HD 5319 is an 8th magnitude star approximately 370 light years away in the constellation Cetus. It is a giant star of spectral type K0, having run out of hydrogen in its core. When it was main-sequence, the spectral type was early F or late A.

The absolute magnitude (apparent magnitude at 10 parsecs) is 3.05, which would translate to easy naked eye visibility, but its distance is ten times greater, so its apparent magnitude is 8.05 (100 times fainter than its absolute magnitude), it is not visible to the naked eye and binoculars are needed.

Planetary system

On January 11, 2007, the California and Carnegie Planet Search team found a 1.94 MJ extrasolar planet orbiting the giant star. It was published in the December 1, 2007 edition of the Astrophysical Journal.
