HD 5319 is an 8th magnitude star approximately 397 light years away in the constellation Cetus. It is a subgiant star of spectral type K3, 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 an extrasolar planet with a minimum mass 1.76 times that of Jupiter orbiting the star. It was published in the December 1, 2007 edition of the Astrophysical Journal.[4] A second planet was discovered in 2015. Orbital simulations of the dynamical stability of the planetary system indicate that it is likely in a 4:3 mean motion resonance.[2] Previous computer simulations have shown an inability to reproduce this resonance in gas giant systems using a variety of formation and migration mechanisms.[5] Additional analysis on the stability of the system show that the planets orbits may have to be inclined to one another to maintain stability.[6]
