Solar System Belts
Solar System belts are asteroid and comet belts that orbit the Sun in the Solar System in interplanetary space. The Solar System belts' size and placement are mostly a result of the Solar System having four giant planets: Jupiter, Saturn, Uranus and Neptune far from the sun. The 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. Formation The Solar System belts were formed in the formation and evolution of the Solar System. The Grand tack hypothesis is a model of the unique placement of the giant planets and the Solar System belts. Most giant planets found outside our Solar System, exoplanets, are inside the snow line, and are called Hot Jupiters. Thus in normal planetary systems giant planets form beyond snow line and then migrated towards the star. A small percent of giant planets migrate far from the star. In both types of migrations, the Solar System belts are lost in these planetary migrations. The G ...

Caltech
The California Institute of Technology (branded as Caltech) is a private university, private research university in Pasadena, California, United States. The university is responsible for many modern scientific advancements and is among a small group of Institute of Technology (United States), institutes of technology in the United States that are devoted to the instruction of pure and applied sciences. The institution was founded as a preparatory and vocational school by Amos G. Throop in 1891 and began attracting influential scientists such as George Ellery Hale, Arthur Amos Noyes, and Robert Andrews Millikan in the early 20th century. The vocational and preparatory schools were disbanded and spun off in 1910, and the college assumed its present name in 1920. In 1934, Caltech was elected to the Association of American Universities, and the antecedents of NASA's Jet Propulsion Laboratory, which Caltech continues to manage and operate, were established between 1936 and 1943 under ...

Kuiper Belt
The Kuiper belt ( ) is a circumstellar disc in the outer Solar System, extending from the orbit of Neptune at 30 astronomical units (AU) to approximately 50 AU from the Sun. It is similar to the asteroid belt, but is far larger—20 times as wide and 20–200 times as massive. Like the asteroid belt, it consists mainly of small Solar System body, small bodies or remnants from when the Formation and evolution of the Solar System, Solar System formed. While many asteroids are composed primarily of rock (geology), rock and metal, most Kuiper belt objects are composed largely of frozen Volatile (astrogeology), volatiles (termed "ices"), such as methane, ammonia, and water. The Kuiper belt is home to most of the objects that astronomers generally accept as dwarf planets: 90482 Orcus, Orcus, Pluto, Haumea, 50000 Quaoar, Quaoar, and Makemake. Some of the Solar System's natural satellite, moons, such as Neptune's Triton (moon), Triton and Saturn's Phoebe (moon), Phoebe, may ha ...

Hilda Asteroid
The Hilda asteroids (adj. ''Hildian'') are a List of minor-planet groups#Other groups out to the orbit of Jupiter, dynamical group of more than 6,000 asteroids located beyond the asteroid belt but within Jupiter's orbit, in a 3:2 orbital resonance with Jupiter. The namesake is the asteroid 153 Hilda. Hildas move in their elliptical orbits in such a fashion that they arrive closest to Jupiter's orbit (i.e. at their Apsis#Perihelion_and_aphelion, aphelion) just when either one of Jupiter's , or Lagrange points arrives there. On their next orbit their aphelion will synchronize with the next Lagrange point in the –– sequence. Since , and are 120° apart, by the time a Hilda completes an orbit, Jupiter will have completed 360° − 120° or two-thirds of its own orbit. A Hilda's orbit has a semi-major axis between 3.7 and 4.2 Astronomical unit, AU (the average over a long time span is 3.97), an eccentricity (orbit), eccentricity less than 0.3, and an inclination less ...
