 There are eight major planets in the solar system, all with their own unique features.  This power point will explain how each of these planets differ.

 Mercury is the innermost and smallest planet of the solar system  It’s diameter is km  It’s temperature ranges from - 173° C to 427° C  The atmosphere consists of some hydrogen, helium, and oxygen  There is no wind, no rings, and no moons on mercury  It’s average distance from the sun is 57,910,000 km  Mercury’s rotation lasts 58 Days, 15.5 Hours  It has an iron core, and a silicate surface  Mercury has a slight magnetic field

 Venus is the second planet from the sun  It is the hottest and brightest planet  It’s diameter is 12,104 km  The temperature ranges from -45° C to 464° C  It’s atmosphere consists of nitrogen and 97% carbon dioxide  Venus has no moons and no rings  It’s distance from the sun is 108,200,000 km  It’s retrograde rotation lasts 243 Days, 0.5 Hours  Like Mercury, Venus has an iron core and a silicate surface

 Earth is the third planet from the sun  It’s 4.6 billion years old and the fifth largest planet in our solar system  Earth has an average diameter of 12,742 kilometers.  It’s average temperature is between 5000 and 7000 degrees C.  The Earth is made mostly of iron, oxygen, silicon, magnesium, nickel and sulfur

 Mars is the fourth planet from the sun  Diameter is km  Temperature ranges from -140° C to 20° C  Mars has a very thin atmosphere, made mostly of carbon Dioxide  Mars has large canyons, volcanoes, dust storms, sand dunes, polar ice caps and other features similar to those found on Earth.  It has two moons and winds up to 100 km/hr  It’s 227,940,000 km from the sun  Mars is composed of Iron Oxides and Silicates

 Unlike the rocky planets, Jupiter is a ball of dense hydrogen, helium, water, nitrogen and other gases over a tiny rocky core.  It’s diameter is 142,984 km  It’s temperature ranges from -163° C to >-121° C  Jupiter's atmosphere is made up of Hydrogen, Helium, Methane  It has winds up to150 m/s and over sixty moons  The average distance from the sun is 778,330,000 km and it’s rotation only takes hours  Jupiter has three rings

 Saturn’s diameter is 120,536 km  It’s temperature ranges from -191° C to >-130° C  Like Jupiter, Saturn’s atmosphere is made up of hydrogen, helium, and methane  There are winds up to Up to 400 m/s and a total of 31 moons  Saturn has rings and is composed of hydrogen and helium  It has an extremely strong magnetic field

 Being the seventh planet from the sun, the icy planet Uranus is a smaller version of Jupiter  Uranus takes about 84 years to orbit the sun while rotating on its side  The faint bluish color of the planet is because the methane gas in the atmosphere absorbs red light and reflects blue light.  It’s diameter is 51,118 km  Uranus has sixteen moons and is 2,870,990,000 km away from the sun

 Neptune is the eighth and farthest planet from the sun  Its diameter is 49,572 km  Its temperature ranges from -223° C to >-220° C  It has rings and thirteen known moons  Neptune’s magnetic field is up to 20 times its radius  Neptune is one of the solar system's gas giants

 Our Solar System is a mysterious, beautiful thing.  The eight planets in our Solar System are all different and have their own story to tell.  I hope one day we will be able to travel to these other planets and find new incredible facts about our Solar System.
