Star

Wittrock et al. (2016): HD 2638 has a late-type M dwarf companion (0.483 solar mass and a temperature of 3570K) with a projected separation of 25.6 +/- 1.9 AUs as well as a visual G dwarf companion star (HD 2567, spT G1V) 45,720 AUs away (González-Payo et al. 2024). The latter is the true primary component of the triple system.
