1 PS-21g description
Planet PS-21g is the 6ths farthest planet from the star in the fictitious solar system. It is 5.2 astronomical units. The radius of PS-21g is 26000kms around the equator. The planet has an atmosphere that is not yet detailed at this point. The density of the planet is 1.3(gm/cm3). The planet rotates on its own axis, and it takes 14 hours. Thus, planet PS-21g days are 14 hours long. PS-21g has 2 large moons, 4 medium ones, and many small ones.
2 Logical conclusions from the data about PS-21g
Planet PS-21g has the 6th longest orbital period in the solar system. The planet is 5.2 astronomical units from the star, and since the distance from the star is directly proportional to orbital periods, the planet has the 6th longest orbital period.
Planet PS-21g has the second-fastest rotational speed in the solar system. its days are 14 hours long for a planet with a 26000km radius. It is very likely that the planet has an equatorial bulge stemming from the centrifugal speed around the equator. If a planet like the earth with almost a quarter of the radius of the PS-21g and nearly twice as long days has an equatorial bulge, then PS-21g is likely to have a spheroid shape because of the bulge at its equator. Additionally, the radius also has an impact on the gravity of the planet. There is a positive correlation between a planet's radius and its force of gravity. The radius determines the distance from the center of the planet, and the longer the radius, the gravity reduces. Therefore, it is possible that the radius of the planet is weak owing to the large radius, which is almost 4 times that of planet earth. Secondly, it has a very low density. Higher density means that the object experiences a stronger gravitational pull because it is closer to the center of mass. There is a direct proportionality between density and size of the planet. the denser the planets are, the smaller their radius, the denser the planet. The denser the planet, the more likely it has a stronger force of gravity.
Planet PS-21g has several moons. This means it has a considerable gravity to maintain two large, four small, and many small moons in orbit. The configuration of the moons and distance from the planet is not disclosed, but it is likely to cause a few effects on th...
