NGC 4145 is a late spiral galaxy in Canes Venatici, 49 million light-years away
NGC 4145 is a late spiral galaxy in the constellation Canes Venatici , 49 million light-years away. It shines at magnitude 11.2 and spans 4.6′ × 2.1′ of sky, about 66,400 light-years across. It is a telescope object, 6 inches or larger, 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.
