Wow! Is their really bigger stars then the sun. I wonder why I haven't heard of them since today? That’s really weird. It is shocking to see the size of them, they are located below the milky way. I wounder how the stars were formed?. The largest planet is Jupiter. It is followed by Saturn, Uranus, Neptune, Earth, Venus, Mars, Mercury, and finally, tiny Pluto. The brightest star out of all of them is Sirius.
