A Look at Neptune's Magnetosphere
The magnetosphere of Neptune is a lot like that of Uranus, medium sized but still much larger than the Earth's. It is large enough to hold all the moons.
Like Uranus, is probably made in the middle and with ice, rather than with iron at the center.
Like Uranus, the magnetosphere of Neptune has an extreme tilt, almost 60 degrees. Because Neptune itself is not tilted however, the magnetosphere of Neptune has more normal parts.
Like Saturn, Neptune's magnetosphere produces aurora but very faint ones, as well as radio signals such as whistler waves, chorus and hiss.
