write a micro-theme on the solar system and the interrelationships between the earth, the sun, and the planets.

Called solar system because Sun is biggest and heaviest

Solar means sun  planets revolve about (travel in circles around) the sun  path a planet travels is called its orbit  earth is the 3rd closest planet to the sun  all the planets go around in the same direction (like clockwise or counterclockwise), in roughly the same plane, but at different speeds  planets close to sun move fast, far out move slower  closer a planet is to the sun, the hotter it is, more or less.
