Messier object number 101 (NGC 5457) is a spiral galaxy and in the constellation of Great Bear.
It is also known as the Pinwheel Galaxy.It is approximately 21 million lightyears away from earth.
The Pinwheel Galaxy is a spiral galaxy, just like our own Milky Way Galaxy. However, while our own galaxy hosts "only" around 100 billion stars, the Pinwheel Galaxy is really huge, with an estimated one trillion stars. It is around 50-70% larger in size and sits at distance of around 21 million light years. That means, the light we see today travelled 21 million years through space before reaching us. Looking at the Pinwheel Galaxy is like looking 21 million years into the past.
The Pinwheel Galaxy is also known as Messier Object 101 (M101). Charles Messier was a famous astronomer of the 18th and 19th century, who compiled a list of 110 well visible deep sky objects - the Messier Catalog. However, it was not discovered by Messier itself, but by Pierre Méchain in 1781.
Like our Milky Way Galaxy, the Pinwheel Galaxy has a number of much smaller companion galaxies, such as NGC 5204 or NGC 5474.
