LEDA 74886 LEDA 74886 LEDA 74886, also known by its 2MASX designation 2MASX J03404323-1838431, is a dwarf galaxy with a rare rectangular shape. It is located at a distance of about in the Eridanus constellation. The galaxy was detected in a wide field of view image taken by the Subaru Telescope using the Subaru Prime Focus Camera (Suprime-Cam). Using the Keck Telescope, a thin disc with a side on orientation was confirmed to be lurking at the center of LEDA 74886, and spinning at a speed of 33 km/s at the orbital radius of half a kpc. LEDA 74886 has a mass
