Solar System Explorer
The Sun and eight planets. Select a planet for its key facts.
Illustrative view — planet sizes and distances are not to scale (real scale would make planets invisible). Orbital speed is compressed for viewing.
Earth
Our home: the only known planet with liquid-water oceans, an oxygen-rich atmosphere, and life. Its axial tilt drives the seasons.

Model assumptions
Illustrative only: sizes, distances and speeds are compressed so everything fits on screen. Real scale would make planets invisible dots.
