Arp 286 - Galaxy Trio

Arp 286 is an interacting galaxy system from the Atlas of Peculiar Galaxies compiled by Halton Arp, located in the constellation Virgo. It consists of a trio of interacting spiral galaxies: NGC 5566, NGC 5560, and NGC 5569. The distance to Earth is estimated at about 67 to 79 million light-years.

The dominant galaxy of the system, NGC 5566, is a barred spiral galaxy with a diameter of approximately 135,000 to 150,000 light-years, making it one of the largest members of the Virgo-III galaxy group. NGC 5560 is noticeably distorted and appears stretched due to its gravitational interaction with NGC 5566, while NGC 5569 shows a smaller, bluish spiral structure.

The mutual gravitational influences generate tidal forces that reshape the morphology of the trio. Arp 286 is considered a prime example of how galaxies are deformed by interacting forces and can eventually merge over time.
