La Uni\u00f3n Astron\u00f3mica Internacional cambi\u00f3 la categor\u00eda de Plut\u00f3n a planeta enano. \u00a1Despu\u00e9s de 76 a\u00f1os de ser descubierto!
Determin\u00f3 que las nuevas condiciones para ser un planeta son:
– Orbitar alrededor del Sol
– Tener una masa grande con gravedad suficiente para hacerlo redondo
– Ser el \u00fanico cuerpo en la misma \u00f3rbita
Y debido a que comparte \u00f3rbita con otros cuerpos, ahora tiene otra categor\u00eda.
\u00a1CONOCE A PLUT\u00d3N!
Plut\u00f3n forma parte del Cintur\u00f3n de Kuiper: una regi\u00f3n en forma de rosquilla situada m\u00e1s all\u00e1 de la \u00f3rbita de Neptuno repleta de miles de peque\u00f1os cuerpos helados.
Una vuelta al Sol toma cerca de 248 a\u00f1os terrestres.
Plut\u00f3n es un peque\u00f1o cuerpo rocoso similar a la Tierra.
Su \u00f3rbita es pronunciadamente el\u00edptica, el Sol no est\u00e1 en el centro y su trayecto est\u00e1 muy inclinado respecto a los planetas.
