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 turn parts of that scale into curated essays, while focused views let you explore the same range through specific groups of objects.

Planets

Saturn

Saturn is a gas giant best known for its bright ring system, but the planet itself is also the least dense world in the Solar System. Its average density is lower than water, and its layered atmosphere is driven by powerful winds and storms beneath the rings that dominate its silhouette.

Stars

Sun

The Sun is the star at the center of the Solar System and the engine behind every climate and orbit within it. It fuses about 600 million metric tons of hydrogen each second, while photons created in the core can take roughly 250,000 years to work their way to the visible surface.
