Question

Quizplus · Accepted Answer

The moons of Neptune, particularly Triton, have extremely low temperatures of around -235°C (-391°F) due to their distance from the sun and the thin atmosphere. This makes them the coldest place in the solar system that a tourist could potentially visit. The other options may have cold temperatures, but not as extreme as the moons of Neptune.
