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
Anthony Cuthbertson,Graeme Massie and Vishwam Sankaran. February 2, 2023 at 8:18 PM. A green comet is flying past Earth for the first time in 50,000 years, offering skygazers a one-off opportunity ...
Proxima Centauri, the closest star to the Sun, at a distance of 4.2 ly(1.3 pc), is a red dwarf. A red dwarfis the smallest kind of staron the main sequence. Red dwarfs are by far the most common type of fusingstar in the Milky Way, at least in the neighborhood of the Sun. However, due to their low luminosity, individual red dwarfs cannot be ...
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.
Stellar classification. In astronomy, stellar classification is the classification of stars based on their spectral characteristics. Electromagnetic radiation from the star is analyzed by splitting it with a prism or diffraction grating into a spectrum exhibiting the rainbow of colors interspersed with spectral lines.
Pluto (minor-planet designation: 134340 Pluto) is a dwarf planet in the Kuiper belt, a ring of bodies beyond the orbit of Neptune. It is the ninth-largest and tenth-most-massive known object to directly orbit the Sun. It is the largest known trans-Neptunian object by volume, by a small margin, but is less massive than Eris.
