HD 65750 is located about 900 light years away, and has an apparent magnitude that varies between 6.2 and 7.1 and a metallicity just Шаблон:Val of the Sun. It is part of the Diamond Cluster moving group.

The star has a radial velocity of Шаблон:Val.[4]

Nebulae

The nebulae is a mystery as the variations in nebulae brightness appear to be unrelated to the host star.[5] One theory is that rather than being an accreting protoplanetary disk the star may be an evolved star that is losing material.[6][7]
