Faint ΔKs = 12.16 companion with a separation of 3.73 arcseconds from the central star
Faint ΔKs = 12.16 companion with a separation of 3.73 arcseconds from the central star. Follow-up observations revealed its background nature through proper motion arguments. If it were at the same distance as G173-39, it would correspond to a ~10 Mjup companion at 53.4 AU.
