- 1. PLANETS OF OUR SOLAR SYSTEM BY: Geenie Choy 8C
- 4. VENUS “ Evening Star” --the clouds covering Venus reflect sunlight easily, allowing Venus to be seem extremely bright The atmosphere contains carbon dioxide and sulfuric acid *acts as a greenhouse— traps heat this causes Venus to be the hottest planet in the solar system R etrogade rotation: when the planet spins in a clockwise direction on its axis. Since Venus has an opposite rotation than the other planets, the Sun would appear to rise in the west and set in the east. It has a longer day than year because one retrogade rotation takes 225 Earth days . This means Venus takes a longer time to spin than revolves around the Sun.
- 5. EARTH Atmosphere: They protect us from harmful solar radiation by absorbing it, and meteors . 23.5 degrees tilt of axis The Earth’s metallic core in the center and its continuous spin on its axis created the magnetic field. Earth’s satellite is the Moon which rotates around it.
- 9. URANUS UNIQUE due to its 98 degrees tilt this caused Uranus to look like it rotates on its side . For known natural satellites, Uranus has 27 . ATMOSPHERE: H ydrogen H elium M ethane
- 11. DWARF PLANETS
- 12. PLUTO THREE MOONS: Charon — half of Pluto, orbits close to the dwarf planet Nix — farther away Hydra — farther away Using the spectoscope they found that Pluto has methane frost and Charon has water frost . Charon is extremely large for a moon (half of Pluto). It is also bluer than Pluto.
- 13. CERES 1 year = 4.6 Earth years Ceres became known as an asteroid in 1802. This was because many other objects orbiting between Mars and Jupiter were named as asteroids. Since Ceres also orbits in the same area, it became known as an asteroid, too. Surface is covered with clay , water ice , and carbonates . This helped differentiate Ceres from the other members of the asteroid belt.
- 14. ERIS O riginal name: Xena , referring to the popular television show during the time Eris was found I t takes 557 years for Eris to make one orbit around the Sun. MOON: Dysnomia — the daughter of Eris, cause of lawlessness It was not named a planet because Eris did not clear its path of orbit , which meant it didn’t meet one of the requirements for a planet. Dysnomia
