Researchers put the 'highest probability' of Planet Nine's location near aphelion - around 60 degrees in Right Ascension, 'pretty close to the galactic plane'

If it were at the median distance of aphelion, Planet Nine would be roughly 46.5 billion miles away from the sun

They used the clustering of the Kuiper Belt Objects and found there is only 0.4% chance the clustering is a weird occurrence

They estimate Planet Nine has a mass of 6.2 times that of the Earth and is closest to the sun at 300 AU
