what is the space shuttle used for
Europa I think.
Europa, one of Jupiter's moons, is a natural satellite where it is believed that ice flows. This is due to its icy surface, which shows evidence of crustal plates moving and shifting over time, suggesting the presence of subsurface oceans kept warm by tidal forces.
An icy satellite of Jupiter is a moon that is composed predominantly of ice and rock. Examples include Europa, Ganymede, and Callisto. These moons have subsurface oceans beneath their icy shells and are thought to potentially harbor conditions that could support life.
It is a natural satellite.
Jupiter has 53 named satellites - the biggest is Europa.
The moon, and moons of the other planets (Titan, Europa, Ganymede, Phobos etc). But the planets themselves, even Earth is natural satellites to the Sun.
The Moon is the natural satellite of the Earth. The Moon does not have satellites.
