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, and the southern Carina can be explored in the months of autumn in the southern hemisphere.^{[citation needed]} 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]
