Europa: Facts - NASA Science
Europa’s surface is made of water ice and so it reflects 5.5 times the sunlight than our Moon does. Europa orbits Jupiter at about 417,000 miles (671,000 kilometers) from the planet, which itself orbits the Sun at a distance of roughly 500 million miles (780 million kilometers), or 5.2 astronomical units (AU).
Ingredients for Life | Why Europa – NASA's Europa Clipper
NASA is sending the Europa Clipper spacecraft to conduct a detailed exploration of Europa and investigate whether the icy moon, with its subsurface ocean, has the capability to support life. Understanding Europa’s habitability will help scientists better understand the potential for finding life beyond our planet and guide us in our search.
