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. It was discovered by the astronomer William Herschel
on February 5, 1788.
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.
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).
