Resumen de Planet hunting with the big bang
The fate of an entire world is at stake. Astronomers are enlisting every telescope and space probe they can think of in the hunt for the solar system's potential ninth planet, and some unlikely sources may be key to tracking it down. In January, Konstantin Batygin and Mike Brown at the California Institute of Technology in Pasadena announced they had found indirect evidence for "Planet Nine". Following up on previous hints, they analyzed the wonky orbits of small bodies beyond Neptune and determined they may have been caused by a planet 10 times the mass of Earth, with an orbital axis 700 times longer than the distance from Earth to the sun.
