24 Vulpeculae is a single,[1] yellow-hued star in the northern constellation of Vulpecula. It is faintly visible to the naked eye with an apparent visual magnitude of 5.30.[2] The distance to this star can be estimated from its annual parallax shift of Template:Val,[3] which yields a separation of roughly 409 light years. It is moving further away with a heliocentric radial velocity of +15 km/s.[4]
This is an evolved giant star with a stellar classification of G8III,[2] having exhausted the hydrogen at its core and moved off the main sequence. It is a red clump giant, indicating it is presently on the horizontal branch and is generating energy through helium fusion in its core region.[5] The interferometry-measured angular diameter of 24 Vul is Template:Val,[6] which, at its estimated distance, equates to a physical radius of about 16 times the radius of the Sun.[7]
24 Vulpeculae is about 251[2] million years old and is spinning with a projected rotational velocity of 5.02 km/s.[8] It has 3.41 times the mass of the Sun and is radiating 191 times the Sun's luminosity from its enlarged photosphere at an effective temperature of 4,981 K.[2] This is the probable (99.4% chance) source of X-ray emission coming from these coordinates.[9]
