Mercury is the closest planet to the Sun. It is 36 million miles from the
Sun. Mercury is a small dry planet. The side of Mercury that faces the Sun is 932
degrees F. This is hot enough to melt lead. At night it gets very, very cold. As the
planet turns away from the Sun the temperature during the night drops to minus
328 degrees F. Its dusty surface has many big holes. They were made by
asteroids and comets crashing into its surface. Mercury has no air or life on it.
There is no atmosphere to block out the Sun's rays. It has no moons or rings.
Venus is sometimes known as "The Evening Star". Venus is Earth's twin.
Venus is the second planet from the Sun. It is 67 million miles away from the sun.
The core is made of nickel and iron. Venus is the brightest object in our sky.
Venus is 42,000,000 kilometers from the Earth. Venus doesn't have any satellites.
Venus's atmosphere has a lot of carbon dioxide gases in it. It never rains on
Venus because it is too hot for rain to form. It's about the same size as Earth.
Venus's clouds are made mostly of a deadly yellow poison called sulfuric acid.
Earth is the third planet from the Sun. The distance between Earth
and the sun is about 93 million miles. Earth is the only planet that has living
things. All living things need sunlight, water, and certain gases. As we all
know, that Earth has all of these things. There is about three times as much
water on earth as there is land. The Earth spins like a top. One complete spin
is a day. Earth has a protective blanket of air around it called the
atmosphere. The atmosphere is made up of gases like nitrogen and oxygen.
The Earth has one satellite, the Moon. It takes the
moon 27 days and 8 hours to circle Earth. The moon has no
atmosphere, no water, and no sign of life.
The planet Mars is also known as the "Red Planet”. The red planet is the 4th
planet from the Sun. The distance from Mars to the sun is about 143 million miles.
Mars is a very cold, dry planet and is made up of rock which contains a lot of
iron. It’s the iron in the rock and soil that makes the planet look red. Astronauts have
never been able to walk on Mars but they did land space probes on it. The first probe to
land on Mars was in 1976. They were looking for signs of life. Some scientists believe they
found a life form called microbes in the rock samples. There are many volcanoes on this
planet. One very well known volcano on Mars is called Mount Olympus. It is higher than
any volcano on Earth. Mars's diameter is 4,200 miles. The period of revolution for Mars is
687 days.
Mars has two moons named Phobos and Deimos. Mars’s atmosphere is carbon
dioxide.M. Mars’s mass is 1/10th of the Earth’s. Mars’s gravity on the surface is 2/5ths of
the Earth’s. The distance between Mars and Earth is about 34 million.
The word Phobos means fear.
The word Deimos means panic.
Any of the four planets Mercury, Venus,
Earth, and Mars, orbits lie nearest to the Sun. The inner
planets are of similar size and have high densities
compared to the larger gas giants among the outer
planets. They are composed mostly of rock and metal
and are relatively slow to rotate, with solid surfaces,
no rings, and few moons.

The activity that you will be doing today is drawing a
diagram of the four inner plants, Mercury, Venus, Earth and Mars.
Also include then sun. Draw them in order from closest to furthest
from the sun. After your done drawing them, colour them how you
see them in the pictures below. Then when you are done all of this
label some interesting facts about each inner planet beside your
drawing.
Mercury
Venus
Earth
Mars
