Fictional info (?)
Suggested nameRaxtungr Ca
Planet typeHuge cold gas giant
The planet is named after the deity Raxtungr Ca, the spirit of nature.

Its orbital eccentricity is the largest of all known planets in its solar system; at perihelion, Raxtungr Ca's distance from HD 16905 is only about two-thirds (or 96 pct) of its distance at aphelion.

The rotational period and seasonal cycles of Raxtungr Ca are likewise similar to those of Mirmal Delia, as is the tilt that produces the seasons.

It may also have a rocky core of heavier elements, but like the other huge cold gas giants, Raxtungr Ca lacks a well-defined magnetic field.
