Terra (mythology) In ancient Roman religion and myth, Tellus Mater or Terra Mater ("Mother Earth") is a goddess of the earth. Although Tellus and Terra are hardly distinguishable during the Imperial era, "Tellus" was the name of the original earth goddess in the religious practices of
Planet Nine X, Planet Next, or Giant Planet Five." 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.
