Dinosaur Big City Part 4
Get Into Nature!
The Pteranodon family rides a special "Night Train" to another part of the Cretaceous Time Period, where they meet a Troodontid "cousin" of the Conductor's, Sydney Sinovenator, who knows more about the stars than anyone. Sidney takes the family up to his favourite stargazing spot, "Starry Hill," and teaches the kids why the stars seem to move across the night sky.
- Cretaceous Period
The stars we see in the night sky are actually suns like our own sun, but they appear to us as tiny pinpoints of light because they are so far away from us. The stars we see in the night sky change over the course of the night, because the earth rotates as it travels around the sun.
