SON: How far away is Mars?
DAD: Well, it's 141 million miles from the sun, so
pretty far.
SON: Why is it red?
DAD: Because its surface is made of iron oxide.
SON: Why do they call it Mars?
DAD: Well, it was named after the
Roman god of war.
SON: You're so smart, Dad.
DAD: Did I ever tell you about Jupiter?
