## Calaina's information

This is a temperate terra with intelligent life, and it was discovered in the early 2010s in August of 2013. The planet has a diameter of 13515.33 miles, or 1.7051 R⨁, with a mass of 4.4891\*10^25 kilograms, or 7.5141 M⨁, which is 7 1⁄2 times more than the mass of the Earth. The density of the planet is 8.4011 grams per cubic centimeter, with the oblateness being 0.00826945. The effective temperature of the planet is 266.42 kelvin, 19.886 degrees Fahrenheit, or -6.73 degrees Celsius, with the earth similarity of the planet being 0.822. The albedo (bond / geom) is 0.313294 and 0.375953. The rotational period of the planet is 12 hours, 20 minutes, and 7.28 seconds, with the solar day being 12 hours, 22 minutes, and 38.82 seconds. The axial tilt of the planet is 0\*40’4.55”, with the age of the planet being around that of the Earth at 4.566 billion years old. The gravity on the poles is 25.778 meters per second, with the gravity on the equator being 25.136 meters per second. (2.6278 g / 2.5623 g). The circular velocity of the planet is 10.32 miles per second, with the escape velocity of the planet is 14.59 miles per second. The planet has an elliptical orbit, with the parent object being a star smaller than that of our Sun. The orbital period of the planet is 151.128 days, with the semimajor axis being 0.51 AU. The pericentric distance of the planet is 0.50 AU, with the eccentricity being 0.035. The inclination is -1\*15’15.73”, with the ascending node being -157\*49’17.62”.

The argument of pericenter is 311\*12’27.73”, with the mea anomaly of the planet being 224\*57’25.45”. The longitude of pericenter is 153\*23’10.11, with the mean longitude being 378\*20’35.56”. The hill sphere radius of the planet is 974117.69 miles, with the influence sphere radius being 724466.52 miles, and the Roche limit for satellites is 11546.85 miles. The height of the atmosphere on the planet is 10.34 miles, with the tropopause height being 18393.05 feet. The height of the homogeneous atmosphere is 6492.87  feet, with the atmospheric pressure being 27.4 atm. The air density of the planet’s atmosphere is 46.074 kilograms per cubic meter, with the air temperature being a high 294.68 kelvin, 21.53 degrees celsius, or 70.754 degrees fahrenheit. On Earth, our average temperature is 53 degrees Fahrenheit, which makes this world warmer than our own with it feeling like the Summer all year long even in the coldest of months on this planet. These conditions have made the planet a holiday resort for the Humans of the far future who have already well colonized this world.

The speed of sound on this world is 930.08 feet per second, with the exosphere temperature being 1413.6 kelvin. The greenhouse effect on this world is 23.807 kelvin, or -416 degrees fahrenheit. That does not seem that much, but it is only 10 degrees below out planet’s greenhouse effect. The average molar mass of the planet’s atmosphere is 42.213, with the relative mass being 3.2826\*10^-6, with the mass of the atmosphere being 2.4666\*10^-5 M⨁. The atmosphere of this world is slanted to one element and that is carbon dioxide, which is 85.5% of the atmosphere, with oxygen being 14.2% of the atmosphere. Sulfur dioxide makes up the rest at 0.33%. This world is dominated by two large continents, and their smaller islands. Both of the continents are generally flat, with plenty of coniferous forest, similar to that of Missouri or Eastern Texas. The planet has no moons, though it might have had a dwarf moon at one point, due to the writings of the civilization that inhabits this world, that describes an asteroid looking object that orbited the -

planet that gradually got farther away until at one point god took it away, though it most likely is not a god and is instead a moon that got far enough that the planet’s gravitational pull could not keep it anymore. This was also a temporary moon that was captured at one point in the past millions of years ago. The planet’s civilization had domesticated what this world would call a horse, and have used it for thousands of years, and they have bred it to the point that motorized vehicles are not that popular for any sort of long distance travel. The civilization that inhabits this world has a population larger than ours with it being estimated to be 70 billion, which can be seen by the metropolis at night, and the massive farms at sea and on land, with the former fields that are the size of Texas, being turned into agricultural land. This can be seen from space in the form of large pastel brown streaks on the surface. The colonization of the seas seems to be underway.

### Moons

There are no moons around this planet though there might have been one in the past.

## Star System

This planet is part of a 6 planet system with 2 dwarf planets. There is only one gas giant in this star system, with it having a mass of 0.58871 M♃. The mass of the central star in the system is 0.79561 M⨀, and it is an orange dwarf star. The first planet in the system is a hot selena, with the second planet being a hot gas giant/subgiant. The third planet is a hot desert that has a mass larger than that of the Earth’s, and the fourth planet is this one, a temperate superterra with multicellular life. The fifth planet is a dwarf planet and is a cold Selena, with the sixth planet being a cold ice world and also a dwarf planet. There is no asteroid belt in the system and there is a spread out version of an oort cloud. The closest star system to this one is a 6 planet system that orbits a lone red dwarf. The star system is split into two parts, the inner system, which includes the first 3 planets, and the outer system, which includes the last 3 planets. The first planet has a brownish color, with the second planet, a gas giant, having a pale pinkish-yellow pale color combined with a blue atmosphere. The third planet has an orange color and has a thick atmosphere. The fourth planet, this one, is the most earth-like in the system, and the fifth planet is a small barren icy rock with one major moon around it. The sixth planet is less interesting with it being a featureless icy ball that looks like europa.
