Earth is the largest of the four rocky planets and the only world known to host life. Liquid water has covered most of its surface for billions of years, shaping both its geology and its atmosphere.
Scale Comparison
The Sun spans about 109 Earth diameters and contains more than 99.8% of the Solar System’s mass.
About 1.3 million Earth-sized volumes would fit inside the Sun. The Sun is a plasma sphere powered by core fusion, so the comparison crosses from a rocky planet to a star rather than showing two versions of the same kind of body.
Objects
Object details and sources
The Sun is the star at the center of the Solar System and the source of almost all the energy reaching its planets. It fuses about 600 million metric tons of hydrogen each second, and energy released in the core takes on the order of 100,000 years to work its way out to the visible surface.

About
Scale of Space is a scroll-based journey through the universe, placing objects on a single logarithmic scale so you can compare size across an unbroken range.
Guides explain selected parts of that range, while focused views filter the objects by subject.
