Document Summary
All of the planets were formed around the same time ( - 4. 7bya) They are formed from the same materials - but in differing percentages. All planets move counterclockwise around the sun in elliptical orbits. Terrestrial planets the moon and mercury venus mars hard surfaces earth moon small, no atmosphere, hydrosphere or biosphere. each is covered with craters which record the birth of the solar system - 4. 7bya. Very hot and thick clouds, atmosphere is very acidic and it has a very strong greenhouse gas effect. Huge canyons and volcanoes, strong dust storms, ice caps and dry riverbeds. It is about 1/2 the diameter of earth and venus but twice the size of mercury. Jupiter- largest of the planets and most complex, it emits more energy than it gets from the sun. It has a small rocky core, 16 moons and a faint ring. It is similar to a mini solar system, and it does not tilt.
