Mercury Makes Waves Cruising through the Solar Wind

Mercury orbits the Sun in a unique regime. The solar wind is still fresh from the Sun, and the Sun’s magnetic field strength is rapidly waning. Furthermore, Mercury’s highly elliptical orbit means the planet passes through a wider range of distances from the Sun than any other planet. As a result, Mercury provides a unique opportunity to study how the Sun’s influence on a planet varies with distance.
