...I'm going to start putting lots of effort into my planet project: FENTIL.

What is Fentil?
Fentil is a fictional, Earth-sized planet far off in space. It was discovered by accident when a probe was knocked off course by a small asteroid. (the probe was in fact sent into space for this very purpose (to find planets, not to hit into things))

When scientists discovered an Earth-sized planet was much much closer than expected, they were ecstatic. Imagine, then, their surprise when the probe landed to find not only a large ocean of water, but life.
Not just microscopic life or even wriggling fish-worms. Developed life. Life that had conquered land and even the air.

The first convoy of people was sent to the planet a mere 10 years after Fentil's discovery, although due to the distance to the planet, it did not arrive for another 100 years.

So basically, I'm designing an alien planet, including plants and animals.
