Zoom out from an average adult to Jupiter

Jupiter is too big to show next to an average adult in one picture, so here it is in 9 steps. Each step is drawn to its own scale and zooms out from the step before.

  1. Step 1 of 9 Human → Megalodon

    A megalodon is about 8.6–15 times as long as an average adult is tall.

About Jupiter

Jupiter is the largest planet in the Solar System, a gas giant orbiting at an average of about 778 million km from the Sun. NASA's Planetary Fact Sheet gives an equatorial diameter of 142,984 km, measured at the level where the atmospheric pressure is 1 bar, about 11 times Earth's. Its mass of about 1.9 × 10²⁷ kg is nearly 318 times Earth's, and its fast spin flattens it noticeably at the poles.

  • Jupiter has 317.83 times Earth's mass and 1,321.33 times its volume. [1]
  • A day on Jupiter lasts 9.9259 hours, the shortest of any planet, and a year lasts 4,332.589 Earth days. [1]
  • Jupiter's polar radius (66,854 km) is about 4,600 km less than its equatorial radius, a flattening (ellipticity) of 0.06487. [1]
  • NASA's fact sheet lists 95 natural satellites for Jupiter. [1]

How many fit?

  • ≈ 85 million × Human · height lined up end to end match the Jupiter · equatorial diameter
  • ≈ 2.3 × 10²⁵ × Human · body mass on the scales weigh as much as Jupiter · mass
  • ≈ 41 × Moon · diameter lined up end to end match the Jupiter · equatorial diameter
  • ≈ 26,000 × Moon · mass on the scales weigh as much as Jupiter · mass
  • ≈ 65,000 × Moon · volume packed inside, by volume fill Jupiter · volume

Counts divide one sourced figure by another. "End to end" uses each object's main measurement; weight and volume rows appear only when both figures are sourced.

How it compares

Factors compare the equatorial diameter of Jupiter with each object’s own main measurement (height for a human). Where a size varies, the factor is given as a range.

Notes on these figures

  • Jupiter has no solid surface; its radius and diameter are measured at the 1 bar pressure level in its atmosphere.
  • The moon count reflects the fact sheet on the access date and changes as new moons are confirmed.
