The name of the moon is Europa.
Europa refers to the smallest of the four moons revolving around Jupiter, and the sixth-largest moon in the Solar System. It is slightly smaller in comparison to Earth's moon. It is mainly composed of silicate rock and bears a water-ice crust and possibly a core of iron and nickel.
It has a fragile atmosphere mainly comprising of oxygen. It exhibits the smoothest surface of any known solid object in the Solar System. The seeming smoothness and youth of the surface have resulted in the hypothesis that a water ocean prevails underneath it that could probably support extraterrestrial life.
