Cosmology
 

Six planets (and many small planetoids) orbit the central star of this system. Below you'll find an image and a brief description of each.

The Sun

At the center of the system is a G8 star with a radius about nine tenths that of our sun. Its average surface temperature is about 5600°K (5300°C or 9600°F). It's very similar to ours, but you may notice a slight difference in color due to its lesser size. However, seen through a sizable atmosphere, this difference in color would be negligible.

Α (Alpha)

Orbiting at about 36000000m (22000000 miles) is the first planet, code-named Alpha. It's a bit smaller than Mercury and completes a full orbit in about 43 Earth days.
The pocked surface attests it's scant atmosphere—with about a seventh of Earth's mass, it doesn't have enough gravity to hold much of one in place. And without a magnetic field to protect it, any atmospheric gasses that do end up on the surface of Alpha are blown away by solar winds.

Β (Beta)

Beta is the most notable planet in the system. It's just barely smaller than Earth with liquid water and an atmosphere that can (and does) support life. It also has one moon that's fairly similar to ours.
More detailed information on Beta will be added later.

Γ (Gamma)

Hopefully you're seeing a pattern with the names. Gamma is the third planet and has been named with the third letter of the Greek alphabet. At about 330000000m (200000000 miles) from its sun, Gamma completes its orbit in approximately 1175 Earth days. At such a distance from the sun, it's fairly cold and mostly frozen all the time. But tidal forces caused by its two large moons help to break up the ice, producing liquid water, which may support some form of life. At any given time, less than thirty percent of its surface is liquid water, but more lies beneath the ice. It also has a somewhat heavy atmosphere, due to its larger size (more than twelve times the mass of Earth), which holds heat in and causes the planet to gradually grow warmer throughout most of its existence.
This image is shown with no atmosphere to make the icy surface visible.

Δ (Delta)

The largest planet.

Ε (Epsilon)

Another large, gaseous planet.

Ζ (Zeta)

A tiny little ball of dirt and ice, similar to Pluto. It's barely a planet.

There's still a lot more information to be added for these planets, including major moons.
