SPIRAL GALAXY The Milky Way is a spiral galaxy, A spiral galaxy is disk-shaped with a bulge in the middle and arms that spiral out from the bulge. The arms rotate around the galaxy’s center

ELLIPTICAL GALAXY An elliptical galaxy is shaped like a flattened or partially deflated football. Such galaxies contain trillions of stars. These galaxies either do not rotate at all or rotate much more slowly than spiral galaxies.

IRREGULAR GALAXY As its name suggests, an irregular galaxy does not have a distinct shape. Irregular galaxies are the least common type of galaxy. However, two of the closest galaxies to our own galaxy – the Large and Small Magellanic clouds are irregular galaxies.

OUR SUN Main sequence star Considered to be a young star Medium sized Our closest star Located near the end of one of our Milky Way spiral arms The sun is the only star in our solar system. The next closest star, Proxima Centouri, is 4.2 ly away
