## Carola's information

Located in the M 101 galaxy, this temperate marine earth with intelligent life that  was discovered on April 8th, 2030 is in a binary system with a subearth. The equatorial diameter of the temperate marine earth is 7318.30 miles, with the average diameter of the planet being 7284.84 miles. The polar diameter of the planet is 7218.39 miles, with the oblateness of the planet being 0.013651, a very low amount though not unexpected. The mass of the planet is 5.3178\*10^24 kilograms, or 0.89039 M⨁, pretty similar to that of the Earth’s mass though Earth would still beat it in a collision. The density of the marine planet is 6.3026 grams per cubic centimeter, with the insolation of the planet being 0.92171. The effective temperature of the planet is 224.33 kelvin, here are the conversions, for celsius its -48.82 degrees, and for Fahrenheit, its -55.876 degrees. The average temperature of the planet is 290.47 kelvin, with the temperature conversions being 63.176 degrees fahrenheit, and 17.32 degrees celsius. The earth similarity index of this planet is 0.961, a high amount, with the albedo of the planet being 0.54. The rotational period of the planet is 11 hours, 6 minutes, and 57.39 seconds, with the solar day of the marine world being 11 hours, 10 minutes, and 20.49 seconds. The axial tilt of the planet to its orbit is 81\*04’40.57”.

The gravity on the equator of the planet is 10.098 meters per second, with the gravity (mean) being 10.314 meters per second. The gravity on the poles tend to be 10.505 meters per second. The circular velocity of the planet is 17433.63 miles per hour, with the escape velocity of the planet being 24654.88 miles per hour. The planet is older then the Earth, with it being 7.262 billion years old, an old world with an old civilization to boot. The tidal heating of the planet is 1.0759\*10^12 watts, or 0.95598 P⨁. The additional information of the planet’s tidal heating is that the heating per cubic meter is 0.002469 watts, or only 14.352 kelvin. The planet is also tidally locked with its star, or moon, both are likely, but it seems to be tidally locked with its moon, as the star is too far for it to be tidally locked with that, and on the planet’s and moon’s surface, one side of each is always visible throughout the year.The height of the atmosphere of the planet is 51.52 miles, with the tropopause height being 13.71 miles. The height of the homogeneous atmosphere is 28545.79 feet. The atmospheric pressure of the atmosphere is 11.2 ATM, with the air density being 12.726 kilograms per cubic meter. The air temperature of the planet is 289.22 kelvin. The speed of sound on this world is 770.25 miles per hour, with the exosphere temperature being 1205.9 kelvin. The greenhouse effect of the planet is 66.125 kelvin. The average molar mass of the planet’s atmosphere is 27.457, with the mass of the planet’s atmosphere being 9.1145 earth atmospheres.

The atmospheric composition starts with Nitrogen, with it being 82.3% of the atmosphere, then Oxygen comes in a second place with it being 13.9% of the atmosphere. Water vapor comes in at third with it being 3.21% of the atmosphere. Carbon dioxide comes in a small fourth of the atmosphere, with it being 0.524% of it. The oceans on this marine earth have a maximum depth of 24903.27 feet, with the average molar mass being 18.016. The temperature of the oceans is around the same average temperature of the rest of the planet at 289.22 kelvin.. The atmospheric pressure of the oceans is 11.2 atmospheric pressures (ATM), with the bottom pressure of the oceans being 784 ATM. The planet has an elliptical type orbit and orbits the main star in the binary star system that its part of. The orbital period of this planet is surprisingly short, with it being only 91.728 days. The semimajor axis of the planet is 1155.7671 miles, with the pericenter of the planet being 1155.7412 miles, and the Apocenter being 1155.7930 miles. The planet has no eccentricity, with it having a perfect 0.000. The inclination of the planet is also very low with it being only -0\*04’41.68”, didn’t know that a negative zero was something possible, The ascending node of the planet is -61\*01’27.41”, with the argument of pericenter being 54\*37’23.75”. The mean anomaly of the planet is 160\*34’56.40”, and the longitude of pericenter is -6\*24’03.66”. The mean longitude of the marine earth is 154\*10’52.74”, with the orbital velocity of the planet is 653.29 miles per hour. The orbital resonances of the planet are 7:2 (A5). The hill sphere is 357072 miles, with the influence sphere being 233982 miles. The Roche limit for satellites is 5672 miles. Not that large. The planet is not mentioned in pop culture and media, but it was the main topic of the Space Engine music video “Frontier 2105” a spacewave/chillwave video which was a playlist of songs while a video of the planet was shown in the background. It was released in early 2031.

### Solar system

The solar system that the planet is a part of is a binary system of a red dwarf and an orange dwarf. The system contains many planets with the total number being 19 planets, with 2 of the planets having life. The system is located on the outskirts of the M 101 galaxy and is one of many and would not appear on that many maps of the region until it was discovered in 2030. The system also only has a radius of  328 AU, typical for a binary system.
