Did you know that #Mercury has some of the oldest surfaces in the solar system?
Some of its craters and features have been around for about 4 billion years, making it one of the most ancient-looking places in space.
Because Mercury doesn’t have an atmosphere to erase or change its surface, those ancient features have been preserved almost untouched.
