On the Sun-facing side of Earth, the magnetopause is located at a distance of approximately 10 Earth radii, which is almost 65,000 km (40,000 miles) from the planet.12

At this location, the pressure of Earth's magnetic field reaches an equilibrium with the opposing pressure of the solar wind. This region, which has a characteristic thickness of about 100 km (60 miles), serves as the outer boundary of the magnetosphere.12
