3. SUN Next Back

4. SUN The sun is 92,955,820 miles from the earth The sun is the largest object in our solar system. You could fit more than a million earths inside of the sun. The surface of the sun is called the photosphere, which is 10,000° Farenheit. The temperature of the sun’s core is 27 million° Farenheit! That’s really hot. Next Back

5. SUN The sun is one of just over 100 billion stars. The sun is the closest start to earth. Without the sun, earth would not be able to support life. The sun is 92% Hydrogen and 8% Helium It is 4.6 billion years old. BackNext

6. Mercury Next Back

7. Mercury The closest planet to the sun. Since it is so close to the sun it can get up to 800°F during the day. But at night can drop to -280°F. Mercury has no atmosphere, but has a thin exosphere. The surface of Mercury is like the surface of the moon. Next Back

8. Mercury Mercury is the smallest planet in our solar system. Mercury is the second densest planet. Earth is the densest. It orbits the sun every 88 days One day on Mercury is equal to 176 Earth days. First spacecraft to reach Mercury was Mariner 10. Next Back

9. Venus NextBack

10. Venus Venus and Earth are similar in size, mass, density, composition, and distance from the sun. Venus’s atmosphere is mainly carbon dioxide with clouds of toxic sulfuric acid. The thick atmosphere traps heat, creating temperatures of over 800°F. NextBack

11. Venus One day on Venus is 117 Earth days. The sulfuric acid in the atmosphere is responsible for major surface erosion. The surface of Venus has many volcanoes. Next Back

12. Earth Next Back

13. Earth Earth is the only planet capable of sustaining life. Has a complex atmosphere to protect us from space. The seasons on Earth are the result of the rotation of Earth’s axis around the sun. The diameter of the Earth is 7,926 miles. NextBack

14. Earth One day on Earth is 24 hours and one year is 365 days. Is over 5 billion years old. 70% of the Earth’s surface is water. From space, Earth is the brightest planet, because the sun reflects off of the water. Earth has complex weather patterns. Next Back

15. Mars Next Back

16. Mars Mars is about ½ the size of earth. Mars appears to be red because it’s surface is comprised of iron-rich minerals, which is basically rust. Has no magnetic field, but the surface might be magnetized. Has two small moons, Phobos and Deimos. Next Back

17. Mars Like Earth, Mars has seasons. The cold temperatures and thin atmosphere do not allow for water to exist for long. Scientists are trying to figure out if Mars has ever been home to life. A day on the planet Mars is 7.65 hours, compared to Earth’s 24 hours. Next Back

18. Jupiter Next Back

19. Jupiter Jupiter is the largest planet in our solar system. The stripes are actually swirling clouds, such as the big red spot, which has been raging for over hundreds of years. The clouds are mainly made of ammonia. There is water, but is much deeper than the ammonia. NextBack

20. Jupiter The atmosphere of Jupiter is similar to the atmosphere of the sun. The surface of Jupiter is covered by an ocean of hydrogen with a sludge-like texture. A day on Jupiter is only 10 hours long, because Jupiter rotates so quickly. The mass of Jupiter is 70% of the total mass of all of the other planets in our Solar System. NextBack

21. Saturn Next Back

22. Saturn Galileo was the first to look at Saturn. Hydrogen is mainly made up of mostly hydrogen and helium. The volume of Saturn is 755 times greater than that of the planet Earth A person on Earth who weighs 100 pounds would weigh 116 pounds on Saturn. Next Back

23. Saturn The very fast winds along the surface, combined with heat rising from within the planet’s interior create the yellow and gold bands visible in the atmosphere. Saturn has such a low density that it could float in water. Saturn’s rings are made up of rocks and dust. It takes 29 ½ Earth years for Saturn to orbit the sun. NextBack

24. Uranus Next Back

25. Uranus Uranus was discovered in 1781 by William Herschel, which was the first planet found with a telescope. It takes Uranus 84 Earth years to complete one orbit around the sun. Uranus gets its blue color from the Methane Gas in it’s atmosphere. NextBack

26. Uranus Uranus has a mass more than 14 times larger than the Earth. After Saturn, Uranus is the second least dense planet. Uranus is the coldest planet in the solar system. Because of the way it spins, nights on parts of Uranus can last for more than 40 years. NextBack

27. Neptune NextBack

28. Neptune The last planet in our solar system. It takes 165 Earth years to orbit the sun. More than 2.8 billion miles from the sun. Neptune gets its blue color from methane gases in its atmosphere just like Uranus. Neptune’s “Great Dark Spot” is larger than the Earth NextBack

29. Neptune Neptune has 6 rings Neptune is the stormiest planet in our solar system and winds can blow 3 times faster than Earth’s hurricanes. Neptune is 30 times farther from the sun than Earth. Has 8 moons NextBack

The student knows there are recognizable patterns in the natural world and among objects in the sky. The student is expected to: (A) observe, measure, record, and compare day-to-day weather changes in different locations at the same time that include air temperature, wind direction, and precipitation; (B) describe and illustrate the Sun as a star composed of gases that provides light and heat energy for the water cycle; (C) construct models that demonstrate the relationship of the Sun, Earth, and Moon, including orbits and positions; and (D) identify the planets in Earth's solar system and their position in relation to the Sun.
