Selkoaia

== Selkoaia's information ==
This planet is a temperate marine superearth located in the Milky Way galaxy that was discovered by the SWATH program in 1968. The planet has no observed moons, and life is organic, multicellular, terrestrial, and marine. The planet has one interesting property, and that is that it is almost perfectly round, with its equatorial diameter, average diameter, and polar diameter all being 10,241.15 miles. The planet has a 0 oblateness for some unknown reason, with some on the more conspiracy side of things thinking that this world is in fact artificial. The mass of the planet is three times that of the earth: 1.7981*1025 kilograms, or 3.0107 M⨁. The density of the superearth is 7.6706 grams per cubic centimeter. The insolation of the planet is 1.1481, with the average temperature of the superearth being 234.2 kelvin; for the conversions, it is -38.11 fahrenheit, and for Celseius, it is -38.95. The earthlike similarity of the planet is remarkable considering its almost dead appearance with it being 0.871. The albedo is 0.56129. I am not going to mention the geom, as it seems to be a recurring feature of all the planets I discover.
The rotational period of the planet is very long, with it being 80.581 days long, and the solar day is 284.150 days, triple the amount of the solar day. The axial tilt of the orbit is 0*04’46.93". Due to the perfect roundness of the planet, its gravity is even throughout the entirety of the planet, at 17.647 meters per second. The circular velocity of the superearth is 26,975.81 miles per hour, with the escape velocity being 38,149.55 miles per hour. The age of the planet is older than ours, with it being 5.858 billion years old. The tidal heating of the planet is 1.0484*10^10 watts of energy, or 1.0833 P⨁. The height of the atmosphere of the superearth is expectedly low, with it being only 20.39 miles high. This is due to the mass of the planet being three times that of the Earth. The tropopause is at 4108.40 feet. The height of the homogeneous atmosphere is 13,755.02 feet, and the atmospheric pressure of the superearth is 48.7 atm. The air density of the planet is 66.63 kilograms per cubic meter, with the air temperature being 274.03 kelvin. The speed of sound in this world’s atmosphere is similar to that of the Earth, at 702.58 miles per hour.
The exosphere temperature is 1341.2 kelvin, with the greenhouse effect being 39.81 kelvin. The average molar mass of the planet’s atmosphere is 31.021, with the relative mass being 1.1066*10^-5. The actual mass of the atmosphere is 45 times that of the earth’s atmosphere, with it being 2.1516*10^20 kilograms, or 45.032 earth atmospheres. The atmospheric composition of the planet is natural for any earth-like world, and with it being suitable for some human habitation, of course edited in some ways for regular human habitation, terraforming was necessary for the colonization of this world. The atmospheric composition follows, with oxygen being at the top, making up 71.7% of the atmosphere, or 34.9 ATM. This makes the life on this world a little larger than expected on other worlds that are Earth-like, with life resembling something more of the late Carboniferous and early Permian periods here on Earth. They have developed a very strong stature against the gravity of the planet. Nitrogen comes in at a distant second, with it making up only 27.2% of the atmosphere. 
There is very little carbon dioxide on this planet, with it making up only 0.409% of the atmosphere. The depth of the ocean on this planet seems shallow, as its only 7789.55 feet, and the average molar mass in the ocean is 18,244. The density of the ocean is 1.0025 grams per cubic centimeter. The average temperature of the ocean is the same as the average temperature of the earth, at 274.03 kelvin. The oceanic pressure is 48.7 atm, with the bottom pressure of the ocean being 463 atm. The bottom composition is the usual, being just regular rock. The composition of the oceans are just water with it coming at 99.5%, and the rest being sulfur dioxide with it coming at 0.498% of the atmosphere. The planet orbits a K4.9 star, which is the main star in the binary system that the planet is a part of. The orange dwarf star has a metallicity of 0.40899. The orbital type of the planet is elliptical, with the orbital period being almost only a third of that of the Earth’s year, at only 112.478 days. The semimajor axis of the planet is 0.3944 AU. The pericenter is 0.3839 AU, with the apocenter being 0.4048 AU. The eccentricity is 0.027, the inclination 0*45’54.39", and the ascending node is -20*25’53.19". The argument of the pericenter is 344*39’30.91", with the mean anomaly being 213*32’34.10". The longitude of the pericenter is 324*13’37.71".
