WebbVenus is one of the four terrestrial planets in the Solar System, meaning that it is a rocky body like Earth. It is similar to Earth in size and mass and is often described as Earth's "sister" or "twin". The diameter of Venus is 12,103.6 km (7,520.8 mi)—only 638.4 km (396.7 mi) less than Earth's—and its mass is 81.5% of Earth's.

Then comes Venus and Earth, both with a diameter of 2 cm, followed by Mars (diameter a little over 1 cm). These are the four inner or rocky planets modeled with play dough. The next four planets are much larger, they are the gaseous planets and are modeled by balloons. chrystal mccloud
