Jupiter has 62 known satellites. The most well known are
the four galilean moons: Europa (3138Km in diameter), Callisto (4800Km), Ganymede (5262Km), and Io (3630Km).
Information:
Jupiter's atmospheric components consist of: 90% Hydrogin, 10%
Helium, and .07 Methane.
A year on Jupiter is 11.86 in Earth days.
Average distance from the sun: 484,000,000 Miles

Below is a picture of Jupiter's smallest moon, Europa. The icy moon is riddled with pinkish
scars across its surface and are contaminated with sulphurous chemicals. Europa's icy crust floats on top of a subsurface
ocean, kept liquid by tidal heat. When jupiter's gravity tears the surface, it allows water to well up from below and
it eventually freezes, healing the gap.
Ganymede, the largest satellite in the solar system.
Ganymede has long strips of parallel ridges called sulci, they show where Ganymede's surface has
pulled apart, causing strips of terrain to slip over do they now overlap each other, similar to a line of toppled dominoes.

galilean moons.
