Little Planet, as its name hints, is a tiny,[2] spherical astronomical body with characteristics similar to those from earth. As such, it possesses a breathable atmosphere and its own flora and fauna, which are very like those from Sonic's world. Described as a beautiful world[2] and a center of peace,[5] its surface is mostly covered by large landmasses that make it mainly green in color. There are also various bodies of water that are given a blue color when seen from space. Presumably due to its small size, the various forests and mountains on Little Planet can be seen from far away. Additionally, the planet possesses its own gravitational field. However, much of Little Planet remains surrounded in mystery.[2]
Unlike earth, Little Planet has many mystical properties; most noticeably, it is able to appear out of nowhere on Never Lake for one month every year,[4] though it is unknown where it can be found for the rest of the year. Additionally, it is able to freely fly around, and is unaffected by the gravitational pull of Sonic's world when it makes its visit on that planet. Described as "a world that defies time" and "where past, present and future collide",[2] Little Planet is known for hosting the Time Stones, mystic relics that allow their user to travel through time and re-write history to cause miracles to happen.[4][5] There are also Time Warp signs around the planet, which are used to enter the Time Warp and travel between different time frames: the present, the past, and a fluctuating future, by moving at the speed of light.[6] Also, it is possible that Little Planet might have a will of its own; after Sonic saved Little Planet at the end of its incident, the planet left Sonic's world while displaying sparkles that formed Sonic's face
