IC 2448 is an elliptical planetary nebula in the constellation of Carina. It was discovered in 1898 by Williamina Fleming.[3] It lies near the bright star Beta Carinae. The central star of the planetary nebula is an O-type star with a spectral type of O(H)3 III-V.[4] An analysis of Gaia data suggests that it is a binary system.[5]
