Tobano is a large planet tidally locked around Gwa, a type M2V red dwarf star in the Deras grid of the Andromeda Galaxy. Tobano is the originating planet of the Khoikapek species, which has come to spread throughout much of the cluster.


Tobano orbits Gwa at a distance of 17,892,580 kilometres; at this distance, Gwa has an apparent diameter of 118.8'. Tobano takes just 37 days to orbit Gwa; the planet's day length is also 37 days, due to the fact that it is tidally locked. The axis of Tobano is exactly perpendicular to the ecliptic and the planet has developed a very stable orbit due to strong tidal forces caused by a close proximity to its star.

Due to the fact that the planet is tidally locked, from the surface the sun appears to be fixed in the same point in the sky. The subsolar point is the point directly beneath the sun (from which the sun can be seen to be directly overhead). The antisolar point is the point directly opposite the subsolar point (from which it would take the furthest to travel to a part of the planet illuminated by sunlight). The terminator is the line along which there is a constant sunset; it separates the subsolar and antisolar hemisphere.


Tobano has a diameter of 61,484 kilometres, though this varies significantly depending on which point the diameter is measure between; tidal forces have caused the planet to bulge out at the subsolar and antisolar points. Due to its large size, Tobano's molten core is still very hot and active, leading to large amounts of geological activity, which can lead to unexpected climate fluctuations caused by, for example, supervolcano eruptions.

Tobano's high gravity means that most of the landscape is heavily eroded, leading to relatively shallow oceans and flat landmasses; almost all of the land area of Tobano is in the form of a huge, very rougly circular supercontinent (Poka) centred around the subsolar point. Geologists are not exactly sure why this is, but it is likely not by chance. The supercontinent of Poka is made up of a number of huge cratons, which, through the planet's history, seem to have 'jostled' around the subsolar point, ever remaining a single supercontinent. Poka covers about 80% of the subsolar hemisphere.
