Comet

• A ball of dust and ice that orbits around the sun.

The Sun

• Center of solar system• A star – ball of hot glowing gas• Very hot and large• All the planets orbit around it.

Name the 4 inner planets in order from the sun.

• Mercury• Venus • Earth• Mars

Name the 5 outer planets in order from the sun.

• Jupiter• Saturn• Uranus• Neptune

How are the inner planets the same?

• Smaller and warmer• Have rocky surfaces• Have no more than 2 moons

How are the outer planets ?

• Made mostly of frozen gas• Larger and colder• Have more than 2 moons

Mercury

• Mercury is solid and is covered with craters.

• Mercury has almost no atmosphere.

• Mercury is the eighth largest planet.

Venus

• Venus is the sixth largest planet. It’s about three-fourths the size of earth.

• The surface is rocky and very hot. The atmosphere completely hides the surface and traps the heat.

Earth

• Earth is the fifth largest planet and the third from the sun.

• Liquid covers 71 percent of the Earth’s surface.• The Earth has one moon.

Moon

Mars

• Mars is the fourth planet from the sun.

• Mars has a thin atmosphere that contains mostly carbon dioxide.

• Mars has two small moons.

Jupiter

Jupiter’s Red Spot

• The Great Red Spot, a huge storm of swirling gas that has lasted for hundreds of years.

• Jupiter does not have a solid surface. The planet is a ball of liquid surrounded by gas.

Saturn

• Saturn is the second largest planet and the sixth from the sun.

• Saturn is made of materials that are lighter than water. If you could fit Saturn in a lake, it would float!

Rings of Saturn

• Saturn’s rings are not solid; they are composed of small countless particles.

• The rings are very thin. Though they’re 250,000km or more in diameter, they’re less than one kilometer thick.

Uranus

• Uranus is the third largest planet and the seventh from the sun.

• Uranus is one of the giant gas planets.

• Uranus is blue-green because of the methane in its atmosphere.

Neptune

• Neptune is the fourth largest planet and the eight from the sun.

• Because of the orbits, from 1979 to 1999, Neptune was the ninth planet.

• Like Uranus, the methane gives Neptune its color.

What planet is the largest?
