16 Delphini
16 Delphini is a star in the northern constellation of Delphinus. It has an apparent magnitude of 5.54, making it faintly visible to the naked eye. The star is relatively close at a distance of 198 light years but is receding with a poorly constrained radial velocity of 2 km/s.
16 Delphini is a chemically peculiar A-type main-sequence star with a stellar classification of A5 V. It has twice the Sun's mass, 1.9 times its radius, and shines at 18.7 L☉. This yields an effective temperature of 9,039 K, giving it a white glow. 16 Del is 400 million years old – 56.5% through its main sequence lifetime – and spins rapidly with a projected rotational velocity of 159 km/s.
16 Del has a companion that was first discovered by John Herschel and was even noted to be a spectroscopic binary. It is now considered to be a single star.
