Asteroid belt is a torus-shaped region in the Solar System, located roughly between the orbits of the planets Jupiter and Mars. It contains many solid, irregularly shaped bodies, of many sizes, but much smaller than planets, called asteroids or minor planets. It is also called the main asteroid belt to distinguish it from other asteroid populations in the Solar System such as near-Earth asteroids and trojan asteroids. About half its mass is contained in the four largest asteroids: Ceres, Vesta, Pallas, and Hygiea. The total mass of the asteroid belt is about 4% that of the Moon. Ceres, the only object in the asteroid belt large enough to be a dwarf planet, is about 950 km in diameter, whereas Vesta, Pallas, and Hygiea have mean diameters less than 600 km. The remaining bodies range down to the size of a dust particle. — Wikipedia

    NASA's Lucy spacecraft will add another asteroid encounter to its 4-billion-mile journey. On Nov. 1, 2023, the Southwest Research Institute-led Lucy mission will get a close-up view of a small main belt asteroid to conduct an engineering test of the spacecraft's innovative asteroid-tracking navigation system.

    In the coming years, NASA and the European Space Agency (ESA) will send two robotic missions to explore Jupiter's icy moon Europa. These are none other than NASA's Europa Clipper and the ESA's Jupiter Icy Moons Explorer (JUICE), which will launch in 2024, and 2023 (respectively). Once they arrive by the 2030s, they will study Europa's surface with a series of flybys to determine if its interior ocean could support life. These will be the first astrobiology missions to an icy moon in the outer […]

    The moon's pock-marked surface tells the story of its history. It's marked by over 9,000 impact craters, according to the International Astronomical Union (IAU.) The largest ones are called impact basins, not craters. Now, a new study published in The Astrophysical Journal Letters claims that asteroids didn't create the basins; leftover planetesimals did.

    Imagine walking into a room at night, turning out all the lights and closing the shades. Yet an eerie glow comes from the walls, ceiling, and floor. The faint light is barely enough to see your hands before your face, but it persists.
