Planet Nine?? (No, It’s NOT Pluto This Time)

Many get excited by the search for planets, as astronomy magazines name off new exoplanets every other month. But what many may not know is that scientist have brough their search for planets back home to our own solar system, searching for what may truly be our special “Planet Nine” (Sorry, Pluto still doesn’t make the cut).

As of 2 days ago, 139 planets, or what have been labeled as “minor planets,” have been found beyond the orbit of Neptune and even far beyond the orbits of Pluto (ranging 30 to 90 AU from the Sun). As of now, these TNOs simply remain unpublished as astronomical objects that orbit the sun, but as Scientist continue to survey them, they seem to get closer and closer to finding one that can truly be labeled as a planet. Using the Dark Energy Camera in a Chilean observatory, Scientist have been able to follow and catalogue the path of multitudes of TNOs to find out if they are the “real deal.”

Scientist have hypothesized that they must come across a ninth planet sooner or later due to certain astronomical phenomena that are explained by little else. One source of evidence for this planet are 6 objects in the Kuiper Belt with elliptical orbits tilted with respect to the solar plane. Furthermore, the 6-degree tilt of our actual planets to the solar planet could be described by a sixth planet. Finally, there are some objects in the Kuiper belt that orbit in the opposite direction as most others. All of these facts, scientist believe, point to the existence of another, possibly giant, planet in the great outer depths of our solar system.

One thought on “Planet Nine?? (No, It’s NOT Pluto This Time)

  1. It would be so interesting to find a ninth planet in our solar system! However, they will not likely be as gravitationally bound as the eight planets we currently have in our system. And the most intuitive reason we might have been able to find the ninth planet is due to its period, which is probably so much longer than Neptune so we aren’t able to detect it as easily. I always find exciting when they do find a planet that could be considered the ninth one in our solar system bc they start wondering if it fits their general definition of a planet and then people start arguing about how we should define planets as.
