See the answer Which of the terrestrial planets is the largest? Scientists were surprised that TRAPPIST-1e is the only planet in the system slightly denser than Earth, suggesting it may have a denser iron core than our home planet. The planet has an equatorial radius of 7,514 miles, which is less than that of the Earth. Terrestrial planets also have a molten heavy-metal core, few moons and topological features such as valleys, volcanoes and craters.

A planet is defined as a body that revolves around the Sun, is large enough to be rounded by its own gravity, and has cleared its orbit of smaller objects. As we continue checking off items on the habitability list, we'll draw closer and closer to finding a world bearing recognizable signs of life. In our solar system we have eight planets: Mercury, Venus, Earth, and Mars are the inner rocky or "terrestrial" planets.
