Boron

Boron is the undisputed titan of the Illiós system, a majestic gas giant and the outermost planet in the stellar family. Its sheer scale dominates the distant, icy reaches of the system, acting as a gravitational anchor for the smaller, inner worlds. As a gas giant, its form is a swirling maelstrom of colorful cloud bands and immense storms, a true spectacle to behold from the deep void.  

Physical Characteristics

With a radius of 78,814 km, Boron is a behemoth, clocking in at 12.4 times the size of Earth. This makes it the largest planet in the system. Its mass is equally impressive, estimated at 509 Earths, which is equivalent to 1.6 times the mass of Jupiter, our own solar system's largest planet. This immense mass and size give Boron an incredibly powerful gravitational pull, shaping the orbits of smaller comets and asteroids far out in the system.  

Composition

The atmosphere of Boron is a chaotic blend of volatile gases under incredible pressure. The primary component is hydrogen, making up 75% of its atmospheric volume. The planet’s distinctive greenish-blue hue is attributed to the presence of methane, which accounts for another 16%. The remaining notable component is nitrogen, comprising 6% of the atmosphere. The intense pressure and temperature within its core are theorized to compress these gases into exotic states of matter which has proved a fascinating area for astronomers across the system.
