  7. Earth • Many years ago people thought Earth was flat. • Earth is about 93 million miles from the sun. • Earth’s atmosphere is made of gases & bits of dust & water. • Earth is like a giant magnet. • The lands on earth’s surface are always changing .

  8. Mars • Fourth planet from the sun. • Mars has 2 moons. • Mars has no rings. • One year has 687 days. • One day has 24.5 Earth hours.

  9. Mars • Mars is more than 140 million miles from the sun. • It’s 4,218 miles across. • Mars was very hot inside. • Mars is a dusty planet. • Millions of years ago when it was a young planet it may even have had oceans.

  10. Jupiter • Fifth planet from the sun. • At least 16 moons. • It has 2 rings. • One year is 4,280 days. • It takes 9.8 hours to spin on its axis.

  11. Jupiter • It’s about 480 million miles from the sun. • One mystery on Jupiter is the Great Red Spot. • The temperature here is very cold. • The planet is very hot in its center. • If you weigh 100lb on Earth you would weigh 264lb on Jupiter.
