Ceuryallius and Ceranciulium

(*This one has a bit of a long name*)

## Ceuryallius and Ceranciulium's Binary Information

This is a binary between two planets, terras, with one of them having life and the other not. These two planets are the fourth in their system and were both discovered during 2014. They are located inside of Kayle’s galaxy and they orbit an orange dwarf star. The farthest distance between the two planets is around 19 - 20 hundred thousand miles. One of the planets is a carbonia, with the other being an oceanic part-carbonia. Both of the planets have a mass 2+ M⨁, with both having a diameter larger than that of the Earth.

### Moons

The "Moons" of the binary planets are the planets themselves (As SE classes them), though there not any actual moons around these two planets.

The axial tilt of the planet is 37\*37’32.20”. The age of the planet is 3.861 billion years, which is a young planet with multicellular life, though the life is only marine. The gravity on the planet is not perfectly uniform despite the perfect oblateness, with it being 16.039 meters per second on the poles of the planet, with the gravity on the equator being 16.038 meters per second. The circular velocity of the planet is 7.18 miles per second, with the escape velocity being 10.16 miles per second, which is almost double that of the Earth’s. The planet has a semimajor axis of 63890.61 miles, with the pericentric distance being 43158.69 miles.  The eccentricity of the planet is 0.324, with the inclination of the planet being -27\*26’08.62”. The ascending node of the planet is -91\*09’48.30”, with the argument of pericenter being 106\*16’25.31”. The mean anomaly of the planet is -105\*23’59.61” , with the longitude of pericenter being 15\*06’37.00”. The hill sphere radius of this planet is 490615.02 miles, with the influence sphere radius being 373985.63 miles.

The height of the atmosphere on this superterra is 20.48 miles, with the tropopause height being 28352.21 feet. The height of the homogeneous atmosphere on this planet is 11261.45 feet, with the atmospheric pressure being 10.6 atm. The air density of the planet is 18.553 kilograms per cubic meter, with the air temperature being 287.53 kelvin, with the conversions for that being 57.884 degrees fahrenheit, or 14.38 degrees celsius. The speed of sound on this planet is 911.26 feet per second, with the exosphere temperature of the planet being 1182.6 kelvin. The greenhouse effect on this superterra is 16.648 kelvin, with the average molar mass being 43.965. The relative mass of the planet’s atmosphere is 3.1705\*10^-6, with the mass of the atmosphere being 8.8406\*10^-6 M⨁. The atmospheric composition of the planet contains 99.8% carbon dioxide, 0.185% oxygen, and 59.9 parts per million sulfur dioxide. Nitrogen, Argon, and Water vapor all make up the rest of the atmosphere. The life on this planet is strictly marine and it is multicellular, with life showing signs of moving onto the land. The biosphere of this world is split into two parts, the deep dark and the oceanic surface.

Most diverse life on this world is part of the oceanic surface with large coast spanning reefs existing in the oceans in common place, Ceuyspecius-homo, is a fish species that uses 2 large prongs to help it dig into nests of oceanic insects known as Ceuyralliusian-insectovia, and Megaliwhales, which are massive creatures that survive off of this world’s version of krill. Deeper in the ocean, creatures get less diverse and start to be more plant-like, with large tree-like structures that survive off the thermal heat of the core through lava plumes and undersea volcanoes. The landmasses of this world, though lacking life, are somewhat interesting, with most of the continents containing river systems or large lake structures similar to that of the great lakes. The continents are composed of deserts and large sand-based beaches, which therefore makes them arid. Algae however does spread far inland through rivers, and some species from the upper sea level seem to be starting to evolve amphibian qualities. By the time that humanity arrived on this world, 2 billion years from now, a small-scale civilization, with the technological level of the medieval era, has evolved. However the planet presently is in the stage of the Earth when life was on the edge of reaching land.

