FC: Our Solar System As we know it...

1: Created by: Marcus Bruce

2: Mercury is the closest planet to the sun. It averages a distance of 57 million km from the sun. Its diameter is 3,031 miles; 2/5 the Earth's diameter. Ancient Romans named it Mercury in honor of the swift messenger of their Gods. Mercury has no moons. If you weigh 100 pounds on Earth, you would only weigh 37 pounds on Mercury. It takes less than 88 Earth days for Mercury to orbit around the sun. It rotates slowly on its axis and completes one rotation every 59 Earth days. As a result, the interval between one sunrise and the next—lasts about 180 Earth days. Mercury can reach temperatures of 800+ degrees. It is much too hot to sustain life.

3: Our wedding day has finally come... | Mercury

4: Venus

5: Venus is the second planet from the sun and the closest planet to Earth. It averages 108 million km from the sun. It is named after The Roman Goddess of love and beauty. The diameter of Venus is about 7,520 miles which is about 400 miles smaller than that of Earth. Venus is known as Earths' twin sister because of its similar size and proximity to each other. Venus rotates so slowly that it orbits the sun faster than it can make one whole rotation on its axis. In other words, Venus has a longer day than year. It takes 243 days for Venus to make a rotation and it takes 224 days for Venus to orbit around the sun. Some scientists believe Venus can sustain life.

6: I'm so happy I can finally call this man my husband. It's really a dream come true

7: The Earth, sometimes called the 3rd Rock From The Sun, is estimated to be 4.5 billion years old. It averages 150 million km from the sun. It travels through space at 660,000 miles per hour. The Earth weighs 6,588,000,000,000,000,000,000,000 tons. The earth rotates on its axis more slowly in March than in September. The temperature of the Earth's interior increases by 1 degree every 60 feet down. Glaciers occupy 5.8 million square miles, or 10 percent of the world's land surface, an area as large as South America. The world is not round. It is an oblate spheroid, flattened at the poles and bulging at the equator.

8: Mars

9: Mars is the 4th closest planet to the sun. It averages 228 million km from the sun. Mars is the only planet whose surface can be seen in detail from the Earth. It is reddish in color, and was named after the bloody red God of war of the ancient Romans. Mars is red because it is rusty. There is a lot of iron in the soil, and the air on Mars has made it turn red. One of Mars' moons, Phobos, is moving closer and closer to Mars. Scientists think that one day it will crash into Mars. A hundred pound man would weight 38 pounds on Mars. Mars orbits the sun every 687 Earth days. It's debated whether or not Mars can sustain life. It has water, but it's surface gets too hot during the day and too cold at night. Also, its surface has too much salt which isn't conductive of sustaining life.

10: Jupiter

11: Jupiter is the largest planet in our Solar System and the 5th planet from the sun. It averages 779 million km from the sun. It was named after the king of the Roman Gods. If you weigh 100 pounds on Earth, you would weigh 264 pounds on Jupiter. Jupiter rotates faster than any planet in the Solar System. It rotates so quickly that the days are only 10 hours long. The great red spot on Jupiter is a storm that has been going on for over 300 years. You can fit 100 Earths into Jupiter's great red spot. Unlike other planets, Jupiter sends out a strong radio radiation that can be detected on Earth. Jupiter cannot support life because it has no atmosphere. The pressure is really strong so anything that enters its atmosphere would be crushed.

12: Saturn

13: Saturn is the 6th planet from the sun. It averages 1.43 billion km from the sun. It is the second largest planet. It has 7 thin, flat rings around it. Saturn's diameter at its equator is 74,600 miles which is almost ten times that of Earth. The planet can be seen from Earth with the unaided eye, but its rings cannot. They named Saturn after the Roman God of agriculture. A 100 pound object on Earth would weight 116 pounds on Saturn. It takes about 29.46 Earth years for Saturn to orbit around our sun. Saturn has no solid surface. It is a giant ball of gas, but it does have a solid inner core. Saturn can't support life because it has no oxygen and has poisonous gases in which no life can survive.

14: Uranus

15: Uranus is the seventh planet from the sun and is named after the Greek God of the sky in Latin. It averages 2.88 billion km from the sun. Because of the strange way it spins, nights on some parts of Uranus can last for more than 40 years. Even though Neptune is further from the sun, Uranus is the coldest planet in the solar system. Uranus mass is more than 14 times larger than Earth. It takes 30,685 Earth days for Uranus to complete an orbit around the sun. You can see Uranus with the unaided eye. Uranus has only been visited once. Uranus has no solid surface. It's mostly composed of ices: methane, water and ammonia. It is also extremely cold on its surface. The inside gets warmer towards the core, but there is too much pressure which would crush any life forms. Also there is no sun underground.

16: After Pluto was declassified as a planet, Neptune became the farthest planet from the sun. It averages 4.5 billion km from the sun. Neptune's diameter is about 30,200 miles or almost 4 times the Earth's diameter. The planet was named after the Roman sea God. Neptune is so far away that it took the space probe Voyager 2, 12 years to reach it. Neptune is the stormiest planet. The winds there can blow up to 1,240 miles per hour, that is three times as fast as Earth's Hurricanes. Neptune has its own heat source, it emits a quantity of energy 2.7 times greater than it receives. Some scientists believe there is a slight chance that Neptune could support life. Although there is no visible water on the surface, some believe there may be some underground. However, its atmosphere is made up of too many gases and not enough solids. So it is debatable whether or not it can sustain life.
