Start here: main parts 6

  1. Great Red Spot A giant oval storm, bigger than Earth.
  2. Equatorial Zone The band of cloud along Jupiter's equator.
  3. North Equatorial Belt The belt just north of the Equatorial Zone.
  4. Core A core with no sharp edge, called dilute or fuzzy.
  5. Ganymede The largest moon in the solar system, bigger than Mercury.
  6. Rings Faint rings of dust, hard to see except when backlit.

The face 4

  1. South Equatorial Belt The belt just south of the Equatorial Zone.
  2. North Tropical Zone The zone north of the North Equatorial Belt.
  3. South Tropical Zone The zone south of the South Equatorial Belt. The Great Red Spot lies in it.
  4. North polar region The area around Jupiter's north pole.

Inside 3

  1. Cloud layer The thin outer skin of clouds. The belts and zones are its top.
  2. Molecular hydrogen Hydrogen as a gas, squeezed into a liquid with depth.
  3. Metallic hydrogen Hydrogen squeezed so hard it conducts electricity like a metal.

Moons and rings 3

  1. Io The closest of the four large moons. It has hundreds of volcanoes.
  2. Europa The smallest of the four. An ocean may lie under its icy shell.
  3. Callisto The outermost of the four, and heavily cratered.

How this list was compiled: Every name and fact checked on 2026-10-03 in two independent sources, NASA and Wikipedia. (1) NASA Science, Jupiter Facts, https://science.nasa.gov/jupiter/jupiter-facts/ (belts and zones, the Great Red Spot, cloud layers, hydrogen gas compressed into a liquid, liquid metallic hydrogen, the dilute or fuzzy core, the rings, the four largest moons), with the pages of the four moons under https://science.nasa.gov/jupiter/jupiter-moons/ (Io's volcanoes, Europa's ocean under an icy shell, Ganymede the largest moon, Callisto heavily cratered; the order of the four by size). (2) NASA/JPL Photojournal captions, read through https://images-api.nasa.gov : PIA24236 (North Equatorial Belt, North Tropical Zone), PIA22950 and PIA24235 (South Equatorial Belt, South Tropical Zone, the Great Red Spot at that latitude), PIA00456 (the equatorial zone), PIA20895 and PIA22945 (north polar region), PIA25062 (an outer envelope of molecular hydrogen over metallic hydrogen), PIA00601 and PIA01400 (in order of increasing distance: Io, Europa, Ganymede, Callisto).

How it works

Jupiter labeled in three views: the belts, zones and Great Red Spot on its face, the layers inside, and the four large moons with the rings. Read the names, then press Quiz me or print it blank.

The face

North is at the top. The stripes are clouds. On the real planet the darker ones are called belts and the lighter ones zones. The Equatorial Zone runs across the middle, with an equatorial belt and then a tropical zone on each side. The Great Red Spot is a giant storm in the southern half.

Inside, then the moons

Jupiter has no true surface. Under a thin layer of clouds, hydrogen gas is squeezed into a liquid, and deeper still into liquid metallic hydrogen. The core has no sharp edge. Of the four large moons, Io is the closest, then Europa, Ganymede and Callisto. The rings are thin and faint.

Questions and answers

What are the stripes on Jupiter called?

The dark stripes are called belts and the lighter bands are called zones. They are clouds, and they flow east and west in opposite directions.

What is the Great Red Spot?

The Great Red Spot is a giant storm in Jupiter's southern half, bigger than Earth. It lies in the South Tropical Zone, on the edge of the South Equatorial Belt.

What is inside Jupiter?

Mostly hydrogen and helium. Below the clouds the hydrogen gas is compressed into a liquid, and deeper down into liquid metallic hydrogen. The core is partly dissolved, with no clear edge.

What are Jupiter's four largest moons?

Io, Europa, Ganymede and Callisto, in order of distance from Jupiter. Galileo first saw them in 1610. Ganymede is the largest moon in the solar system.

Does Jupiter have rings?

Yes. Jupiter's rings are faint and made of small, dark particles, so they are hard to see except when the Sun lights them from behind.
