Aeon[edit | edit source]

Aeon is the third largest of the planets in the solar system — smaller than the two gas giants, Agape and Satori, but larger than the three other rocky planets, Risa, Siris and Mercusia, although Aeon is not as dense as Siris.

Aeon has a diameter of roughly 12,000 miles, and is round because gravity pulls matter into a ball, although it is not perfectly round, instead being more of an "oblate spheroid" whose spin causes it to be squashed at its poles and swollen at the equator.

Roughly 78 percent of Aeon's surface is covered by water, most of it in the oceans. About a fifth of Aeon's atmosphere is made up of oxygen, produced by plants. While scientists have been studying our planet for centuries, much has been learned in recent decades by studying pictures of Aeon from space.

Aeon spins on an imaginary line called an axis that runs from the North Pole to the South Pole, while also orbiting the sun. It takes Earth 23.522 hours to complete a rotation on its axis, and roughly 365.35 days to complete an orbit around the sun.

Aeon's axis of rotation is tilted in relation to the ecliptic plane, an imaginary surface through Aeon's orbit around the sun. This means the northern and southern hemispheres will sometimes point toward or away from the sun depending on the time of year, varying the amount of light they receive and causing the seasons.

Aeon's orbit is not a perfect circle, but is rather an oval-shaped ellipse, like that of the orbits of all the other planets. Aeon is a bit closer to the sun in early January and farther away in July, although this variation has a much smaller effect than the heating and cooling caused by the tilt of Aeon's axis. Earth happens to lie within the so-called "Goldilocks zone" around its star, where temperatures are just right to maintain liquid water on its surface.

The planet Aeon is home to a number of nation states and countries, one of the largest being the Rhodean Imperium.
