The sun is tilted by six degrees with respect to the plane of the planets. The reason for the non-zero solar obliquity has been a mystery since it was first discovered by Sir Richard Carrington in the mid-1800s. It turns out that planet nine can actually tilt the sun. The fact that the sun is tilted, even if it's only by six degrees, the fact that the sun is tilted, you know, the sun is the most massive thing in our solar system by a huge margin. And it's oriented differently than everything else in the solar system. That is an incredibly strange phenomenon for which there really has not been that many explanations even attempted over the last hundred and fifty years. It's naturally explained by planet nine being exactly where we think planet nine is, which it's one of these mysteries that we think is now solved. It's been such a mystery that people haven't even really talked about it very much over the last hundred and fifty years because it's just been so difficult to think of what it is. It has been known since the mid-1800s that the sun is tilted over the years. People have put forth various explanations for it. One possibility is that the sun was interacting with the protoplanetary disk via magnetic fields. It's also possible that the disk was just asymmetrical from the beginning. And it's also possible that the sun actually had a stellar companion a long time ago. It was a moment of inspiration. Not all projects start out this way. Not all results really come. Some of them come, you know, slowly dons on you. We were sitting in Constantine's office one afternoon and we were actually thinking about a different problem entirely, which is how planet nine would interact with these very distant objects in the Kuiper belt that made us originally think that planet nine was there. And in just a moment as we're thinking about it and we're doing this with our hands, trying to think of directions, things are going, I think we both realize it about the same time. It's like, oh, it's going to make the sun look tilted too. And it was very clear from the way we did our fingers that it was going to make an effect. What we didn't know until we did the calculations was how much of an effect was it going to have and what direction was it going to go. But we knew it had to do something. planet nine has been scattered out into the distant solar system. So because it has an orbital period that's so long, it has an enormous amount of angular momentum, right? As much almost as the rest of the solar system combined. So even though as an object, it is not as massive as Jupiter. It has a huge lever bar. And using that lever bar, it can effectively torque the rest of the disk of the solar system by six degrees over the age of the sun. Next always next on our list is find the planet. We think we have it narrowed down to a pretty small patch in the sky that we have to look at. Small patch in the sky still means we need many, many nights on the telescope. We are pretty convinced that by maybe next, the end of next winter, we will have been able to cover enough sky that we will actually be able to find it. When we find it, we both show that this hypothesis has been correct. We learn about it. But we also see how much of the sun, how it should have tilted the sun to and see if this is the only thing that's been tilted the sun or if other things are around
