Mercury
Mercury can get as hot as 800 degrees.
Mercury can be as cold as 300 degrees below zero.
Mercury was named for the Roman god of commerce.
Mercury is the second smallest planet in our solar system.
Mercury has no moon.
One year on Mercury is only 88 days.


Venus
A year on Venus is 225 days.
One day is 243 days on Earth.
The clouds on Venus are made of sulfuric acid.
Venus rotates east to west.


Earth
We are 93 million miles away from the Sun.
Water covers 71% of Earth.
Earth is the only planet known to have life.
In 5 billion years, a day will be 48 hours long. Unfortunately, that is when scientists expect the Sun to explode.
Day and night occurs because of rotation of the Earth.
a full revolution is 365 1/4 days not just 365 days.
It takes 16 million horsepower to break loose from the Earth's gravitational pull.
Our moon is moving away from the earth at about 3cm per year.


Mars
Space missions to Mars suggest that it once had water.
The canals on Mars are actually an optical illusion and not evidence of life.


Jupiter
One day on Jupiter is only 9 hours and 55 minutes.
The gravity on Jupiter is 2.6 times that of the Earth.
Jupiter has rings just like Saturn

Saturn
The rings of Saturn are made of ice and rock.
Saturn is lighter than water.
It takes Saturn exactly 29.46 years to travel once around the Sun.
Saturn is 75000 miles wide.


Uranus
Uranus is 1.8 billion miles away from the Sun.
One day is 18 hours


Neptune
Neptune is named for the Roman god of the sea.
Neptune has at least 11 moons.
Neptune was discovered in 1846 (over 150 years ago). Since that time it has still yet to make a complete orbit around the sun, because one Neptune year lasts 165 Earth years!


Pluto
Pluto is named for the Roman god of the underworld.
One year on Pluto is equal to 248 Earth years.
Pluto only has one satellite (moon), called Charon and is nearly a planet itself.
Sometimes Pluto is actually closer to the Sun than Neptune is because it has a funny shaped orbit.
Pluto is not a planet, because it does not have a fixed orbit and it's orbit comes in between the orbit of another planet (Neptune).
