Imagine you are a travel agent in the next century. an eccentric billionaire asks you to arrange a “guinness book of solar system records” kind of tour. where would you direct him to find the following (use this chapter and appendix f and appendix g):
the least-dense planet
the densest planet
the largest moon in the solar system
excluding the jovian planets, the planet where you would weigh the most on its surface (hint: weight is directly proportional to surface gravity.)
the smallest planet
the planet that takes the longest time to rotate
the planet that takes the shortest time to rotate
the planet with a diameter closest to earth’s
the moon with the thickest atmosphere
the densest moon
the most massive moon
