What it's like to stand here

Standing on Charon, you would weigh about 97% less than you do on Earth. Its yellow dwarf, like our Sun sun looks 0.03× as wide than ours, bathing the surface in warm white light. A year passes in just 248 years, and at an estimated -220°C (-364°F) it is colder than almost anywhere in the solar system.
