Gagarin

Gagarin is a world orbiting the star Delta Pavonis.

Characteristics
Gagarin weighs in at 3.04 Earths, and orbits slightly more distant from its sun than the Earth. It has a thick atmosphere rich in oxygen and an extremely diverse biosphere.

Gagarin is a dying world, undergoing its last "explosion" of life before its aging sun begins to expand and boil off the planet's oceans. The atmosphere is almost 80% oxygen because of the density of plant life on the world, and the atmopshere is thick with a bluish haze. The world's five continents are mostly low-relief and covered in dense rainforests, where life has diversified to fill any niche imaginable.
