Welcome!
Hello and welcome to Wikipedia. Unfortunately, your edit to Kepler's laws of planetary motion has introduced a factual error: There are three laws, you've added a non-existant "fourth law" to the article.

The Wikipedia tutorial is a good place to start learning about Wikipedia. If you have any questions, see the help pages, add a question to the village pump or ask me on my talk page. By the way, you can sign your name on Talk and discussion pages using four tildes, like this: &#126;&#126;&#126;&#126; (the software will replace them with your signature and the date). Again, welcome! ~ ToBeFree (talk) 16:01, 16 July 2019 (UTC)
