Planet 05 · Gas giant
A failed star's worth of weather without the failed-star cliché.
Jupiter is the solar system's largest planet, a hydrogen-helium world whose gravity has redirected comets, accelerated spacecraft, and shaped the architecture of everything around it. Its cloud tops hide liquid and metallic hydrogen around a diffuse heavy-element core.
World profile
Mostly hydrogen and helium with ammonia, ammonium hydrosulfide, and water cloud layers.
No solid surface; gas compresses into liquid and then electrically conducting metallic hydrogen.
Cloud tops average about −166 °F (−110 °C)
A vast system led by Io, Europa, Ganymede, and Callisto
Composition
Field notes
Jupiter contains more than twice the mass of every other planet combined.
The Great Red Spot is a centuries-old storm that extends more than 200 miles (350 kilometers) beneath the cloud tops.
Its magnetic field creates the largest planetary magnetosphere in the solar system.
Sourced image archive
Every image keeps its credit, capture date, description, and original source. Mission imagery links back into the same Andromeda mission catalog.

Associations use destination records plus a curated cross-world manifest for flybys and gravity assists. Mission-name collisions such as Project Mercury and Saturn launch vehicles are deliberately kept with Earth unless they actually visited the planet. Technically obvious; historically necessary.
^^ Childhood favorite planet right here. Still an absolute unit. Still incredible to learn about.
