Deep Dive on Jupiter's Moon Europa Infographic
Jupiter’s icy moon Europa may be the most promising place in the solar system to find present-day environments suitable for life beyond Earth.
Discovered: Jan. 7, 1610 by Galileo Galilei
Explored by: Pinoeer 10, Pioneer 11, Voyager 1, Voyager 2, Gallileo and Hubble spacecraft
Classification: Ocean Moon
Distance from the Sun: 5.2 Astronomical Units (Earth = 1 Astronomical Unit)
Orbital Period at Jupiter: 85 hours (3.6 Earth Days)
Atmosphere: Europa has an extremely thin oxygen atmosphere, too thin for humans to breathe.
Ocean Depth: ~ 60 miles (~ 100 kilometers) Scientist believe that Europa has twice the size of Earth’s oceans combined.
On the Surface: Europa's surface ( surface thickness estimates range from 2 to 20 miles (3 to 30 kilometers), is covered with a vast network of linear features such as cracks, ridges, and bands, as well as other smaller circular features that include pits, spots and domes.
Ingredients for Life? Abundant liquid water, energy and the right chemical elements make Europa one of the best places in the solar system to seek present day life beyond Earth.
