Messier 32 facts for kids
M32 is a satellite galaxy of the large Andromeda Galaxy (M31). It was discovered by Guillaume Le Gentil in 1749. M32 measures 6.5 ± 0.2 thousand light-years in diameter at the widest point.
Densities in the central area increase steeply, over 3×107 M⊙ pc−3 as seen by the HST. The half-light radius of this central star cluster is around 6 parsec. In other words, this small centre of the galaxy emits half the light of the central 100 parsecs.
Like more ordinary elliptical galaxies, M32 contains mostly older faint red and yellow stars with practically no dust or gas and consequently no current star formation. It does, however, show hints of star formation in the relatively recent past. M32 contains a supermassive black hole. Its mass is between 1.5 and 5 million solar masses.
