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 ...
Part of a symbiotic binary star system containing a red giant and a white dwarf. As in 2019, with mass 67.54 ± 12.79MJ (0.0523-0.0767 M☉) is the lowest known mass hydrogen-burning star. Luhman 16 B and Luhman 16 A are the closest brown dwarf stars to Earth, and the third-nearest star system to the Solar System.
Widely recognised as being among the largest known stars. [44] R Horologii: 635 [84] L/T eff: A red giant star with one of the largest ranges in brightness known of stars in the night sky visible to the unaided eye. Despite its large radius, it is less massive than the Sun. 119 Tauri (CE Tauri, Ruby Star) 587 – 593 [85] AD ρ Cassiopeiae
Astronomers classify it as a G-type main-sequence star. The largest objects that orbit the Sun are the eight planets. In order from the Sun, they are four terrestrial planets (Mercury, Venus, Earth and Mars); two gas giants (Jupiter and Saturn); and two ice giants (Uranus and Neptune). All terrestrial planets have solid surfaces.
A few notable large stars with masses less than 60 M☉ are shown in the table below for the purpose of comparison, ending with the Sun, which is very close, but would otherwise be too small to be included in the list. At present, all the listed stars are naked-eye visible and relatively nearby. Star name. Location.
The prograde satellites consist of the Himalia group and three others in groups of one. The retrograde moons are grouped into the Carme, Ananke and Pasiphae groups. Saturn has 146 moons with known orbits; 66 of them have received permanent designations, and 63 have been named. Most of them are quite small. Seven moons are large enough to be in ...
The following is a list of particularly notable actual or hypothetical stars that have their own articles in Wikipedia, but are not included in the lists above. BPM 37093 — a diamond star. Cygnus X-1 — X-ray source. EBLM J0555-57Ab — is one of the smallest stars ever discovered.
A star is a massive luminous spheroid astronomical object made of plasma that is held together by its own gravity.Stars exhibit great diversity in their properties (such as mass, volume, velocity, stage in stellar evolution, and distance from Earth) and some of the outliers are so disproportionate in comparison with the general population that they are considered extreme.
