## Koratos's information

This planet is a cool superterra that has been observed to have multicellular life (marine, terrestrial). The planet was discovered on April 19th, 2010. The planet is distinct for its brown dominated appearance with the lack of significant green vegetation. The planet has a diameter of 12,999.38 miles or 1.640 R⨁, with the mass of the planet being 3.8603\*10^25 kilograms, or 6.4616 M⨁.  The density of the superearth is 8.1581 grams per cubic centimeter, with the oblateness being very low, with it being 0.0129922. The effective temperature on this tundra of a world is 244.58 kelvin, with the average temperature of the planet being 247.93 kelvin. The conversions for that are t -13.396 degrees fahrenheit, or -25.22 degrees celsius. The earth similarity of the planet is a very low amount with it being just 0.767, which is not high enough for humans to colonize without some terraforming. The rotational period of the planet is almost precisely 10 hours, but instead it is 10 hours, 0 minutes, and 55.54 seconds, with the solar day of the superterra being 10 hours, 1 minute, and 44.56 seconds. The axial tilt of the planet is 87\*59’00.02”, compared to the rest of the star system, it is directly to the side, like Uranus. The age of the planet is similar to that of the Earth, though it is slightly older, with it being 4.836 billion years old. The gravity on the planet’s poles are 24.192 meters per second, with the gravity on the equator being 23.25 meters per second. The gravity here is 2 times that of the Earth (2.4661 g / 2.3700 g). The circular velocity of the planet is 9.76 miles per second, with the escape velocity of the planet being 13.80 miles.

The planet is observed to have the standard elliptical orbit in its star system, with it parent being a yellow dwarf, with that’s star’s spectrum being G8.9. The planet has an orbital period of 307.328 days, with the semimajor axis of the planet being 0.88 AU. The pericentric distance being 0.88 AU, with the eccentricity being one of the youngest on record, with it being 0.004. A very low amount. The inclination of the planet has been observed to be 1\*28’04.56”. The ascending node of the planet is -46\*30’57.76”, with the argument of pericenter being 126\*45’14.05”. The mean anomaly of the superearth is 161\*25’07.79”, with the longitude of pericenter of it being 80\*14’16.28”. The mean longitude of the planet is 241\*39’24.08”. The hill sphere of this planet is calculated to be 1,535,425.53 miles large, and the confluence sphere radius is calculated to be 1,080,637.23 miles large. The roche sphere for satellites for this planet is 10,980.42 miles. The height of the atmosphere on this planet is 12.63 miles, with the tropopause height of the atmosphere being 7612.81 feet The height of the homogeneous atmosphere being 4993.02 feet, with the atmospheric pressure of the atmosphere being 1.36 AU. The air density of the planet is estimated to be 2.3352 kilograms per cubic meter, with the speed of sound on this planet being 921.12 feet per second.

The exosphere temperature of the planet is 1377.4 kelvin, with the greenhouse effect of the planet being 3.3087 kelvin. The average molar mass of the planet is 35.854, with the relative mass of the planet being 1.8885\*10^-7, with the actual mass of the planet being 1.2203\*10^-6 M⨁. The planet’s atmospheric composition is; Oxygen, with it being 70.1%, Carbon dioxide, with it being 28.4% of the atmosphere, and Sulfur dioxide being 1.44% of the atmosphere. This world is notable for the “Sea Rivers” on the day side, with a massive ocean on the night side. This might be a scar from a collision in the distant past which created a permanent indentation in the crust, and the water simply flowed into the area like what northern Mars might look like once terraformed. This collision might also be the reason why the planet is on to this side, and has a large ring system. The colliding object is estimated to be 2.5 times the radius of the planet’s moon. The size of the ocean on this planet is so large, that it is difficult to get it all into one single photo, with it being around 3 quarters the size of the pacific ocean. A very large crater. The planet even has more gravity then the largest planet in the system, this might be the density difference between the two planets.

### Star System

This planet is part of a 10 planet system and is the 6th in that system. The planet shares the system with another planet with life (marine, terrestrial). Unlike the fifth planet, (the other one with life), this planet does not have a civilization on it, but has more low lying terrestrial life and sea life. This planet’s star system has an evaporating  world as the first planet, with there being 2 dwarf planets in this system. There are 2 sections of the star system, the inner and outer portions of the system, with it being split down the middle, the inner 5 and the outer 5. This star system is also dominated by rocky worlds, with there being only 3 gas giants in the system. The largest planet in the star system is the last world, with it having a mass half of that of Jupiter’s.
