Its orbital period around HD 164922 of 1200 earth days is the longest of all the planets in its solar system.

It is named after the deity Calpersie'daph, the creator of the sky.

Calpersie'daph is a cold planet and is sometimes called Earth's "twin planet" because of their similar size, mass, proximity to HD 164922, and bulk composition.

The largest moon, Polycor-noe, has a diameter greater than that of the planet Mercury.
