3. The Sun
• The Scientific name is Sol.
• It contains about 98% of all the rocks, dust, and
gas in the Solar System.
• If hollow, one million Earths could fit inside.
• It acts as a giant magnet.
• The Sun’s surface is 6,000 degrees celcius, but it’s
atmosphere is millions of degrees.

4. Mercury
• It takes 87,969 days for Mercury to orbit the Sun one time.
• Since it is smaller than Earth, it has less gravity which
means if you weighed 70 pounds on Earth, you would
weigh 27 pounds on Mercury.
• Mercury is so hot that you could burn to death during the
day, but spins so slowly that you could freeze to death at
night.
• It has no moons.
• There is almost no air on Mercury.
• It is 36 million miles away from the Sun.

5. Venus
• It takes 224,701 days to orbit the Sun.
• You would way 63 pounds here if you weighed 70
pounds on Earth.
• It is similar to Earth because it has mountains,
venusquakes, mountains and valleys. You can’t
live here though because it is way too hot.
• It is 67 million miles away from the Sun.
• Venus has no moons.

6. Earth
• It takes Earth 365.3 days to orbit the Sun.
• We are 93 million miles away from the Sun
• It contains the only human life we know of.
• Earth has one moon, Luna.
• Earth has just the perfect combination of
weather, temperature, and atmosphere to keep
us alive.

7. Mars
• It takes 686.98 days to orbit the Sun.
• Mars is 142 million miles away from the Sun.
• Weighing 70 pounds on Earth, you would weigh 27 on
Mars.
• Scientists have found that Mars once had streams, rivers,
lakes, and an ocean.
• Mars has two moons, Deimos and Phobos.
• Mars has the highest mountains and deepest canyons in
the whole Solar System. The largest canyon on Mars would
stretch from New York to California here on Earth.

8. Jupiter
• It takes Jupiter 4332.59 days to complete one orbit around the Sun.
• It is 482 million miles away from the Sun.
• You would weight 185 pounds on Jupiter if you weighed 70 pounds
on Earth.
• Jupiter has a great red spot that is made up of storms that have
been constantly occurring for over 300 years.
• There is no solid surface here, it is just one huge ocean of Hydrogen
and Water. There is nothing in between the atmosphere and the
ocean, there would be no flat surface to float a boat on like on
Earth.
• Jupiter has 63 moons.
• It only takes 10 hours to go from night to day here.
Home

9. Saturn
• It takes 10,759.2 days to orbit the Sun.
• You would weigh 82 pounds here if you weighed 70
pounds on Earth.
• It’s rings are 169,800 miles wide, but less thick than a
football field.
• Saturn is very similar to Jupiter because under it’s
atmosphere is an ocean of liquid chemicals.
• Saturn has 34 moons.
• It is 888 million miles away from the Sun.
Home

10. Uranus
• It takes 30,684 days for Uranus to orbit the Sun.
• It is 1, 784 million miles away from the Sun.
• You would weigh 82 pounds here, if you weighed 70
pounds on Earth.
• It is the only planet that spins on it’s side.
• Uranus could have ocean under it’s atmosphere, and
because of the amount of pressure on Uranus, it could
possible have trillions of large diamonds.
• It is almost identical to Neptune.
• It has 27 moons.
Home

11. Neptune
• It takes 60,190 days to orbit the Sun.
• Neptune has a giant storm just like Jupiter, it is called
the Great Dark Spot.
• It was discovered in 1846.
• It has 6 rings that surround it.
• Since Neptune is so far away, scientists know of 13
moons for sure, but there could be many more to be
discovered.
• It is 2,794 million miles away from the Sun.

13. Review: two main types of planets
Terrestrial
-relatively small,
dense solid, rocky
surfaces, metals in
interior, closer to
Sun
Mercury, Venus,
Earth, Mars, various
moons
Jovian
- larger, smaller average
density, ‘gas giants',
made of H, He, hydrogen
compounds (water,
methane, ammonia) very
dense interiors, farther
from Sun, rings,
rocky or icy moons
Jupiter, Saturn, Uranus,
Neptune
