Suggested nameHyrteadra
Planet typeHot planet
Hyrteadra is the fourth planet from 2MASS J20052510+4431298 and the second-smallest planet in its solar system. It is the second-brightest natural object in the night sky after Side, reaching an apparent magnitude of -5 - bright enough to cast shadows at night and, sometimes, visible to the naked eye in broad daylight.

It is a hot planet planet with a mass one-thousandth that of 2MASS J20052510+4431298, but two-and-a-half times that of all the other planets in its solar system combined. It is named after the deity Hyrteadra, the goddess of dreams.

Its orbital eccentricity is the largest of all known planets in its solar system; at perihelion, Hyrteadra's distance from 2MASS J20052510+4431298 is only about two-thirds (or 40 pct) of its distance at aphelion.

Its north and south poles, therefore, lie where most other planets have their equators.
