LP 944-20 is a dim brown dwarf of spectral class M9 located 21 light-years from the Solar System in the constellation of Fornax.

A spectral type of M9 or later was assigned in this work and a distance of around 5 parsec was established thanks to the parallax being measured.

[10] In 1998 Tinney discovered that this M-dwarf shows the 6708 Å Lithium absorption line and H-alpha emission line, which helped to constrain the age to around 500 million years and established it as a brown dwarf with a mass of around 60 MJ.

[15][16] On 27 July 2000, radio emission (in flare and quiescence) was detected from this brown dwarf by a team of students at the Very Large Array.

The time series spectra show line profile distortions, which were interpreted as starspots.

[2] Observations with TESS found that LP 944-20 is variable with a period of around 3.8 hours and an amplitude of 1760±100 ppm.
