Object guide
Europa has a smooth icy shell that likely hides a global subsurface ocean. Its surface shows a network of cracks and ridges; the ocean beneath makes Europa a prime target in the search for life. Europa is approximately 3,121.6 km across.
How to observe Europa
Europa is resolved as a separate world mainly through imaging or spacecraft data; visually, its relationship to jupiter is the key observing context.
