Study Guide & Educational Overview
### Fun Space Facts for Junior Astronauts:
* **The Eight Planets**: Mercury (closest to the Sun), Venus (hottest planet), Earth (our watery home), Mars (the Red Planet), Jupiter (biggest planet with the Great Red Spot), Saturn (spectacular rings), Uranus (rolls on its side), and Neptune (windy blue planet).
* **Living in Space**: Astronauts wear bulky white spacesuits to breathe; in microgravity, everything floats, so they sleep in sleeping bags strapped to walls and eat tortillas!
* **Moon Explorers**: Neil Armstrong was the first person to walk on the Moon during Apollo 11 in 1969; the Moon has no wind or rain, so footprints last for millions of years.
* **Stars & Galaxies**: The Sun is our nearest star; comets are dirty snowballs with glowing tails; and our solar system lives in the spiral Milky Way galaxy.
