Out planet Earth takes 365 days to go around the sun. The planet Pluto takes almost 248 years! The planet Jupiter is so big that if it were a large, hollow ball, over 100 Earths could fit inside. The planet Mercury is so hot that plants and animals cannot live on it–they would burn up.
Here is a very simple and accurate introduction to our solar system and to the nice planets that go around our sun. Franklyn M. Branley's clear and lively text, which includes instructions for making two models (one that shows the relative sizes of the planets and the other their relative distances from the sun), is illustrated with close-up photographs, and sprightly drawings by Don Madden.
