The Andromeda Galaxy is approaching the Milky Way at about 110 kilometres (68 miles) per second. [134] It has been measured approaching relative to the Sun at around 300 km/s (190 mi/s) [ 1 ] as the Sun orbits around the center of the galaxy at a speed of approximately 225 km/s (140 mi/s).
Current measurements suggest the Andromeda Galaxy is approaching the Milky Way at 100 to 140 km/s (220,000 to 310,000 mph). In 4.3 billion years, there may be an Andromeda–Milky Way collision, depending on the importance of unknown lateral components to

The distance he found was far greater than the size of the Milky Way, which led him to the conclusion that many similar objects were "island universes" on their own. [ 60 ] [ 61 ] [ 62 ] Hubble originally estimated that the Andromeda Galaxy was 900,000 light-years away, but Ernst Öpik 's estimate in 1925 put the distance closer to 1.5 million ...
