My friend Tina is a teacher in Austin. She asked her sixth grade students to send me questions they had about astronomy, and I answer them on question. There were so many I had to split this into *5* parts!
This is Part 3, and these are the questions they asked me:
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?
