Io

Io is one of the 4 Galilean moons of the planet Jupiter. It is the hottest moon in the solar system, recording up to 2,600F around its 400 volcanoes, hotter than Earth's volcanoes. Due to its proximity to Jupiter, it receives 3,600 rem a day (compared to 0.001 rem per day on Earth). This is 1,000 times stronger than needed to kill a human being.
