GJ 1151 is a red dwarf star of spectral type M4.5V, located in constellation Ursa Major at 26.7 light-years from Earth.

In 2020, astronomers announced the discovery of radio emissions from the star which are consistent with a planet, approximately the size of Earth, rotating in a 1-5 day long orbit.

Distance

In 1991, Gliese et al gave parallax (πp) as 121.8 ± 3.0 mas. In 1995, van Altena gave parallax as 122.1 ± 2.9 mas. In 2014, Dittman et al gave parallax as 130.60 ± 3.60 mas.