(4th) 1st

Ceranciulium is the smaller of the two planets, and is also the more oceanic, though it also does not have life of its own. It is considered a “terra” even though there is only one landmass on this entire world. The oceanic terra has a radius of 9625.17 miles, or 1.2143 R⨁, with the mass on this world being 1.2887\*10^25 kilograms, or 2.1572 M⨁. The density of the planet is 6.622 grams per cubic centimeter, and this world also has a perfect oblateness, though this also seems to not be entirely true due to the gravity of the world not being uniform. The effective temperature of the planet is 254.64 kelvin, with the conversions for that being -18.51 degrees Celsius, or -1.318 degrees Fahrenheit. The earth similarity of this world is 0.911, which is not expected considering the lack of large landmasses. The albedo (Bond / geom) is 0.385874, and 0.463049. The rotational period of the planet is 5.941 days, though it is also tidally locked, with the solar day of the planet being 6.495 days. The axial tilt of the planet is 37\*37’32.20”, which is the same axial tilt of its larger brother. The planet has a standard elliptical orbit, with its “parent” body being Ceuryallius. The orbital period of the planet is 5.941 days, which is the same as its rotational period. The semimajor axis of the planet is 82587.41 miles, with the pericentric distance being 55788.55 miles. The eccentricity of the planet is 0.324, with the inclination of the planet being observed to be -27\*26’08.62”. The ascending node of the planet is -91\*09’48.30”, with the argument of pericenter being -73\*43’34.68”. The mean anomaly of the planet is -105\*23’59.61”, with the longitude of pericenter being -164\*53’22.99”. The mean longitude of the planet is -270\*17’22.61”, with the hill sphere radius of the planet being 29335.45 miles. The influence sphere radius of the planet is 59262.46 miles, with the roche limit for satellites being 7617.25 miles.

The planet also has a larger orbit than its larger brother, with this being due to the smaller mass of the planet. The height of the atmosphere on this world is 15.13 miles, with the tropopause height being 28925.92 feet. The height of the homogeneous atmosphere is 9897.29 feet, with the atmospheric pressure of the planet being 38 atm. The air density of the planet is 88.937 kilograms per cubic meter, with the air temperature of this oceanic terra being 292.89 kelvin, 67.532 degrees fahrenheit, or 19.74 degrees celsius. This planet has a higher temperature than its larger brother, which seems to be a broad line for oceanic planets. The speed of sound on this word is 788.25 feet per second, with the exosphere temperature being 1183.7 kelvin. The greenhouse effect of the planet is 16.165 kelvin, with the average molar mass of the planet’s atmosphere being 59.498. The relative mass of the atmosphere is 1.4205\*10^-5, with the mass of the atmosphere being 3.0642\*10^-5 M⨁. The atmosphere is 77.3% sulfur dioxide, 22.5% carbon dioxide, and 0.102% nitrogen. Despite it being called a terra, this planet is not really a terra, as stated before, this world has only one large landmass on its surface, this landmass is an arid landscape which has seemed to have been formed from the collision of three tectonic plates. This landmass is made up of several lakes, and it has one large central sea, with that sea having a few islands in it. This landmass is one large desert, with sand dunes covering cliffed mountains that are being slowly eroded. It is also like a triangle in its formation, with it roughly following a three pointed formation. The planet’s oceans are greenish in color, which is unusual as most oceans are either blue or a different color due to the contents in that ocean. There could be more salt in these oceans, or they could be made up of a different material other than water. What that liquid is is unknown. The planet is reflective enough that it can slightly light up the night side of its larger brother.

## Star System

The star system that these two planets reside in is an 11 planet system that orbits an orange dwarf star. The star has a spectrum of K9.4 V, with its diameter being 652344.53 miles, 0.7542 D⨀, with the mass of the star being 0.57679 M⨀. The star system has a hot jupiter, though not the kind that is glowing yellow, with that giant having only one major moon. The first one in the system. There is only one dwarf planet in this star system, it is the 6th in the system. The last planet in the star system and also the largest both by mass and radius, is a superjupiter that has a “large” ring system and a large moon system. It also has a few moons, one of them being a supermoon, a scorched one. This moon illuminates the superjupiter which is rare for moons but common with large scorched moons. The size of the star system’s planetary system is 19.85 AU, with 5 planets being within the first astronomical unit, which in our star system would be 5 planets in the distance between the Earth and the Sun. The 9th planet in the star system has an interesting set of colors for its ring system, purple, pink, and green.
