The galaxy was discovered by William Herschel on 5th February 1788 using his selfmade 18.7 inch reflecting telescope. He cataloged it as I 200 and described it as follows: «Very brilliant, much elongated, south preceding north following, 8' long 3' broad beautiful.» [464] John L. E. Dreyer cataloged the galaxy then as NGC 2683 in his «New General Catalogue» of 1888. [313] Due to its resemblance of a flying saucer, it got the nickname «UFO Galaxy».

Physical Properties

NGC 2683 is galaxy seen almost edge-on. Spectroscopic and photometric observations have shown, that it has a central bar which is 6° away from the galaxy's major axis. One can see the delicate dusty lanes of the spiral arms silhouetted against the galaxy's core. Brilliant clusters of young blue stars shine scattered throughout the disc, mapping the galaxy’s star-forming regions. [517, 518] Measured distances are ranging from 7.5 Mpc to 12.4 Mpc (24 to 40 million light years). [145]
