This spiral galaxy belongs to the Local Group of galaxies wich and our own galaxy. After Andromeda's galaxy and our own, the triangulum galaxy (m33) is the third largest in the Local Group. 2.8 million light years from us, with apparent brightness 5,69 and apparent size of 68x41 minutes of arc. It appears from us inclined approximately 54 degrees, which helps to better illustrate the two arms. He is farthest object visible to the naked eye from Earth, but under completely dark sky. Although bright, because it has a large area in the sky (4 four times larger area than that occupied by our moon) is best visible with good binoculars of low magnification. The size, although in relation to the Andromeda's galaxy and our own, is small (diameter of about 60,000 light years), however appear to be more usual size galaxy. Its mass is estimated at 10-40 billion solar masses, and contains 30-40 billion stars. It contains the largest known H II region (NGC 604, with a diameter of 1,500 light years) and contains just 200 formed hot stars, size 15-60 times the mass of our sun. Although there have not been discovered to date supernova in this galaxy, however,we have found several novel residues explosions. In 2007 discovered a black hole with a mass 15.7 times that of our sun in the ecliptic orbit in a star during 3.5 days (M 33 X-7).
