Нашли новую планету за Нептуном, большую:

...We find that the observed orbital alignment can be maintained by a distant eccentric planet with
mass ~10 m⊕ whose orbit lies in approximately the same plane as those of the distant KBOs, but whose perihelion
is 180° away from the perihelia of the minor bodies. In addition to accounting for the observed orbital alignment,
the existence of such a planet naturally explains the presence of high-perihelion Sedna-like objects, as well as the
known collection of high semimajor axis objects with inclinations between 60° and 150° whose origin was
previously unclear...

Пока только evidens... Но интересно. Планета значительно более чем в10 раз тяжелее Земли и в 20 раз дальше Нептуна

our calculations suggest that a perturber on an a′∼700 AU, e′∼0.6 orbit would have to be somewhat more massive (e.g., a factor of a few) than m′=10 m⊕ to produce the desired effect.
