The Pinwheel Galaxy
Transcript of The Pinwheel Galaxy
A face on spiral-like galaxy
The largest galaxy known to man
The brightest lit galaxy. Pinwheel has a diameter of 170,000 light-years! It's also almost TWICE the size of the Milky Way! Pinwheel is about 27 million light-years away from us. It could take years to get there, if that were even possible to reach it! The pinwheel galaxy supports many other planets and stars of its very own just like the Milky Way does. We don't know very much about it, but if we could visit, it is likely that there is life somewhere. It's a HUGE galaxy! Pinwheel has many names it goes by,
the most popular being "Messier 101"
or "M101". It is also known as NGC 5457. As you can see, this galaxy is shaped much like a pinwheel, which (obviously) is how it got its name. It also shows that it is a very brightly lit galaxy. Messier 101 was discovered
