7 Vulpeculae is a binary star system approximately 910 light years away in the slightly northern constellation of Vulpecula. It is a challenge to view with the naked eye, having an apparent visual magnitude of 6.3. The system currently has a heliocentric radial velocity of −38 km/s.

This is a single-lined spectroscopic binary star system with an orbital period of 69.3 days and an eccentricity of 0.16. The visible component is a Be star with a stellar classification of B4–5 III–IVe that appears to be nearing the end of its main sequence lifetime. The system shows a rapid projected rotational velocity of 300 km/s, which is just below the estimated critical velocity for a binary of 367 km/s.

There is a small variability in the magnitude over a 0.559-day cycle; this is likely the rotation period of the primary star.

The companion is a hot subdwarf, either a subdwarf B or subdwarf O star, with a mass of 48% the Sun's mass. It has a close orbital separation of half an astronomical unit and take 69 days to complete an orbit.
