Its apparent magnitude is 4.77 and it is approximately 780 light years away based on parallax. The primary was discovered to be a spectroscopic binary in 1978 with a period around 250 days although the orbital elements are described as marginal. There are also companions B, with magnitude 11.6 and separation 39.1", and C, with magnitude 12.8 and separation 43.6".2002yCat.1274....0D VizieR Online Data Catalog: CCDM (Catalog of Components of Double & Multiple stars) (Dommanget+ 2002) VizieR On-line Data Catalog: I/274.
