Like the vast majority of stars of in the Solar neighborhood, Gliese 402 is a dim red dwarf. With an apparent magnitude +11.66, it is far too dim to be seen with the naked eye; it can only be seen with a telescope. Its luminosity is only 0.091% of times that of the Sun. Its spectral type is M4V (sometimes cited as M5V) and its effective temperature is about 3100 K. Its physical characteristics are quite similar to those of Ross 128 or Kruger 60 B, with a radius of about 30% of the Sun. Its projected rotation speed is at most 2.3 km/s or less, while its metallicity is slightly lower than that of the Sun.
Gliese 402 is a member of the AB Doradus moving group, a moving group that contains about 30 stars.
