Hot Jupiter Regime and Solar System (IMAGE) Arizona State University Caption Hot Jupiters (red dots) are large planets similar to our Jupiter, but orbiting close to their stars. Four hot Jupiters have magnetic field strengths much greater than that of Earth, Saturn, Uranus, or Neptune -- or even Jupiter itself. The left scale shows field strength in gauss, the bottom scale shows orbital distance from the star in astronomical units; Earth orbits the Sun at 1 AU.
