One of the greatest things about our solar system is that every single planet is unique. From Saturn’s magnificent rings to sulfuric acid of Venus’s atmosphere to Earth’s ability to sustain life. In addition, some planets offer fascinating magnetism. Our own magnetic field keeps us safe from harmful radiation and creates stunning aurorae. Jupiter’s magnetic field is the largest single object in the entire solar system! One planet seems to outdo all the others in terms of its uniqueness—Uranus. There’s plenty separating Uranus from its fellow orbiters. For instance, it’s the only planet to use the Greek deity name instead of the Roman (Caelus). On an astrophysical level, Uranus is equally as puzzling. Uranus rotates on a whopping 98-degree tilt! Basically, it’s north and south poles are where Earth’s equator would be. It’s thought this unusual axis was caused by a massive collision, which might also explain it’s rings. However, perhaps the strangest thing about Uranus is its erratic magnetosphere. A magnetosphere is basically the magnetism surrounding a planet much like an atmosphere does. Unlike Earth’s and Jupiter’s which are pretty much constant, the magnetic field on Uranus turns off and on as if someone is flipping a switch. But what causes this strange magnetic behavior? An Off-Kilter Planet As mentioned earlier, Uranus orbits the sun on a perpendicular angle, leaving half the planet exposed to the sun for almost 48 years at a time. As a result, Uranian magnetosphere is not equally grounded between its north and south pole. In fact, the magnetic field sits at a 60-degree angle. This essentially results in a sort-of somersault effect. The magnetosphere tumbles end-over-end which in turn leads to unstable, spotty forcefield. So what makes the magnetosphere turn off and on? Enter the Sun Because Uranus’ magnetosphere is out there in space doing front flips like it’s a circus clown, it deals with solar wind as it comes. Back here on Earth, where our magnetic field is a bit calmer there is pretty consistent protection from deadly radiation and solar flares. However, sometimes Earth’s magnetism meets directly with solar wind and the process of magnetic reconnection occurs, resulting in an aurora. However, because the magnetism around Uranus won’t stay put, it comes into contact with solar flares much more consistently, leading to a burst of magnetic energy. Imagine someone flicking a light switch to create a strobe effect. What ramifications does Uranus’ crazy magnetosphere have on the rest of the solar system? Well, none actually. This issue is strictly its own. However, there is one benefits to studying other planets’ magnetism. We are learning that every planet is unique and that the universe abounds with diversity.
