Asteroids don’t just slam into planets like Jupiter or Earth, they also collide with each other. Astronomers using Hubble witnessed one such impact in the asteroid belt, an area between Mars and Jupiter that holds the rubble leftover from the construction of our solar system.
Shown below is the distribution of asteroids in semimajor axis, eccentricity space contained in the inner solar system. Major groups are shown in the labeled boxes and include the Hungaria, Cybele, Hilda, and Trojan Groups. Also shown are the main-belt zones and the Flora family.
In this work, we reexamine the architecture of the asteroid belt by determining the bias-corrected distribution of 99.99% of its mass based on compositional information provided by ground-based and space-based measurements.
This animation represents a map of the increased count of all known asteroids in the solar system between Jan. 1, 1999, and Jan. 31, 2018. Blue represents near-Earth asteroids. Orange represents main-belt asteroids between the orbits of Mars and Jupiter.
29 Ιαν 2014 · The structure of the main belt is divided by unstable regions, seen most prominently at 2.5 au and 2.8 au (locations where an asteroid’s orbit is ‘in resonance’ with Jupiter’s orbit), that...
15 Ιουν 2015 · Asteroid mass is grouped according to objects within four size ranges, with diameters of 100–1,000 km, 50–100 km, 20–50 km and 5–20 km. Seven zones are defined as in Fig. 1: Hungaria, inner...
30 Ιουν 2021 · Most of this ancient space rubble can be found orbiting our Sun between Mars and Jupiter within the main asteroid belt. Asteroids range in size from Vesta – the largest at about 329 miles (530 kilometers) in diameter – to bodies that are less than 33 feet (10 meters) across.
