March 22, 2019 at 1:50 pm

    Earth is often in the firing line of fragments of asteroids and comets, most of which burn up tens of kilometres above our heads. But occasionally, something larger gets through. […]

    on March 19, 2019 at 6:04 pm

    A Southwest Research Institute-led team discovered evidence of abundant water-bearing minerals on the surface of the near-Earth asteroid (101955) Bennu. Using early spectral data from NASA's OSIRIS-REx spacecraft orbiting the asteroid, the team identified infrared properties similar to those in a type of meteorite called carbonaceous chondrites. […]
