  GJ 1005 Location of GJ 1005 in the constellation Cetus | ||
GJ 1005 is a system of two red dwarfs, located in constellation Cetus at 19.6 light-years from Earth.[7] The primary star is a M4V class star while the secondary is a class M7V.[citation needed]
The system was observed with the Hubble Space Telescope in the 1990s with its Fine Guidance Sensor.[7] This data helped determine the mass of each of the components of L722-22/ LHS 1047 / GJ 1005.[7]
