That’s where Planet Nine would move most slowly and, therefore, spend most of its time. Search in the red area, these astronomers suggest! Image via Mike Brown.
So where is it?
William Herschel discovered Uranus in 1781. Johann Gottried Galle (and others) discovered Neptune in 1846. Clyde Tombaugh discovered Pluto in 1930. Whose name will fill in the blank for the discovery of Planet Nine? Will it be you? Your search just got easier, as last week two scientists provided a map (above) showing the probable orbit of Planet Nine, and its probable location within that orbit.
Mike Brown and Konstantin Batygin, both of Caltech, announced in early 2016 ...
