Week 3 Day 1 Question of The Day Answer: B

Week 3 Day 1 Mars small planet 4th planet from Sun orbit is mild ellipse or stretched circle named after the Roman god of war year is 687 Earth days day is 24 hr. and 37 min. diameter 6800 km. Can be seen without a telescope—a small rust colored light in the sky

Mars core of iron thick rock layer above core atmosphere thinner than Earth’s has dust storms and clouds entire planet can be covered by storms and dust at once average temp. -12 degrees C winter can get to -70 degrees C

Mars In winter, the planet has ice caps at the north and south poles like Earth does. caps are made of frozen carbon dioxide, or “dry ice”. has mountains, sandy deserts and many, inactive volcanoes. largest volcano in the solar system- Olympus Moons- over 133000 m. tall, much higher than Mount Everest, and is over 965 km. wide at its base. many canyons -Valles Marineris- over 3200 km. long and deep enough to hold a mountain range.

Mars two moons- Phobos and Deimos Moon actually asteroids that got caught in Mars’ gravitational pull

Week 3 Day 2 Question of The Day Answer: C

Week 3 Day 2 Jupiter a gas giant 5th from the Sun 1st gas planet in solar system orbit is nearly circular The Romans named Jupiter after the supreme god in their religion. largest planet year=almost 12 Earth yr. day=10 hr.

Jupiter For size comparison, if Earth was a dime….Jupiter would be a soccer ball! can be seen without telescope a giant cloud made up mostly of hydrogen and helium. gravity holds this ball of gas together does not have surface since it is gas Constant swirling of gas creates wind storms—Great Red Spot At least 16 known moons

Jupiter 3 largest moons--Europa , Callisto , Ganymede Europa is a giant ball of ice. Callisto is covered with thousands of craters Ganymede, the largest moon, is made up of rocky ice.

Saturn mostly hydrogen and helium less dense than Jupiter no solid surface center=liquid hydrogen at least 18 moons most interesting moon=Titan Titan=thick atmosphere containing nitrogen Titan may have liquid water on surface

Saturn Special Features The Rings  Very thin seem to disappear when Saturn is viewed from the edge made up of billions of snowballs, ranging from the size of a cricket ball to bigger than a house. The gaps in Saturn’s rings are caused by the many moons that circle the giant planet. The moons keep the rings lined up. One of the bands in Saturn’s rings is braided, much like a pigtail.

Saturn Special Feature Weight weighs very little very light gas planet so light that it could float in water.
