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 ...
The largest of these may have a hydrostatic-equilibrium shape, but most are irregular. Most of the trans-Neptunian objects (TNOs) listed with a radius smaller than 200 km have "assumed sizes based on a generic albedo of 0.09" since they are too far away to
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.
Two teams of scientists have discovered a theoretically habitable planet called Gliese 12b that’s smaller than Earth but bigger than Venus, just 40 light-years away.
The three other potential planets orbiting Barnard's star all apparently are rocky and smaller than Earth, ranging from 20-30% of Earth's mass. The hope is that at least one of these may be in the ...
Proxima Centauri is the nearest star to Earth after the Sun, located 4.25 light-years away in the southern constellation of Centaurus. This object was discovered in 1915 by Robert Innes. 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'.
The Hertzsprung–Russell diagram showing the location of main sequence dwarf stars and white dwarfs. A dwarf star is a star of relatively small size and low luminosity. Most main sequence stars are dwarf stars. The meaning of the word "dwarf" was later extended to some star-sized objects that are not stars, and compact stellar remnants that ...
Our Milky Way galaxy's most common type of star is called a red dwarf - much smaller and less luminous than our sun. But the discovery of a planet at least 13 times Earth's mass orbiting very ...
