There is a difference between asterisms, asteroids, and hemorrhoids. How many of you know what the difference is? Well, it hurts when you sit on hemorrhoids, asteroids could hit you on the head, and you have all seen asterisms. If any of you have ever looked up after dark, I bet you have seen some asterisms. In fact, I will go out on a limb and bet every one of you have seen at least one asterism.
I guess for those who are not sure what an asterism is, I will give you the definition. "An asterism is a pattern of stars seen in Earth's night sky." OK, does that help at all? How about some examples. I bet everyone has seen the big and little dippers, right? Well, at least everyone but those who live close to the south pole. Both of those are asterisms that belong to larger constellations, Ursa Major and Ursa Minor. This picture will show the asterism (brighter) and the complete constellation:
Yes, it is the great bear, but most people only see the dipper. There are a lot more, but I believe this one can be identified by most everyone. So, from now on, do not call the dippers constellations, because they are only part of a constellations. Some asterisms are part of multiple constellations. They are the pictures in the night sky. Now, you all have a great day and a great night, you hear?
