Distance

The first parallax measurement from 1996 found that LP 944-20 has a relative parallax of mas, and its correction from relative to absolute parallax is mas. This yields an absolute parallax of mas, with a standard deviation of mas, which corresponds to a distance of pc, or ly..

Lithium and clouds

Observations published in 2007 showed that the atmosphere of LP 944-20 contains much lithium and that it has dusty clouds.
