Question

How distant is Jupiter moon Europa from the sun?

Answer 1

Hint: Europa's surface is blasted by radiation from Jupiter. That's a nasty thing for all times on the surface – it couldn't survive. But the radiation may create fuel for all times in an ocean below the surface. The radiation splits apart water molecules (H2O, made from oxygen and hydrogen) in Europa's extremely tenuous atmosphere.

Complete answer:
Europa the moon orbits Jupiter, the fifth planet from the Sun. Jupiter orbits the Sun at a distance of about 484 million miles (778 million kilometers). On the average, Europa's distance from the sun is about 485 million miles (or 780 million kilometers).
Distance from Jupiter: Europa is Jupiter's sixth satellite. Its orbital distance from Jupiter is 414,000 miles (670,900 km). It takes Europa three and a half Earth-days to orbit Jupiter.
Europa is tidally locked therefore the same side faces Jupiter in the least times. Europa is 1,900 miles (3,100 km) in diameter, making it smaller than Earth's moon, but larger than Pluto. It's the littlest of the Galilean moons.
After the last of its gravity assists by an inner planet, a Europa-bound spacecraft would still take about three years to succeed in Jupiter, even as a smaller spacecraft would be on an immediate route from Earth.

Note:
Europa receives 5.4 SV of radiation per day, which is approximately 1,800 times the typical annual (yearly) dose of a person's on earth stumped level. Consequently, a person would require significant radiation shielding to survive at or near the surface of Europa.
