(Pronounced: Zare Gwarkata Prime)
A volcanic planet in same orbit path as another planet, hits the other's moon each 22 years. Populated by lizards similar to (Hork-Bajir on Animrophs, google, you wuss) and once the moon is about to hit, the lizards jump into holes in the ground and bury themselves. The orbits are so close before they hit, the animals on each planet can fly to the other planet.
