NGC 3309 is a giant elliptical galaxy[2] located about 200 million light-years away[3] in the constellation Hydra.[4] NGC 3309 was discovered by astronomer John Herschel on March 24, 1835.[5][6] The galaxy forms a pair with NGC 3311[7] which lies about 72,000 ly (22 kpc) away.[8] Both galaxies dominate the center[7] of the Hydra Cluster.[9]
