Solar System belts are asteroid and comet belts that orbit the Sun in the Solar System in interplanetary space.[1][2] The Solar System as both major and minor asteroid and comet belts in the inner Solar System. The Solar System is unique in that it has multiple belts. The observation of other planetary systems has found these systems to have no asteroid belts or one vast asteroid belt. The stars Fomalhaut, HD 69830 and Epsilon Eridani are examples of systems with one large asteroid belt. [3][4][5] The Solar System belts size and placement are mostly a result of the Solar System having four gas giant planets: Jupiter, Saturn, Uranus and Neptune far from the sun. The gas giant planets must be in the correct place, not too close or too far from the sun for a system to have Solar System belts. [6][7] [8]
Formation
The Solar System belts were formed in the formation and evolution of the Solar System.[9] The Grand tack hypothesis is the theory of the unique placement of the gas giants and the Solar System belts.[6][7][10] Most gas giant planets found outside our Solar System, exoplanets, are inside the snow line, and are called Hot Jupiters. [8][11] Thus in normal planetary systems gas giants form beyond snow line and then migrated towards the star. A small percent of gas giants migrate far from the star. In both types of migrations, the Solar System belts are lost in these planetary migrations. The Grand tack hypothesis explains how in the Solar System gas giants migrated in unique way to form the Solar System belts and near circular orbit of planets around the Sun. [11] The Solar System's belts are one key parameters for a Solar System that can support complex life, as circular orbits are a parameter needed for the Habitable zone for complex life. [12][13] [14][15]
Solar System belts
The asteroid and comet belts orbit the Sun from the inner rocky planets into outer parts of the Solar System, interstellar space.[16][17][18] An astronomical unit, or AU, is the distance from Earth to the Sun, which is approximately 150 billion meters (93 million miles).[19] Small Solar System objects are classified by their orbits:[20][21]
- Apollo asteroids, small group of Near-Earth objects, .5 to 1.017 AU
- Amor asteroids, small group of Near-Earth objects, 1.017 AU to 1.3 AU
- Mars trojans small group around Mars orbit 1.3 to 1.6 AU
- Hungaria asteroids, small group, 1.78 to 2.00 AU
- Main Asteroid belt (main belt), between Mars and Jupiter, in near circular orbit, 2.2 and 3.2 AU
- Alinda asteroids, small group, 2.5 AU in elliptical orbits
- Hilda asteroid small group just inside Jupiter, 4.0 AU
- Jupiter trojan (Greeks asteroid) small group near Jupiter's orbit, 5.05 to 5.35 AU
- Centaur belt icy planetoids, between Jupiter and Neptune, 5.2 to 30.1 AU
- Scattered belt small group, 21.5 to 215 AU
- Kuiper belt large belt, 43 to 64.5 AU
- Trans-Neptunian object >30 AU
- Sednoid (inner Oort cloud objects) small group of four or more, high elliptical orbits, 47.8 to 80 AU
- Oort cloud a large belt, 107.5 to 2,1505 AU (interstellar space)
Planets
Solar System planets and dwarf planets listed for distances comparison to belts. The Solar System planets are all in near circular orbit. [22]
Planets:
- Mercury 0.39 AU
- Venus 0.72 AU
- Earth 1 AU
- Mars 1.52 AU
- Jupiter 5.2 AU
- Saturn 9.54 AU
- Uranus 19.2 AU
- Neptune 30.06 AU
Dwarf planets:
Dwarf planets, other than Ceres, are plutoids that have elliptical orbits:[23]
- Ceres, 2.8 AU in the asteroid belt
- Orcus 39.4 AU, Trans-Neptunian-Kuiper belt object
- Pluto 39 AU, Kuiper belt
- 120347 Salacia 42 AU, Trans-Neptunian-Kuiper belt object
- Haumea 43 AU, Kuiper belt
- Makemake 45.8 AU, Kuiper belt
- Eris 95.6 AU, Kuiper belt
- Gonggong Scattered disc object, 34 to 101 AU
- Quaoar Kuiper belt object, 41.9 to 45.4 AU
- Sedna 76 to 506 AU
