Scientists have discovered a possible new planet in our solar system for the first time in 170 years. Evidence of this ninth planet was found on the far edge of the system. It is 10 times bigger than Earth and 20 times farther away than Neptune.

Astronomers at the California Institute of Technology have not directly seen it yet, but there is a strong evidence of its existence, which explains a lot of gravity calculations that did not make sense without it. It’s still a suspicion, but all the calculations strongly point to this possibility.

Derrick Pitts, chief astronomer and director of the Fels Planetarium at the Franklin Institute in Philadelphia, joins “CBS This Morning” to discuss the math and evidence behind the planet.

Now the rest of the astronomical community is to decide whether this info is viable and observe the sky to actually see it.
