Mercury is a strange, hot mess of a planet. This rock is closest to the Sun, but its surface temperatures can plummet to as low as 180 °C (290 °F). It has the strangest sunrises and sunsets in the entire Solar System. And one day on this planet lasts about two years. But you don't have to survive a whole day down there. We're sending our team member Chase on a mission to spend just 5 seconds on Mercury.
