Sânat, the Planet Sedes Draconis

Trade Tongue: http://www.sedesdraconis.com/images/letters/kedan/sanat.gif ("Sânat")

Sânat is a planet only slightly larger than Earth. Its equatorial diameter is about 12,900 km (Earth's is ~12,750).

Sânat rotates once every 23.294 hours.

It orbits its sun, Lêl, at an average distance of 1.14 AU, or 171 million km, with an eccentricity of .063. Sânat completes a revolution around its primary once every 455.0649 Earth (SI) days.

A solar day is the average time from noon to noon; the time for the same spot to come directly under the sun again. A solar day is longer than the rotation period because the planet moves around its sun while it's rotating and so must rotate more than a full circle before it points the same face at the sun again
The extra rotation, by definition, adds to exactly a full circle over the course of a full orbit, there is exactly one more rotation than day in a year.

So Sânat rotates 468.84326 times per orbit, giving it a solar day of 23.344 hours and a mean solar year of 467.84326 local solar days per year (see also Calendar).

Sânat has three satellites.
