Type Galaxy Constellation Triangulum Magnitude 7.0 Apparent size 73′ × 45′ (2× the full Moon) You need binoculars Known as Messier M33 Dreyer NGC 598 Physical Distance 2.7 million light years More information about Triangulum Galaxy The Triangulum Galaxy is large and diffuse, which makes it a poor target for a telescope and a good one for binoculars. Under genuinely dark skies some people can see it with the naked eye, which makes it a reasonable contender for the furthest thing visible unaided. History Discovered 1654, Giovanni Battista Hodierna Messier was hunting comets. He compiled his list between 1758 and 1781 as a register of things that look like comets but are not. That's why the objects on it have nothing in common beyond being fuzzy and staying put. Dreyer compiled the New General Catalogue in 1888, mostly from the sweeps William and John Herschel made of the sky, and numbered its 7,840 objects in order of right ascension. where it is tonight: skymap.sh/Triangulum Galaxy
