Planet Nine Planet Nine Planet Nine is a hypothetical planet in the outer region of the Solar System. Its gravity could explain the unlikely clustering of orbits for a group of extreme trans-Neptunian objects (eTNOs) that orbit beyond Neptune with average distances greater than 250 AU. These eTNOs tend to have their points of closest approach to the Sun clustered in one direction, and many of their orbits have a similar tilt. This evidence suggests that the gravity from a large undiscovered object is influencing the orbits of the most distant known Solar System objects. This undiscovered super-Earth-sized planet would have an
Battle for Terra won the Grand Prize for Best Animated Feature at the 2008 Ottawa International Animation Festival. Mala (Evan Rachel Wood) and her friend Senn (Justin Long) are young alien creatures who live on Terra, a planet from a star system in the Milky Way. Terra is a peaceful planet of alien creatures who have a rich semi-advanced culture. One day a large, mysterious object blocks the Terrian sun, piquing the Terrians' interest. However, since the Terrian culture bans the development of new technologies, such as telescopes, without the approval of the ruling council, none of the inhabitants are able to get
