Little is known about dark energy, except that it's repulsive. This strange force causes matter to scatter rather than attract. Dark energy makes up 68% of the universe's mass-energy density.

The Heliosphere - made of solar wind, solar transients, and the interplanetary magnetic field, acts as our solar system’s personal shield- protecting the planets by absorbing potentially damaging galactic cosmic rays.

Enaiposha is 3 times bigger and 8 times as massive as Earth. The planet's density means a chunk of it must be lighter than rock but heavier than gas. It is likely that Enaiposha is a water world.
