It is a yellow dwarf star with a mass around 0.92 times that of our Sun. Since its distance is about 69 light years, it is not visible to the unaided eye. With binoculars it is easily visible. The star has a massive extrasolar planet orbiting it. Also, in 1999 the discovery of a circumstellar disk was announced by T. E. Trilling et al. based on observations in infrared wavelengths. The disk is probably similar to the Kuiper belt in our Solar system.
