NGC 2683 is a field spiral galaxy in the northern constellation of Lynx. It was nicknamed the "UFO Galaxy" by the Astronaut Memorial Planetarium and Observatory.[3][4] It was discovered by the astronomer William Herschel on February 5, 1788.[5]
It is viewed nearly edge-on from Earth's location in space and is located about 30 million light-years away,[2] although previous estimates also give distances between 16 and 25 million light-years.[6]
NGC 2683 is receding from Earth at 410 km/s (250 mi/s), and from the Galactic Center at 375 km/s (233 mi/s).[3]
