Planet 10. A trans-Neptunian Mars-sized object may be orbiting the sun in the icy reaches of the solar system.

There are an estimated 33,000 objects more than 60 meters across in the belt and three dwarf planets.

Scientists at the University of Arizona’s Lunar and Planetary Laboratory (LPL) were dealing with this issue. They found that KBOs beyond 50 AU from Neptune had their inclination warped.

In January 2016, scientists predicted the existence of a Neptune-size planet. This object was orbiting about 25 times farther from the sun than Pluto is. Astronomers call this hypothetical planet “Planet Nine.” So, if both predictions are correct, one of these putative objects could be the solar system’s 10th planet.

Dr. Kathryn Volk, a postdoctoral fellow at Arizona’s LPL and the lead author of the study explained this. They said, “The most likely explanation for our results is that there is some unseen mass.” She continued “According to our calculations, something as massive as Mars would need to cause the warp that we measured.”

This object could be the tenth planet in our solar system. The planet may have arrived in the outer belt region after a collision with another planet.

Explanation about this.

A star traveling passed our solar system at some point in the past knocked them out of alignment. “That would have required an extremely close passage at about 100 AU, and the warp would be gone within 10 million years, so we don’t consider this a likely scenario,” Renu Malhotra, a professor of planetary sciences at LPL and co-author of the new study said.

The Large Synoptic Survey Telescope will survey the sky, and it should help identify the planet if it exists.

“There are a lot more KBOs out there — we just have not seen them yet,” Malhotra added. “Some of them are too far and dim even for LSST to spot, but because the telescope will cover the sky much more comprehensively than current surveys, it should be able to detect this object, if it’s out there.”

In the future astronomers will need to make more observations.
