Greetings dear student, I am very happy to see your participation. You did a good job explaining the solar system and the theories. I have a few comments to make about the last point where you chose "The Central Star" and the closing of your post.

1. In the subtitle you put "solar body" but the correct form is "celestial body".

2. The Sun is not a system, it is an element of the solar system.

3. The Sun is made up of hydrogen and helium, "melium" is not a compound.

4. In closing you said that you met many solar systems. However, there is only one and it was explained in the lesson. Of course, other systems with a central star and bodies orbiting it have been discovered, but the one with the official name "solar system" is where our planet belongs.

The Sun was a great option, it is an essential element for life on planet Earth. Despite the comments, you did a good job.

I am very glad that you have learned something new about Earth sciences and I hope to see you soon in the next lessons. Congratulations!!
