Planet Nine is a hypothetical ninth planet in the outer region of the Solar System. [2] [4] Its gravitational effects could explain the peculiar clustering of orbits for a group of extreme trans-Neptunian objects (ETNOs), bodies beyond Neptune that orbit the Sun at distances averaging more than 250 times that of the Earth i.e. over 250 astronomical units (AU).
6.33 [2] Angular diameter. 0.23" to 0.071". 9 Metis is one of the larger main-belt asteroids. It is composed of silicates and metallic nickel - iron, and may be the core remnant of a large asteroid that was destroyed by an ancient collision. [9] Metis is estimated to contain just under half a percent of the total mass of the asteroid belt.
S l (S3OS2 -BB)[10] Absolute magnitude (H) 11.0 [1][3] 889 Erynia / ɛˈraɪniə / is a highly elongated background asteroid from the inner regions of the asteroid belt. It was discovered on 5 March 1918, by German astronomer Max Wolf at the Heidelberg-Königstuhl State Observatory, and given the provisional designations A918 EN and 1918 DG. [1]
Nonetheless, collisions between large asteroids occur and can produce an asteroid family, whose members have similar orbital characteristics and compositions. Individual asteroids within the belt are categorized by their spectra, with most falling into three basic groups: carbonaceous , silicate , and metal-rich .
For years, the existence of a missing Planet 9 has been one of the predominate theories attempting to explain some of the eccentric orbits found in the outer Solar System. But so far, no such ...
10 Hygiea is a major asteroid located in the main asteroid belt.With a mean diameter of between 425 and 440 km and a mass estimated to be 3% of the total mass of the belt, [11] it is the fourth-largest asteroid in the Solar System by both volume and mass, and is the largest of the C-type asteroids (dark asteroids with a carbonaceous surface) in classifications that use G type for 1 Ceres.
Solar System belts are asteroid and comet belts that orbit the Sun in the Solar System in interplanetary space. [1][2] 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 ...
Absolute magnitude (H) 4.4 [2][3] 2015 BP519, nicknamed Caju, [a] is an extreme trans-Neptunian object from the scattered disc on a highly eccentric and inclined orbit in the outermost region of the Solar System. [7] It was first observed on 17 January 2015, by astronomers with the Dark Energy Survey at Cerro Tololo Observatory (W84) in Chile ...
