Trivia

 * This planet was created at some point during my tenure as a High School student, and was therefore created sometime between 1999 and 2001.
 * The planet was originally named "Yuirnasaria", but in the process of its rediscovery, I decided to respell its name to make it look better.
 * Geothermal activity on Yhurnasaria is called "yhurothermal", as geothermal strictly refers to the Earth.
