    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 ...

    en.wikipedia.org/wiki/OGLE-TR-122

    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.

    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 ...

  5. Substellar object - Wikipedia

    en.wikipedia.org/wiki/Substellar_object

    Assuming that a substellar object has a composition similar to the Sun's and at least the mass of Jupiter (approximately 0.001 solar masses), its radius will be comparable to that of Jupiter (approximately 0.1 solar radii) regardless of the mass of the substellar object (brown dwarfs are less than 75 Jupiter masses).

  6. Compact object - Wikipedia

    en.wikipedia.org/wiki/Compact_object

    The usual endpoint of stellar evolution is the formation of a compact star.. All active stars will eventually come to a point in their evolution when the outward radiation pressure from the nuclear fusions in its interior can no longer resist the ever-present gravitational forces.

  7. Dwarf star - Wikipedia

    en.wikipedia.org/wiki/Dwarf_star

    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 .

  8. I don’t think a lot of people know that all four giant planets in our solar system have rings; Saturn’s are by far the most obvious, but Jupiter, Uranus, and Neptune own a set themselves.

  9. Kepler-37b - Wikipedia

    en.wikipedia.org/wiki/Kepler-37b

    The size of the star was obtained using asteroseismology; [7] Kepler-37 is currently the smallest star to be studied using this process. [6] This allowed the size of Kepler-37b to be determined "with extreme accuracy". [6] To date, Kepler-37b is the smallest planet discovered around a main-sequence star [b] outside the Solar System.
