Manta

Manta is the fourth planet of the Odjoran system. It is a large Gas Giant and orbits just beyond the outer edge of the Odjoran Asteroid belt, about 5 AU from Odjor.

Composition
Manta is a huge planet, with 1.61 times the mass and 1.32 times the size of Jupiter, and functions as the system's heavy Jovian who protects the inner planets from comet and asteroid impacts with its massive gravitational pull. Manta is a typical gas giant composed of almost 93% Hydrogen and 7% Helium.

Manta has at least 11 distinct cloud bands, though lacks any spots, enormous gas storms on the planet.

Moons
Being of such mass Manta wields a massive lunar system in turn, the planet has a total of 54 moons, 6 of which are larger then 1000 km. The total mass of its lunar system is roughly 1.32 M🜨.

Ideme
Ideme is the first of these moons. Ideme is in a close orbit and resembles the moon Io. Ideme has vast Methane seas.

Tora
Tora is the second of these moons. It's rather large, having a diameter of 8400 km. However, it's only Manta's third largest moon. Exotic unicellular life lives on this hot moon which is covered with methanol seas.

Seanna
Seanna is the third and largest of the moons. Its diameter is almost 12000 km. Its mass barely exceeds 0.36 M🜨, however. It's surface is entirely covered with water. making it an ocean planet. The moon also interestingly has a small ring system.

Hira
Hira is the most massive of all the moons it's heavier then all the other moons at 0.43 M🜨, it's size while still being over 10000 km in diameter, gives it in combination with its mass the capacity to hold a dense 4.97 atm atmosphere.

Teth
Teth is the fifth of these moons. It's much colder then the others, being frozen ice world that harbours a subglacial ocean of liquid water.

Tritune
Tritune is the last and smallest of these moons. It is the only known moon to have a submoon, Eruti, in orbit.

Trivia

 * Manta is loosely based upon XO-4 b.
 * Manta was designed to function like a much stronger Jovian then Jupiter in our solar system.
 * Manta originally had a seventh moon called Wampor, it was later replaced by Teth.
