NGC 1098 is a lenticular galaxy in Eridanus, 234 million light-years away
NGC 1098 (ESO 546-014) is a lenticular galaxy in the constellation Eridanus , 234 million light-years away. It shines at magnitude 12.7 and spans 1.6′ × 1.3′ of sky, about 107,500 light-years across. It is faint: a 10-inch or larger telescope, or a camera, and it is highest in the evening sky in December.
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.
