Every Object in the Universe by Mass | 3D Size Comparison 2026

HAT-P-67 b is more than twice Jupiter's radius - yet it has less than half Jupiter's mass. Size and mass are not the same thing. This continuous 3D comparison ranks 52 objects by MASS, from the Moon and tiny rocky worlds through gas giants, brown dwarfs, the Sun and R136a1. The spheres are shown with their approximate radii, so the moments when visual size stops matching mass are the point of the film - not an error. How to read the cards: MASS is the quantity that determines the order. Units change from Earth masses to Jupiter masses and then solar masses as the scale grows. RADIUS controls the visible sphere size. A ≈ mark indicates an estimate. DENSITY compares average density with Earth when the required values are available. TYPE identifies the object's broad class. Things worth watching for Kepler-444 d has only one fifth of Earth's mass, but its compact radius makes it denser than Earth. HAT-P-67 b looks much larger than Jupiter while weighing only about 143 Earths; Jupiter is about 318 Earths. Around 13 Jupiter masses, deuterium burning becomes possible and the planet/brown-dwarf boundary gets fuzzy. R136a1 ends the ladder at roughly 291 solar masses in the working dataset. The planetary and stellar surfaces are scientific visualizations and illustrations, not telescope photographs. Values are compiled in the project source sheet; exoplanet rows use NASA Exoplanet Archive composite parameters where available. Masses and radii are estimates that can change as measurements improve.
