2. Mercury: The Closest Planet Katie Shen

3. Mercury Information • Mercury is one of the terrestrial planets, which means that it has a rocky surface. • It is 0.39 AU or 58 million kilometers from the Sun. It is the closest planet to the Sun, so the planet experiences extreme temperature throughout its day. • It is hard to view from Earth, because its solar radiation damages telescope optics. • It is not a likely place to find life because it has almost no atmosphere and no water. • Mercury contains far more metals than the other planet in this solar system. It also has a magnetic field.

7. General Information • It can only be seen near sunset or sunrise, and it is called either a morning star or a evening star. • Thick layers of carbon dioxide compromise Venus's atmosphere. • The atmosphere is very hot containing sulfuric acid. • The atmospheric pressure at the surface of Venus is 90 times the pressure of Earth’s surface atmospheric pressure. • It spins in the opposite direction from other planets and the sun. • It is 0.7 Astronomical Unit from the sun. • It takes 224 days for Venus to orbit the sun.

10. Facts • 4th planet from sun • 1.5 AU from sun • Thin atmosphere • Mostly CO2 • Volcanoes, impact craters and dust storms • Ice caps show evidence of solid and (in past) liquid water. • 1.9 Earth years – revolution • 24.7 Earth hours – rotation • Two moons – Phobos; Deimos

11. Mars’s polar ice caps show a slight possibly for the planet to support life.

12. The 5th Planet: Jupiter Made by Tyler Eston

13. Interesting Facts: Jupiter is the 5th and largest planet in our solar system. It’s a gas giant, with a mass slightly less than one-thousandth of the Sun’s mass. Distance from the Sun: Approximately 5AU. On average, about 465 million miles. • As of now, Jupiter has 63 satellites. • A large hurricane on Jupiter called the Great Red Spot is twice the diameter of Earth. • From Earth, it’s the third brightest object in the night sky (after the Moon and Venus).

19. Uranus • Uranus is a bluish gas giant planet. It is the 7th planet in the solar system. Uranus has 11 rings and 27 known moons. Its atmosphere is composed of hydrogen, helium, and methane. • The methane gives the planet its blue color. • Uranus is 19 AU from the sun, or 1 billion, 780 miles from the sun. • Uranus’ axis has a 97.86 degree tilt. Therefore Uranus is also known as ‘the tilted planet’. • A day on Uranus is around 17 hours.

20. The methane gas on Uranus gives it its bluish color.
