HD 61330 (f Puppis) is a class B8IV [4] (blue subgiant) star in the constellation Puppis. Its apparent magnitude is 4.53 [3] and it is approximately 360 light years away based on parallax. [2]
It is a multiple star, with a secondary component C, with magnitude 6.07 in an 81-year orbit with eccentricity 0.64. [7] Another closer component, B, has been reported at 6.1 magnitude and 0.1" separation, but subsequent observers have repeatedly failed to confirm it. [8]
