Planet X? nd I thought Pluto was considered a planet again

Did they reinstate Pluto? Well that would be good news. But Planet X is the supposed tenth planet in our solar system. An image captured a while ago by some satellite we sent to take pictures of Pluto caught glimpse of a large circular shadow behind it. And then I heard from somewhere about the sun having an uneven rotation that was not coinciding with there only being nine planets. Something about how the planets revolving around the Sun cause it to wobble in comparison to the location of the planets, and that the Sun wobbles in such a way that indicates there is something of great mass in orbit around the Sun we can't see. I can't find any good youtube videos that show this that are less than an hour long though :(

I quickly looked up the Pluto thing, apparently they are co spidering it. I think the correct term is dwarf planet As for planet X, wouldn't we have seen it by now, we've seen so many planets and galaxies far beyond ours, wouldn't we see something so relatively close. Also that mass could be from the kuiper belt and the massive asteroid belt between mars and jupiter. It would be cool if another planet that close was discovered though
