GJ 1151 is a star located in the northern circumpolar constellation of Ursa Major at a distance of 26.2 light-years (8.0 parsecs) from the Sun. It has a reddish hue and is too faint to be visible to the naked eye with an apparent visual magnitude of 14.0^[2] The star is moving closer with a radial velocity of −36 km/s,^[5] and has a relatively large proper motion, traversing the celestial sphere at a rate of 1.815″·yr⁻¹.^[7]

This is a small red dwarf star of spectral type dM4.5.^[2] It is 2.5^[3] billion years old and is spinning with a projected rotational velocity of 2.0 km/s.^[5] The star has 15.4%^[3] of the mass of the Sun and 19.0%^[3] of the Sun's radius, with an effective temperature of 3,143 K.^[2]
