light-years

Catalog numbers:
     Gliese (Gl) 900, Bonner Durchmusterung (BD) +0°5017, Hipparcos Input Catalog (HIC) 116384, Vyssotsky McCormick (McC) 81
Arity: singular
Points of interest:
     According to Freming et al. in 1988, this star is an X-ray source, and as such would probably not be amenable to life as we know it on planets orbiting it.
