HD 5319 [SEP] constellation
HD 5319
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
HD 75898 b
HD 75898 b is an extrasolar planet approximately 255 light years away in the constellation of Lynx. This is a giant planet orbiting the star HD 75898. The minimum mass is two and a half times more than Jupiters, suggesting it is a gas giant. The planet orbits at 1.168 AU from the star, taking 1.1 year to orbit in relatively circular orbit.
