Note: There is a special note to teachers at the bottom of this post. If you're a teacher, please be sure to check it out!

My friend Tina is a teacher at the Saegert Sixth Grade Center in Austin, Texas. She asked her sixth grade students to send me questions they had about astronomy, and I answer them on camera. There were so many I had to split this into five parts! I'll be posting one part every day, first thing in the morning. To catch you up, check out Part 1 and Part 2. Below is Part 3.

The questions asked in Part 3 are:

1) How do planets form?

2) Does Mars have polar ice caps?

3) What's a meteoroid?

4) How do we measure temperatures on distant planets?

5) How large is the asteroid belt?

6) What happened to "Planet X"?

7) Can the Earth blow up?

SPECIAL NOTE TO TEACHERS: Many schools block access to YouTube. There is another video hosting platform called TeacherTube, which is designed to be used in schools. I've uploaded this video (Part 3) to my channel there, where you can access it in your school (note: the video is in higher-resolution on YouTube). If you do, please let me know! I'd love to know what the students thought of the video -- warts and all.
