4 Vulpeculae is a single,[7] orange-hued star in the northern constellation of Vulpecula. It forms part of the asterism, formerly thought to be an open cluster, called the coathanger or Brocchi's Cluster.[8][9] The star is faintly visible to the naked eye with an apparent visual magnitude of 5.16.[2] The distance to this star, based upon an annual parallax shift of 12.5320±0.1008 mas,[1] is around 260 light years.

At the age of about 2.6 billion years old,[2] this is an aging giant star with a stellar classification of K0 III,[2] having exhausted the supply of hydrogen at its core and evolved off the main sequence. It is now a red clump giant, indicating that it is on the horizontal branch and is generating energy through the fusion of helium at its core.[10] The star has an estimated 1.72[2] times the mass of the Sun and has expanded to 11.42[1] times the Sun's radius. It is radiating 67.6[2] times the Sun's luminosity from its enlarged photosphere at an effective temperature of 4,763 K.[2]
