What are planets?

• Objects that orbit the sun.
• Objects that are large enough to become round due
  to its gravitational pull.
• Planets are tidy, which means that they are able
  to sweep up asteroids, comets, and other debris.
  By the planets orbit being tidy, it helps clear
  a path for the planets to orbit the sun.

Mercury

• Is the closest planet to the sun and it is
  smaller than Earth in size.
• It is tiny and rocky.
• It has no water and very little air.
• It does not have a blanket of air around it so
  Mercury gets very hot during the day.
• Mercury has an atmosphere (layer of gas that
  surrounds the planet).
• It gets very cold at night.
• You are not able to live on Mercury.
• Mercury has craters and mountains like the moon.
• There is no moons on Mercury
• It takes Mercury 88 days to orbit the Sun.

Venus

• the second planet from the sun.
• Venus is about the same size as Earth.
• Venus is a very bright planet.
• Venus has thick layers of clouds around it, which
  makes Venus the hottest planet.
• Venus has no water.
• Venus has many volcanoes and is covered with rock
  and ash.
• It takes about 225 days for Venus to complete its
  orbit around the Sun.

Earth

• Earth is our home and it is the third planet from
  the sun.
• Earth is the only planet that has life on it.
• On Earth you can find liquid water and oxygen.
• Earth has an atmosphere and that helps keep the
  planet from getting too hot or too cold.
• Earth has mountains, deserts, valleys, forests,
  and some frozen land.
• The Moon is Earths only satellite.
• Earth completes one revolution around the Sun
  every 365 days.

Mars

• Is the fourth planet from the sun.
• Mars is called the Red Planet because it has red
  rocks and rust in the soil.
• Mars takes about two years to orbit the Sun.
• Mars has many volcanoes.
• Mars also has canyons, craters, and valleys.
• There is wind on Mars, which causes huge dust
  storms.
• There is no liquid water in Mars, but there is
  ice at the poles in Mars.
• The scientists believe that there might have been
  liquid water and life on Mars, but nothing has
  been found to prove that yet.

Jupiter

• Fifth planet from the Sun.
• It is huge and bigger than all the other planets
  put together
• Jupiter has rings and is made up of gases.
• On Jupiter the gases form the Great Red Spot.
• 1 Jupiter year is almost 12 Earth years
• There are short days like 10 Earth hours long.

Jupiter
14
Saturn

• It is the sixth farthest planet from the Sun.
• It is the second largest planet.
• Saturns rings are made of ice, rock, and dust
• On Saturn, it is very cold.
• There are at least forty six moons.
• Takes almost thirty years for Saturn to orbit the
  Sun.
• Rotates in about 11 Earth hours.

Uranus

• Is the seventh planet from the sun.
• It has ten rings.
• the third biggest planet
• It is about 1/3 the size of Jupiter.
• It takes 84 years to make one orbit
• Uranus rotates in about 17 Earth hours.

Uranus
18
Neptune

• Is the eighth farthest planet from the Sun.
• Neptune appears to be blue due to the gas in the
  atmosphere.
• almost the same size as Uranus.
• One Neptune year is 164 Earth years.
• It rotates in about 16 Earth hours.

What are inner planets?

• Inner planets are the small, rocky planets that
• orbit close to the sun.

• What are outer planets?

• Outer planets are the planets that orbit farthest
  from the sun.
