How Big Is The Earth?


Look at this picture of the Earth and some of its neighbors. Compared to these worlds, the Earth still looks very large. It is much larger, for example, than Pluto and Mercury, a few times larger than the planet Mars, and just slightly larger than the planet Venus.


Earth's Size Compared To Larger Planets

As we compare the Earth with its larger neighbors, however, we begin to see just how small it really is. The massive gas giant planets of our Solar System are many times larger than the tiny world that we inhabit. Notice the storm that is raging in the clouds on Jupiter. This storm is actually larger than our entire planet.
