Document Summary
Comparative planetology: when we compare the worlds to one another, seeking to understand their similarities and differences. We can learn more about an individual world, including our own earth, by studying it in the context of other objects in our solar system. Sun: the largest and brightest object in our solar system, contains 99. 8% of the solar system"s total mass which makes it nearly a thousand times as massive as everything else in the solar system combined. Solar wind: charged particles flowing outward from the sun that help shape planetary magnetic fields and influence planetary atmospheres. Mercury: has hot and cold extremes because of tidal forces from the sun that force it into an unusual rotation pattern. Its surface is heavily cratered and shows evidence of past geological activity, such as plains created by ancient lava flows and tall, steep cliffs that run hundreds of kilometers in length.
