TOI-6894 is a star in the constellation Leo. Its apparent magnitude of 18.22 is far below naked eye visibility. Based on parallax measurements, it lies at a distance of 238 light-years (73 parsecs). The star was first catalogued in 2003 by the 2MASS survey, and was analysed by the TESS satellite in search for transiting exoplanets.
This is a red dwarf of spectral class M5.0. It has 0.207 times the Sun's mass, 0.2276 times the Sun's radius, and a mere 0.38% of the solar luminosity. Its effective temperature of 3,000 K give it a typical red hue. The iron-to-hydrogen abundance ratio, a metallicity indicator, is 40% higher than that of the Sun. As of 2025, the discovery of TOI-6894 b makes the star the least massive star known to host a transiting gas planet.
