Pol/Data

Pol是Jool五颗天然卫星中最小的一个。这里的地形（相对）非常崎岖不平，分布着大型的山脉，让它看起来像是一颗谷类的花粉。

Pol的重力很低，在Kerbol 星系中排名倒数第二，只比Eve的卫星Gilly稍大些。因此在这里，双组元液体燃料火箭发动机绝对是牛刀杀鸡 —— 利用RCS发动机就可以完成着陆。由于这里崎岖的地形，到处遍布着高山、峡谷等等，45度的大斜坡，锯齿状的岩石，以及它非常小的引力范围，新手的着陆还是有一定难度。

Orbit

Pol is in a large orbit around Jool with moderate eccentricity and inclination, which indicates it may be a captured asteroid, like Gilly and Bop. Pol is tidally locked to Jool.

Topography

Pol's uneven surface with Jool and Laythe in the backround.

Pol has many unique characteristics. The surface is wrinkled and uneven. It has many spiked mountains and very large cliffs that can reach up to 4km high, and many kilometers wide. Many mountain ranges are circular, and form bowl-shaped valleys. Its surface color ranges from brown over pale yellow to pale green. It appears to be composed of various phosphoric or sulfuric compounds and is covered in peculiar spire-shaped rocks.

But the surface of Pol is still not as irregular as that of Bop, despite lower gravity. This suggests volcanic activity that re-paved the surface, or that Pol was formed via low-velocity accretion at relatively low temperatures.

A rover is hard to drive on the surface of Pol because of the uneven terrain and low gravity

An orbit under 3000 meters is unwise, as it will almost always result in colliding with a mountain, spire, or plateau.

Trivia

• Pol's name is likely derived from its uncanny resemblance to a grain of pollen.
• Pol's name may or may not have anything to do with the T.V. show The Incredible Dr. Pol on the National Geographic channel.
