Currently most of the objects of mass between 10 9 kg to 10 12 kg (less than 1000 teragrams (Tg)) listed here are near-Earth asteroids (NEAs). The Aten asteroid 1994 WR12 has less mass than the Great Pyramid of Giza, 5.9 × 10 9 kg. For more about very small objects in the Solar System, see meteoroid, micrometeoroid, cosmic dust, and ...
This list is designed to include all planets that are larger than 1.7 times the size of the largest planet in the Solar System, Jupiter. Some well-known planets that are smaller than 1.7 R J ( 19.055 R đ¨ or 121 536 .4 km ) have been included for the sake of comparison.
A dwarf planet is a small planetary-mass object that is in direct orbit around the Sun, massive enough to be gravitationally rounded, but insufficient to achieve orbital dominance like the eight classical planets of the Solar System. The prototypical dwarf planet is Pluto, which for decades was regarded as a planet before the "dwarf" concept ...
The inner Solar System is the region comprising the terrestrial planets and the asteroids. [ 89 ] Composed mainly of silicates and metals, [ 90 ] the objects of the inner Solar System are relatively close to the Sun; the radius of this entire region is less than the distance between the orbits of Jupiter and Saturn.
The following is a list of Solar System objects by orbit, ordered by increasing distance from the Sun. Most named objects in this list have a diameter of 500 km or more. The Sun, a spectral class G2V main-sequence star. The inner Solar System and the terrestrial planets. Mercury. Mercury-crossing minor planets. Venus. Venus-crossing minor planets.
Excluded objects [ edit ] Kepler-37e is listed with a radius of 0.37 ± 0.18 R đ¨ in the Exoplanet Archive based on KOI data, but the existence of this planet is doubtful, [ 19 ] and assuming its existence, a 2023 study found a mass of 8.1 ± 1.7 M đ¨ , inconsistent with such a small radius.
Contents. Mercury (planet) Surface temp. Mercury is the first planet from the Sun and the smallest in the Solar System. In English, it is named after the ancient Roman god Mercurius (Mercury), god of commerce and communication, and the messenger of the gods. Mercury is classified as a terrestrial planet, with roughly the same surface gravity as ...
Kepler-37b. Kepler-37b is a sub-Earth, an exoplanet with a radius and mass smaller than Earth. Its equilibrium temperature is 718 K (445 °C; 833 °F). [2] Because of its small size, it is not expected to have an atmosphere. [6] Its radius is approximately 0.31 Rđ¨ (about 1,980 kilometres (1,230 mi)), [2] slightly larger than the Moon [7] (0. ...
