"The sun is far away. About 93 million miles away, and that's why it looks so small," according to a song by They Might Be Giants, which plays during a demonstration of the Radiant Pro 60 on Tuesday at the planetarium at Rock Bridge High School. They Might Be Giants' "Why Does The Sun Shine?" is an educational song released in 1993.
