GJ 388 (AD Leonis) is a red dwarf star. It is located relatively near the Sun, at a distance of about 16 light years, in the constellation Leo.
This is a main sequence star with a spectral classification of M3.5V. It is about 39–42% of the Sun's mass and 39% of the Sun's radius. The projected rotation of this star is only 3 km/s.
This is a UV Ceti variable star that undergoes random increases in luminosity and has the variable star designation AD...

GJ 388 (AD Leonis) is a red dwarf star. It is located relatively near the Sun, at a distance of about 16 light years, in the constellation Leo.
This is a main sequence star with a spectral classification of M3.5V. It is about 39–42% of the Sun's mass and 39% of the Sun's radius. The projected rotation of this star is only 3 km/s.
This is a UV Ceti variable star that undergoes random increases in luminosity and has the variable star designation AD Leonis. It is one of the most active flare stars known, and the emissions from the flares have been detected across the electromagnetic spectrum as high as the X-ray band. The net magnetic flux at the surface is about 3 kG. Besides star spots, about 73% of the surface is covered by active regions.
A search with a near-infrared speckle interferometer failed to detect a compaion orbiting 1–10 AU from the star. An optical coronagraph failed to discover a companion. This star is orbiting through the Milky Way galaxy with an eccentricity of 0.028,...
