3. The Sun • The Sun’s core is around 13,600,000 degrees Celsius! • The Sun is a star found at the center of the Solar System • Light from the Sun reaches Earth in around 8 minutes. • The sun contains 99.85% of the mass in the solar system. • The sun is the closest star to Earth. • The Sun has a very strong magnetic field. • The Sun is 109 times wider than Earth, and is 333,000 times heavier. • In ancient times, people believed the Sun was a burning ball of fire created by the gods. • Over one million Earths could fit inside the Sun.

4. Mercury • The surface of mercury looks just like our moon. It has a very rocky surface covered with a lot of craters. • There is also no water on the surface of Mercury, but there could be underneath the surface • Mercury is the closest planet from the sun • Mercury’s dark side is very cold but the other side is scorching hot! • It is 57 million miles away from Earth. • It can be seen in the nigh sky without a telescope. • The sun looks two and a half times larger in Mercury's sky compared to the Earth's. • Because of the shortage of atmosphere, Mercury's sky is black and the stars probably can be seen during the day.

5. Venus • Venus is the hottest planet in our solar system. • Venus is often called the Earth’s sister planet because they are almost the same size. • Venus is the second brightest object in the night sky. • The surface of Venus is often described as a "stormy desert" full of many craters and active volcanoes. • And it takes 224 days for Venus to orbit around the sun. • Venus rotates counter-clockwise. • Venus is the second planet from the Sun.

6. Earth This is earth This planet is the only planet with… • Earths is smoother than a bowling ball • 14% of the worlds species have not been identified • From a distance, Earth would be the brightest of the planets. This is because sunlight is reflected off the planet's water. • It has one moon (Luna). • Earth is almost five billion years old. • Earth has natural disasters such as tornados, hurricanes, earth quakes, tsunamis, and volcano eruptions.

8. Mars Mars • Mar’s red color is actually iron oxide , also known as rust . • There is a rock formation on mars that looks just like a human face. • In winter, nighttime temperatures on Mars can drop as low as -191°F. • Valleys and Canyons on Mars suggest that the planet once had large amounts of surface water. • Mars has the tallest volcano in the solar system. Its is 15 miles high which is three times the size of Mount Everest. • A 100 pound man would way 38 pounds on Mars • Mars has a rover (know as Curiosity) it has done many things such as finding mars suitable for life, finding evidence of water, and not finding methane in the air. These things are just one of many discoveries curiosity has found.

9. Jupiter • Jupiter is the fastest rotating planet in our solar system ,it rotates so quickly that the days are only 10 hours long. • Jupiter has 63 moons, Jupiter's moon, Ganymede, is the biggest moon in the Solar System. • Jupiter's Red Spot is in fact a storm the size of Earth that has raged for hundreds of years. • Jupiter is around 11.1 times larger than Earth, so about 1,367 Earths would fit inside Jupiter.

10. Saturn • Saturn's rings are made up of billions of pieces of rocks and dust. • Saturn has the lowest density of all the planets in the solar system. • Saturn is the second largest planet in the Solar System other than Jupiter. • It is mostly made up of hydrogen and helium gas. • Saturn's rings are the only ones that can be seen from Earth. • A day on Saturn is 10 hours. • The day Saturday was named after the planet Saturn. • Winds around the equator can be 1,800 kilometers per hour

11. Uranus • Is the coldest planet in the Solar System. • Uranus orbits the sun on it side. • Uranus has rings. • Uranus’ moons are named after characters created by William Shakespeare. • The only spacecraft to visit Uranus is Voyager 2. • Nights on some places on Uranus can last for more than 40 years. • It takes 30,685 Earth days for Uranus to complete an orbit around the sun. • Uranus is also know as an ice giant. • Uranus has 27 moons.

12. Neptune • Neptune is the farthest planet from the sun. • Neptune has the strongest winds in the Solar System. • Neptune is the coldest planet in the Solar System. • Neptune’s moon Triton is even colder than the planet. • It took the space probe Voyager 2, 12 years to reach it. • Neptune has 19 moons. • It goes around the sun once every 165 years. • The planet Neptune was discovered on Sept. 23, 1846 .
