It’s been years since Pluto got the axe as the ninth plane in our solar system, but it’s possible that there’s a replacement out there, according to new research. This new planet would be far larger than the dwarf planet of Pluto, and it would even dwarf Earth based on gravitational calculations.

NASA recently issued a statement noting that a ninth planet may be the best explanation for strange gravitational anomalies in the solar system. Some objects far out in the solar system are behaving strangely, and some orbital planes of several planets seem to be altered from where the should be, indicating a massive object circling the sun at an orbit way farther out than even Pluto.

Some calculations suggest that Planet Nine would be 10 times the size of Earth, and 20 times as far from the sun as Neptune, which indicates just how truly massive our solar system is and just how far out the sun exerts influence. Such a discovery would certainly be a huge finding for astronomers.

“It might be lingering bashfully on the icy outer edges of our solar system, hiding in the dark, but subtly pulling strings behind the scenes: stretching out the orbits of distant bodies, perhaps even tilting the entire solar system to one side,” the NASA statement reads. “If a planet is there, it’s extremely distant and will stay that way (with no chance — in case you’re wondering — of ever colliding with Earth, or bringing “days of darkness”).It is a possible “Planet Nine” — a world perhaps 10 times the mass of Earth and 20 times farther from the sun than Neptune. The signs so far are indirect, mainly its gravitational footprints, but that adds up to a compelling case nonetheless.”
