Planet X: finding the Solar System’s invisible tenant

No Comments

The possible existence of an unknown planet in the limits of the solar system was announced in January. This announcement was based on theoretic calculations of the effect of a possible planet on the orbits of a series of smaller celestial bodies. This hypothetical planet is hard to find and hasn’t been observed yet, but it poses a series of interesting questions: What is this hypothetical planet like? What is the scientific basis for this announcement? Planet X represents the unknown in the Solar System, which continues to amaze us.

Physicist Ricardo Hueso, member of the Planet Sciences group of the UPV/EHU, shall host a talk under the title ‘Planeta X, en busca del inquilino invisible del sistema solar’ (‘Planet X: finding the Solar System’s invisible tenant’) March 16th at Azkuna Zentroa.
