IC 4273 is a lenticular galaxy in Hydra
IC 4273 (ESO 444-065) is a lenticular galaxy in the constellation Hydra . It shines at magnitude 15.0 and spans 57″ × 36″. It is faint: a 10-inch or larger telescope, or a camera, and it is highest in the evening sky in May.
Galaxy: a system of billions of stars, gas and dust held together by gravity, far outside the Milky Way. Spiral galaxies have a disk with arms; elliptical galaxies are smooth, round or oval swarms of older stars.
