The Milky Way is a barred spiral galaxy with a D 25 isophotal diameter estimated at 26.8 ± 1.1 kiloparsecs (87,400 ± 3,600 light-years), [10] but only about 1,000 light-years thick at the spiral arms (more at the bulge).
The galactic year, also known as a cosmic year, is the duration of time required for the Sun to orbit once around the center of the Milky Way Galaxy. [1] One galactic year is approximately 225 million Earth years . [ 2 ]
Also called VV 32 and Arp 148, this is a very peculiar looking object, and is likely to be not one galaxy, but two galaxies undergoing a collision. Event in images is a spindle shape and a ring shape. [citation needed] Milky Way: Sagittarius (centre) The appearance from Earth of the galaxy—a band of light [citation needed]
The Local Group is the galaxy group that includes the Milky Way, where Earth is located. It has a total diameter of roughly 3 megaparsecs (10 million light-years; 9 × 10 19 kilometres), [1] and a total mass of the order of 2 × 10 12 solar masses (4 × 10 42 kg). [2]
