MERCURY • Major Features (craters, canyons, mountains, volcanoes, rings, storms, etc.) -Heavily crated • Early Evolution or history of the planet? -Craters caused by asteroids and comets rained down on Mercury approx. four billion years ago. • Composition of the Planet and it’s atmosphere -Silica, and solid outer crust -no atmosphere • What human technology have we sent to this planet and what have we discovered? • Facts: -Does not have a natural satellite -Smaller than the moon -Looks like our moon
VENUS • Major Features (craters, canyons, mountains, volcanoes, rings, storms, etc.) • Early Evolution or history of the planet -Rotates East to West (Retrograde rotation) • Composition of the Planet and it’s atmosphere. -Made up mostly of carbon dioxide • What human technology have we sent to this planet and what have we discovered? • Facts: -Has no natural satellite -Hottest planet -Takes 243 Earth days to make a rotation
MARS • Major Features (craters, canyons, mountains, volcanoes, rings, storms, etc.) - • Early Evolution or history of the planet. - • Composition of the Planet and it’s atmosphere. -Iron -Thin atmosphere, made mostly of carbon dioxide • What human technology have we sent to this planet and what have we discovered? • Facts: -Red because of the Iron -Mars year = 687 Earth days -Has 2 moons
JUPITER • Major Features (craters, canyons, mountains, volcanoes, rings, storms, etc.) -Has a Ring • Early Evolution or history of the planet. -Red spot is a storm going on for the last 300 years • Composition of the Planet and it’s atmosphere. • What human technology have we sent to this planet and what have we discovered? • Facts: -Rotates faster than any planet -Largest planet -Has 10 hour days
SATURN • Major Features (craters, canyons, mountains, volcanoes, rings, storms, etc.) -It has a Ring • Early Evolution or history of the planet -Ring made up of billion of pieces of rocks, ice, and dust • Composition of the Planet and it’s atmosphere -Titan is the only moon with an atmosphere • What human technology have we sent to this planet and what have we discovered? • Facts: -Lowest density of all planets -60 known satellites - 9 times the size of Earth
URANUS • Major Features (craters, canyons, mountains, volcanoes, rings, storms, etc.) -“The Blue Planet” • Early Evolution or history of the planet -Tilted from the impact of a comet, or another planet. • Composition of the Planet and it’s atmosphere. -Methane Gas • What human technology have we sent to this planet and what have we discovered? • Facts: -Coldest planet in solar system -Tilted completely on its side - Blue from methane gas
NEPTUNE • Major Features (craters, canyons, mountains, volcanoes, rings, storms, etc.) -Dark ring • Early Evolution or history of the planet. • Composition of the Planet and it’s atmosphere. -Hydrogen • What human technology have we sent to this planet and what have we discovered? • Facts: -Has 8 known moons -Stormiest planet -Has a system of a thin dark ring
PLUTO • Major Features (craters, canyons, mountains, volcanoes, rings, storms, etc.) - • Early Evolution or history of the planet. - • Composition of the Planet and it’s atmosphere. -Ice and rock. • What human technology have we sent to this planet and what have we discovered? -Tombaugh has proved that this was not a planet and not a star. • Facts: -Pluto was once thought to be a planet. -Earth is it’s only natural satellite. -Located in the Kuiper Belt.
