That's no moon!
Word has spread around about a new object circling the Sun, and the discussion has begun about whether or not this "Planet Nine" is even a planet at all.
While NASA has said that the 'planet-ness' of Planet Nine is still a theory, many people are already speculating the object's composition, both atmospheric and mineral. However, this has proven difficult due to the object's distance from the Sun and background radiation from the Milky Way.
What we do know about the object, as posted by Science Magazine, is that the object has around the mass of 10 Earths, it has an orbit of 15,000 years, and there's only a 0.007% chance that these observations are just coincidentally the six previously known objects that orbit around Neptune.
As more information surfaces, this is sure to be a thrilling debate and discovery in the astronomical community!
More importantly, how does Pluto feel about all of this?
