Jupiter

Jupiter is the fifth planet from the Sun and the largest in the Solar System. It is a gas giant with a mass more than two and a half times that of all the other planets in the Solar System combined. It has four significant moons called Galilean moons and tens of other smaller moons.

If you want to swim, you can try the moon Europa. There are however several problems: Europa is not yet part of the European Union (so you need a passport), surface temperature is around -160 ℃ (so a lot colder than in a freezer) and the ocean is covered by several tens kilometers of ice.

As of Monday, February 2nd 2024, Jupiter is in Bratislava on Jelačičova street.
