1. The Solar System The Sun and other planets Done by: Ng Aik Yang (20) 1A1 Science Ace Thematic Studies

2. The Solar System consists celestial objects bound to it by gravity formed from the gravitational collapse of a giant molecular cloud 4.6 billion years ago. consists of the Sun, the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.

3. The Sun Many of the sun in the universe, where each one has its own systems of planets, moons, asteroids, and comets. born in a vast cloud of gas and dust around 5 billion years ago. Surface cooler than atmosphere. Main Source of energy for the Earth. 98% of all matter within the Solar System is found within The Sun.

4. Mercury Closest planet to the Sun. weaker gravitational pull compared to Earth. -If you weigh 70kg on Earth, you would only weigh about 27kg on Mercury. visible to observers on Earth in the night time sky. is made out of a large percentage of heavier elements, mainly iron. does not have a molten core like those of the Earth and Venus.

5. Mercury covered with craters. -created by ions of accidental encounters with asteroids and comets. dead planet -no volcanic activity -no atmosphere -will forever retain its scares. too small and has too little gravity to have held on to an atmosphere. -any gases released from the planet quickly escapes into space.

6. Venus Second closest planet to the Sun About same size as Earth, thus about the same gravitational pull -weigh 70kg on Earth you would weigh 63kg on Venus. Thicker atmosphere than Earth Has similar properties as Earth, just that surface temperature is very high

7. Venus Almost all of Venus' water has evaporated into the atmosphere. This atmosphere effectively traps the Sun's energy causing the surface to burn much hotter than it naturally would. Rotates in the opposite direction as almost all the other planets.

8. Earth Third closest planet from the sun Probably the only source of life in the solar system -many other planets have yet to be fully explored, thus this cannot be proven, yet. Our atmosphere is mainly made up of nitrogen, and consists of other gases such as oxygen, carbon dioxide.

9. Mars Fourth closest planet to the Sun. Weak gravitational pull -weigh 70kg on Earth, will weigh about 27kg on Mars. Used to have water in the liquid state - now water only in frozen state Similar properties to the Earth Has higher mountains, and deeper canyons than any other planet. -largest canyon on Mars would stretch from New York City to Los Angeles Has the largest volcano in the Solar System

10. Jupiter Strong gravitational pull -weigh 70kg on the Earth, on Jupiter you would weigh 185kg. great red spot visible is where a giant storm has been raging for at least 300 years. -storm's super hurricane winds blow across an area larger than the Earth. no solid surface. -under its atmosphere is liquid hydrogen and water

11. Saturn Similar gravitational pull -weigh 70kg on Earth, weigh 82kg on Saturn. rings are 169,800 miles wide, but less thick than a football field. Similar to that of Jupiter, just smaller -under the clouds of methane and helium the atmosphere slowly turns into liquid until it becomes a giant ocean of liquid chemicals.

12. Uranus Stronger gravitational pull compared to Earth -weigh 70kg on the Earth you would weigh 82kg on Uranus. spins on its side. -believed to be because of a strong impacted crash on Uranus last time. Mostly undefined as explorations have yet to be conducted, as Uranus is too far away.

13. Neptune Stronger gravitational pull -weigh 70 pounds on the Earth, would weigh 84 pounds on Neptune. Similar to Jupiter in that has a giant storm, however we are unable to see how long this storm has been occurring.
