Revision as of 15:25, 26 February 2020 by RoySmith (talk | contribs) (Add announcement of exoplanet, and sources.)(diff) ← Previous revision | Latest revision (diff) | Newer revision → (diff)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.
