M99

M99 or M-99 may refer to:* Messier 99, an unbarred spiral galaxy approximately 60 million light-years away in the constellation Coma Berenices... , The Dharma Bums The Dharma Bums ...

M99 = NGC4254 ( 12h 18.8m +14°25´, 9.8 mag. ) This face-on spiral galaxy in Coma Berenices was discovered by Mechain in 1781 and Messier observed it on April 13 same year.

M99 is roughly one and a half degrees east-southeast of M98. An open spiral seen face on, its several arms are visible in large scopes. It has a brightness of 9.8.

Another Virgo cluster member in Coma Berenices is a spiral galaxy known as M99. It is unusual in appearance in that its shape is very asymmetric.

Here lies our next object, M99, better known as the Pinwheel galaxy. The Pinwheel, otherwise known as NGC 4254, has a brightness between that of M100 and NGC 4450. M99 is a spiral galaxy, much like our own Milky Way in structure.

It has a small nucleus and faint but vast spiral arms. M99 (NGC 4254), about 1.5° southeast of M98, is a bright, round spiral seen face-on. R.H. Allen called it the "Pinwheel nebula", although this name is more often applied to Spiral galaxy M33.
