## Citrus's information

This planet is a megajupiter located in the Milky way galaxy that was discovered on March 1st, 2017. The planet is a hot megajupiter, its the fourth in its star system, and has an observed 28 moons around it. There are 2 terras that orbit this megajupiter that manage to have water in an environment that would evaporate their water. The planet has a radius of 44705.35 miles, or 11.28 times that the radius of the Earth. The mass of the planet is 10 times that of Jupiter’s, or 10.404 M♃, thats 1.9755\*10^28 kilograms. The density of the planet is 12.784 grams per cubic centimeter, with the oblateness of the planet being 0.00934958, very low. The effective temperature on the planet is 226.92 kelvin, a low temperature for a “hot” world, though the average temperature for the world is 548.07 kelvin, the conversions for that is 274.92 degrees Celsius, or 526.856 degrees Fahrenheit. The Earth similarity of the planet is 0.272, the planet’s similarity is unexpectedly high, with the expected range being from 0.050 - 0.120 due to it being essentially a traditional hot jupiter. The albedo of the planet is 0.50425, or 0.6051. The rotational period for the megajupiter is 7 hours, 29 minutes, and 36.58 seconds, while the solar day of the planet is 7 hours, 29 minutes, and 43.32 seconds.

The planet is surprisingly young, with it being only 15.571 million years old, this could explain the planet being so scorched. The gravity on the poles is 259.78 meters per second, with the gravity on the equator being 251.04 meters per second. The circular velocity of the planet is 84.15 miles per second, with the escape velocity of the planet being 119.01 miles per second. The planet has an elliptical orbit, with the parent object being a F4.1 star, a white dwarf, that has a radius twice that of the sun, as it seems to be spinning fast enough that it has become an egg over a relatively short period of time. The planet has an orbital period of 3.422 years, with a semimajor axis of 2.68 AU. The pericentric distance of the planet is 2.51 AU. The eccentricity of the planet is 0.063, with the inclination being -2\*28’57.72”. The ascending node is -48\*33’19.78”, with the argument of pericenter being 326\*18’06.07”. The mean anomaly is 11\*34’24.21”, with the longitude of pericenter being 277\*44’46.28”. The mean longitude is 289\*19’10.50”, with the hill sphere radius being 0.32 AU. The influence sphere radius for the planet is 0.35 AU, with the roche limit for satellites being 87829.39 miles. The height of the atmosphere in this world is 173.93 miles high, yes a very short distance, with the tropopause height being 6579.70 feet. The height of the homogeneous atmosphere being 46.03 miles, with the air density of the planet being 5364.7 kilograms per cubic meter. The air temperature of the planet is 5,000 kelvin.

The speed of sound in this world is 3.18 miles per second. That might be slow when reading that, but the speed of sound per hour is 11,448 miles per hour. The exosphere temperature on this planet is 1624 kelvin, with there being no greenhouse effect on or in this world. The average molar mass of the planet’s atmosphere is 2.201, with the mass of the planet’s atmosphere being 9.7395 M♃. The planet’s composition goes as follows, Hydrogen comes in at 93.2%, Helium comes in a distant second with it being at 6.44%. Methane is the lowest with it being only 0.282% of the atmosphere. The special thing about this megajupiter is that it has 2 moons which are also terras. These two moons seem to be only terras at the moment and might become frozen wastelands or scorched deserts like the first moon in the system. These moons might be warm because they are still heated by their initial formation, though there is a third option and that the megajupiter and the two terras might be in a temperate zone, meaning that they will level off at a livable temperature in the distant/near future. There are not that many mentions of the planet in online spaces besides it being the “Funny orange planet” aa its name is “Citrus”, the name of a type of orange, and despite popular opinion the planet is not orange, but is instead pink/purple.

### Solar System

The planet is the fourth in its system, and is part of a system that has an egg star, the star is super young so that might be the explanation for why it's spinning that fast. It shares the system with a 4 earth mass terra with rings, and a gas giant slightly larger than Jupiter, along with some other worlds.
