Planet Size Comparison
Scroll horizontally to journey from the smallest worlds to the largest. This visualization renders every body at true proportional scale, letting you grasp just how vast the size differences are across our solar system.
← Back to visualizationsHow to explore
- Scroll or drag horizontally to pan through the size scale.
- Start with the smallest bodies on the left—Pluto and the Moon.
- Watch the scale transform as gas giants and the Sun come into view.
- The info panel shows the current body's radius and Earth comparison.
True-to-scale radii
Every celestial body renders at its actual proportional size—no exaggeration or artistic license.
Scroll to zoom out
Pan from left to right to reveal increasingly massive bodies, from Pluto to the Sun.
Size comparisons
Live ratios show how many times larger each body is compared to others in view.
Rich details
Surface features like Jupiter's Great Red Spot, Saturn's rings, and Earth's continents are visible at larger scales.
Data & scale
All radii use equatorial measurements in kilometers. The Sun's radius of 696,340 km is roughly 109 times Earth's, and about 9.7 times Jupiter's. Pluto, the smallest body shown, could fit inside the Sun over 200 million times.
The visualization maintains true proportions throughout—what you see is an accurate representation of relative sizes, not an artistic interpretation.
