Urria

About Urria
Urria is a one continent planet about 57.66 million mi2surrounded by water. It is about 4 billion years old. Geographically the planet of Urria is relatively the same as Earth to what we know with the technology we have developed.. We know the ground is made up of mostly soil and that 75% of water is undrinkable.

The Atmosphere of Urria is very similar to Earth too, containing 22% of oxygen and 77% of nitrogen with trace amounts of water vapor, carbon dioxide and another gaseous molecules. Urria's biosphere has significantly altered its atmosphere. Oxygenic photosynthesis evolved 2.7 Gya, forming the primarily nitrogen–oxygen atmosphere.

The highest air temperature ever measured on Urria was 128.1 °F) in Blazing Hills, Elerai, in the Long planes, in 1913. The lowest air temperature ever directly measured on Urria was −112.6°F

The gravity of Urria is the acceleration that is imparted to objects due to the distribution of mass within Urria. Near the Urria's surface, gravitational acceleration is approximately 9.79 m/s2.

Urria orbits the Sun at an average distance of about 155 million km every 365.2565 mean solar days, or one sidereal year. This gives an apparent movement of the Sun eastward with respect to the stars at a rate of about 1°/day, which is one apparent Sun or Moon diameter every 12 hours. Due to this motion, on average it takes 24 hours—a solar day—for Urria to complete a full rotation about its axis so that the Sun returns to the meridian. The orbital speed of Earth averages about 29.79 km/s, which is fast enough to travel a distance equal to Urria's diameter, about 7,925mi, in seven minutes, and the distance to the Moon, 239,053 mi, in about 3.5 hours.

By astronomical convention, the four seasons (Orgath, Lantrií, Drextr, Zontar) can be determined by the solstices—the points in the orbit of maximum axial tilt toward or away from the Sun—and the equinoxes, when the direction of the tilt and the direction to the Sun are perpendicular. In the Northern Hemisphere, winter solstice currently occurs around 21 Perthon; summer solstice is near 21 Cruth, spring equinox is around 20 Braumirt and autumnal equinox is about 22 or 23 Sturmií. In the Southern Hemisphere, the situation is reversed, with the summer and winter solstices exchanged and the spring and autumnal equinox dates swapped.

12 months of the year:

Urrias population reached approximately 31 Million in Lumintan.
