My current event was about “if” there is a 9th planet in our solar system. Scientists from the California Institute of Technology were looking at orbits of things in the Kuiper Belt. (That’s a line of asteroids, dwarf planets and icy bodies, past Neptune). The first body that caught their attention was Senda, a dwarf planet. Then scientists looked at other orbits in the area, and they saw that things were all on one side of the sun. They figured there must be a bigger planet on the other side, one that was not orbiting in a strange pattern. In fact, they thought because it had a more normal orbit, it was actually making the dwarf planets orbit strangely because of its gravitational pull.
If this ninth planet exists, it might be three times the size of earth, and it could weigh between 1-10 times the weight of earth. But no one knows for sure. Scientists also don’t know what it looks like or what it’s made of — the planet is so far away from the sun.
This possible planet was unknown before, because it is so far away from us. We don’t know if it even exists. Remember, I said IF there was a 9th planet? The evidence that it exists is that the scientists can measure the orbits with a computer program. If there wasn’t a 9th planet, the weird orbits wouldn’t happen they way they found. One of the scientists from CalTech, Mike Brown, is the guy who made Pluto into a dwarf planet.
I think the 9th planet is real. I think they should name it after a Greek or Roman god. Earth is the only planet in our solar system that wasn’t named after a Greek or Roman god.
This is interstellar news.
