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.
1992 – David Jewitt and Jane Luu of the University of Hawaii discover Albion, the first object deemed to be a member of the Kuiper belt. [216] 1993 – Asteroid Ida is visited by the Galileo before heading to Jupiter. Mission member Ann Harch discovers its natural satellite Dactyl in images returned by the spacecraft, the first asteroid moon ...
The inner Solar System's period of giant impacts probably played a role in Earth acquiring its current water content (~6 × 10 21 kg) from the early asteroid belt. Water is too volatile to have been present at Earth's formation and must have been subsequently delivered from outer, colder parts of the Solar System. [ 63 ]
Dinkinesh was discovered on 4 November 1999 by the Lincoln Near-Earth Asteroid Research (LINEAR) sky survey at Socorro, New Mexico. [2] The discovery observations were published by the Minor Planet Center (MPC) on 23 November 1999 and the asteroid was given the minor planet provisional designation 1999 VD 57, which describes its discovery year, month, and discovery order within the month.

The object is part of the Arjuna asteroid belt. Speaking to Space.com, Universidad Complutense de Madrid professor Carlos de la Fuente Marcos — one of the people who discovered the mini-moon ...
Jupiter might have shaped the Solar System on its grand tack. In planetary astronomy, the grand tack hypothesis proposes that Jupiter formed at a distance of 3.5 AU from the Sun, then migrated inward to 1.5 AU, before reversing course due to capturing Saturn in an orbital resonance, eventually halting near its current orbit at 5.2 AU.
Another 8% of the Earth meteorites can be traced to the Flora and Nysa asteroid families in the main asteroid belt, the research found. And about 6% of the meteorites can be traced to Vesta, it ...
The impactor likely formed in the outer solar system before migrating to the asteroid belt. A team of researchers think they know the origin of a massive space rock that hit Earth and killed off ...
