Do Now 10/28/13. 1) How many planets do we have in our solar system? 2) How was our solar system formed?. 8 Mercury, Venus, Earth, Mars, Jupiter, Saturn Uranus, Neptune – Pluto is now considered a dwarf planet.
8 Mercury, Venus, Earth, Mars, Jupiter, Saturn Uranus, Neptune
– Pluto is now considered a dwarf planet
The Nebula Theory - A supernova condensed a nebula cloud, forming out sun, then our solar system
2) Which Planet has iron Oxide in its soil?
3) Which planet is 800°F during the day and -290° at night? WHY?
Covered in craters because no atmosphere to protect it
Mercury-extremely thin atmosphere cannot retain heat
Only planet to have life, has ozone, protective atmosphere, plate tectonics, strong electromagnetic field
Its rotation – 243 days (24hrs is ours) is longer than its revolution - 224 (365 days is ours)
The sun rises in the west and sets in the east
No because it is so close, the solar winds blast it away
Reddish color due to iron oxide, atmosphere is mostly co2, thought to have had water at one time, 4th planet from the sun, smaller than earth, has a mountain larger than Everest, has a canyon bigger than the grand canyon
Rock, dust, ice
Its reverse from all other planets, retrograde movement
Revolution is the time it takes for the object to go around the Sun and orbit is the path that the objects follow to go around the Sun
Because of Pluto’s elliptical orbit
Carbon dioxide ice
2) What is the turning on an axis called?
3) Which dwarf planet is a large, round asteroid?
Triton, Neptune’s largest moon
FIVE- Ceres, Pluto, Eris, Makemake, Haumea
1) Which is the largest moon in our solar system?
2)Which planets/moon have H2O water in all three phases (solid, liquid, gas)?
3) What is an object that gets caught in the gravitational pull of a planet?
Mercury, Venus, Earth, Mars : inner planets, rocky
Mercury – 0 Jupiter - 63
Venus – 0 Saturn – 55
Earth – 1 Uranus – 27
Mars – 2 Neptune - 14
The excessive amount of CO2, causes the greenhouse effect to be extremely strong, all the hear from the sun is kept on the planet and cannot escape back into space
