Some worlds race around their stars in hours; others take centuries. Some are smaller than Earth, while others dwarf Jupiter. Explore NASA’s confirmed exoplanets to discover this variety and see how individual worlds measure up against our own.
Choose a question to explore
Are giant planets always far from their stars? Can small worlds be scorching hot? Which kinds of planets do different detection methods reveal? Explore these patterns, and remember that what we find also reflects what our instruments can detect.
Compares the length of a planet's year with its size. This view is good for seeing why short-period planets and large planets are easier to find.

About the data and missing measurements
This NASA Exoplanet Archive snapshot was refreshed on September 29, 2026. It contains 6,372 planets; 5,972 have radius and orbital-period measurements. This chart shows only planets with usable measurements for both selected axes and matching your filters. A missing value means unknown, not zero.
Logarithmic axes: X (Orbital period). Equal spacing represents multiplication, such as 1 → 10 → 100, rather than equal amounts.
