What is the procedure of renaming Cool Planet Names?

The International Astronomical Union is the official authority on naming astronomical objects. They have a very strict naming protocol, which has gone mostly unchanged since the early 20th century. If a new planet is discovered, it will (most likely) get a provisional name based on when and where it was first observed. Then after further observation and analysis, it will be given an official name in order to avoid confusion with other planets that were discovered around the same time.

Revamping your Cool Planet Names with these ideas

The stars have had some of the most interesting names, coming from a variety of different origins. Some are named in Greek, like Betelgeuse, which means “armpit of the giant”. Others are named after the people who discovered them, or their astronomical achievements. And with star names having such diverse sources, there is no reason why you can’t come up with your own planet or star name!

Cool Planet Names suggestions with meaning

When you are naming anything, you want to be creative, but it’s also important to make sure that the name is meaningful. The name should describe something about the object so that other people will understand what the name means when they see it. If the purpose of naming is simply to rename a planet or star, then sometimes picking a meaningful Cool Planet Name can be an easy and beautiful way to name something.
