1 Vulpeculae is a class B4IV[1] (blue subgiant) star in the constellation Vulpecula. Its apparent magnitude is 4.77[2] and it is approximately 780 light years away based on parallax.[3]
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.[4] There are also companions B, with magnitude 11.6 and separation 39.1", and C, with magnitude 12.8 and separation 43.6".[5][6]
Component A is also a suspected variable star, reported to vary from 4.57 to 4.77 in magnitude.[7] It was reported as possibly variable in 1952 during a search for β CMa variables,[8] but has not been seen to vary since. It was listed as one of the least variable stars based on Hipparcos photometry.[9]
On 29 May 1983, 1 Vulpeculae was occulted by the asteroid Pallas. This event was observed at 130 locations in the United States and Mexico and was the best observed of all asteroid occultation events.[10]
