PLANET 9 TAKES SHAPE Astrophysicists at the University of Bern have modeled the evolution of the putative planet in the outer solar system. They estimate that the object has a present-day radius equal.
This diagram compares the sizes of the newly-discovered planets around the faint red star with the Galilean moons of Jupiter and the inner Solar System. All the planets found around are of similar size to the Earth. Image credit: ESO/O.
