LEDA 74886, also known by its 2MASX designation 2MASX J03404323-1838431, and sometimes known as the Emerald-cut Galaxy,[4] is a dwarf galaxy with a rare rectangular shape.[2] It is located at a distance of about 70,000,000 light-years (21 Mpc) in the Eridanus constellation.[5] The galaxy was detected in a wide field of view image taken by the Subaru Telescope using the Subaru Prime Focus Camera (Suprime-Cam).[6][7] 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.[2] LEDA 74886 has a mass of around 109 M (Compared to the Milky Way's mass of about 1012 M).

Location[edit]

LEDA 74886 is located in the celestial sphere at a right ascension () of 03h40m 43.2s, and a declination () of −18° 38′ 43″ (J2000). It is located within the Galactic coronaofNGC 1407, a massive spherical galaxy which is located approximately 163,000 ly (50 kpc) to the northwest of LEDA 74886.[2]
