Luhman 16 A and Luhman 16 B are the closest brown dwarf stars to Earth, and the third-nearest star system to the Solar System. [e] SSSPM J0829-1309: 61,300 Red dwarf: An L2 dwarf that is fusing hydrogen. Similarly to 2MASS J0523-1403, SSSPM J0829-1309 is one of the least luminous and massive hydrogen-fusing stars, and is smaller than Jupiter ...
Parts-per-million chart of the relative mass distribution of the Solar System, each cubelet denoting 2 × 10 24 kg. This article includes a list of the most massive known objects of the Solar System and partial lists of smaller objects by observed mean radius. These lists can be sorted according to an object's radius and mass and, for the most ...
The smaller star, OGLE-TR-122B, is estimated to have a radius around 0.12 solar radii, or around 20% larger than Jupiter's, and a mass of around 0.1 solar masses, or approximately 100 times Jupiter's. This makes its average density approximately 50 times the Sun's [2] [3] or over 80 times the density of water.
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. 2021 PH27; Mercury. Mercury-crossing minor planets; Venus. Venus-crossing ...
It is a small, low-mass star, too faint to be seen with the naked eye, with an apparent magnitude of 11.13. Its Latin name means the 'nearest [star] of Centaurus'. Proxima Centauri is a member of the Alpha Centauri star system, being identified as component Alpha Centauri C, and is 2.18° to
Earth and space bound observatories observe Gliese 229 and its companion, which is perhaps 20–40 Jupiter masses in size [9] A substellar object may be a companion of a star, [9] such as an exoplanet or brown dwarf that is orbiting a star. [10] Objects as low as 8–23 Jupiter masses have been called substellar companions. [11]
To distinguish these groups, he called them "giant" and "dwarf" stars, [1] the dwarf stars being fainter and the giants being brighter than the Sun. Most stars are currently classified under the Morgan Keenan System using the letters O, B, A, F, G, K, and M, a sequence from the hottest: type O, to the coolest: type M.
TrES-2b (also known as Kepler-1b or GSC 03549-02811b) is an extrasolar planet orbiting the star GSC 03549-02811 located 750 light years away from the Solar System.The planet was identified in 2011 as the darkest known exoplanet, reflecting less than 1% of any light that hits it.
