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 .
Also in 1978, Pluto's largest moon Charon was discovered; however, at the time Pluto was still considered to be one of the major planets. In 1993, the first asteroid moon was confirmed when the Galileo probe discovered the small Dactyl orbiting 243 Ida in the asteroid belt. The second was discovered around 45 Eugenia in 1998. [10]
The total mass of the asteroid belt is estimated to be 2.39 × 10 21 kg, which is just 3% of the mass of the Moon; the mass of the Kuiper Belt and Scattered Disk is over 100 times as large. [48] The four largest objects, Ceres, Vesta, Pallas, and Hygiea, account for maybe 62% of the belt's total mass, with 39% accounted for by Ceres alone.

In 1966, the Moon became the first Solar System body beyond Earth to be orbited by an artificial satellite , followed by Mars in 1971 , Venus in 1975 , Jupiter in 1995 , the asteroid Eros in 2000 (NEAR Shoemaker), Saturn in 2004 (Cassini–Huygens), and Mercury and Vesta in 2011 (MESSENGER and Dawn respectively).
"While more than 70,000 meteorites are known, only 6% had been clearly identified by their composition as coming from the moon, Mars, or Vesta, one of the largest asteroids in the main asteroid belt.
What is 2024 PT5, which will orbit Earth like a second moon? The asteroid 2024 PT5 was discovered by the NASA-funded Asteroid Terrestrial-impact Last Alert System (ATLAS) on Aug. 7, per USA TODAY.
Dactyl (/ ˈ d æ k t ɪ l / DAK-til; formally (243) Ida I Dactyl) is a small asteroid moon 1,200 by 1,400 by 1,600 m (3,900 by 4,600 by 5,200 ft), in size) that orbits 243 Ida, a main-belt asteroid. It was imaged by the Galileo spacecraft on August 28, 1993; Dactyl was discovered while examining the delayed image downloads from Galileo on ...
