This Is Why Scientists Think Planet Nine Doesn’t Exist

“Of course, this study isn’t enough to rule out Planet Nine; it still could be out there. As a counterpoint, Mike Brown has contended that a different survey strategy could have been definitive, and OSSOS simply isn’t a good survey for indicating yea or nay on Planet Nine. But remember, the old saying goes, “where there’s smoke, there’s fire,” indicating that if you observe an effect, it likely has a cause.

If you all of a sudden discover that what you thought was smoke was a figment of your imagination, it doesn’t mean there wasn’t a fire, but it sure does make the hypothesis that there ever was a fire a lot less compelling. The OSSOS study doesn’t rule out Planet Nine, but it does cast doubt on the idea that the Solar System needs one. Unless a deeper, better survey indicates otherwise, or Planet Nine serendipitously turns up, the default position should be its non-existence.”

Is there another massive planet in the Solar System? Do we have a super-Earth after all, between the masses and sizes of Earth and Neptune? And has it only gone undiscovered until now owing to our telescopic limitations, and the fact that it’s so much more distant than the presently known planets?

It’s possible. That’s the radical idea behind Planet Nine, proposed nearly three years ago by Konstantin Batygin and Mike Brown. They looked at the unusual orbits of a number of Kuiper Belt objects, and conjectures that a ninth planet, located hundreds of times as distant as Earth is from the Sun, could be the culprit. But on closer inspection, the evidence that they’re looking at might just be biased, and there may be no Planet Nine at all.

There may not even be a puzzle to solve. Come get the scientific story on Planet Nine that you haven’t heard today.

The Scientific Truth About Planet Nine, So Far

“The most surprising results from the Kepler mission was that the overwhelming majority of planets in the Universe were not small, rocky worlds like Earth or Mars, nor large, gas giant worlds like Neptune or Jupiter, but rather in-between worlds, collectively classified as Super-Earths. Ever since that discovery, astronomers have wondered why there simply aren’t any of those worlds in our Solar System. If the Planet Nine hypothesis is right, then there actually is one, and this is the best season for finding it!”

In January of last year, astronomers Konstantin Batygin and Mike Brown shocked the world by proposing that there was a world larger than Earth located some five-to-ten times as distant as Neptune. That this world — known as Planet Nine — was causing the ultra-distant Kuiper belt objects we’d discovered so far to all have predicable, peculiar properties. And the observations matched up really well. But in science, post-dictions aren’t enough. You need to make new predictions for objects you can then go out and measure, and see how they line up. In the case of Planet Nine, there are four pieces of indirect evidence that can be measured, and one piece of direct evidence that will settle the issue once and for all: actually locating Planet Nine.

The indirect evidence looks good, and we’re fast approaching the best season for hunting Planet Nine. Come get the status update today!
