Our Solar system

1. Our Solar system Christopher Robles, Angel Aldaco, Travis Gearhart, Emilio Frank, Students, EMPACTS Project Northwest Arkansas Community College, Bentonville, AR

2. Some words to know before we continue • Gravity- force that attracts you or anything to an object with greater mass • Dwarf planet- is a similar to a planet, but is technically too small to be considered one • Orbit-the curved path of a celestial object or spacecraft around a star, planet, or moon • Atmosphere- the area of gases surrounding the earth or another planet • Star- is a massive, bright sphere of gases held together by its own gravity

3. Our galaxy • We live in a galaxy called the milky way • A galaxy is a group of stars and other space stuff (dust, gases, planets) • The stars tend to spin around a center of high gravity, sort of like the planets spin around the Sun in the Solar System • Galaxies are huge and can have trillions (way bigger than billions!) of stars

4. The planets Neptune Uranus Saturn Jupiter Poor Pluto Mars Earth Venus Mercury The sun

5. The Sun • The Sun is a star that is in the center of the Solar System • Our sun is 5 BILLION years old! • It was once just a big area of gas and dust that was condensed by gravity • The Sun’s distance from the Earth is 150 million km (93 million miles)

6. Mercury • On Mercury you weigh only 38% of what you weigh on Earth. • One side of the planet can be 800 degrees Fahrenheit when the other can be -280 degree Fahrenheit at the same time. • Fastest orbiting planet • Planet nearest to the sun

7. Venus • Is the cloudy planet • Venus has tons of volcanos just like earth • Rotates in the opposite direction of Earth • Venus is the hottest planet in the Solar System

8. Earth • The only known planet to have life • The Earth is an oldie but a goodie, scientists think that Earth is about 4.5 to 5 billion years old! • About 70% of earth is water • Approximately 90% of volcanic action happens in our Earth's oceans!

9. Mars • Mars is nicknamed the red planet • It is covered with rust-like dust even the atmosphere is a pinkish red • Mars has many massive volcanoes and is home to Olympus Mons, the largest volcano in our solar system • Unfortunately Mars has no life as we know it so…no aliens

10. Jupiter • Largest planet in the Solar System • Has a Great Red Spot from a storm system that is more than 400 years old • 9 hours and 54 min=1 Jupiter day (shortest day) • Pressure is so great it would crush a spaceship.

11. Saturn • 2nd Largest planet in the Solar System • 95 times more massive than earth. • Saturn has the largest rings of any planet, the rings are made of icy particles and dust • Most moons of any planet in our solar system

12. Uranus • Uranus appears blue-green in color • It’s axis of rotation is tilted 90 degree • Uranus has 27 moons • If you weigh 100 lbs on earth, your weight on Uranus would be 89 lbs • A year on Uranus is equal to 84.01 Earth Years

13. Neptune • Neptune has visual belts of clouds • Just like Jupiter it has storms happening all around the planet • It has a dark blue spot • Neptune is the farthest planet from the Sun

14. Pluto the dwarf planet • It is considered too small to be a planet so it was put in the dwarf planet category • Smaller than Earth’s Moon • If you weigh 100 lbs, your weight on Pluto would be 7 lbs!!! • Since being declassified as a planet, Pluto’s technical name is now 134340
