A first look at the Phoebe system- the star system in which the planet of Dionysus is found.
An important note is that while in science most exoplanets aren't really named like this anymore, the Society Of Human Sciences has determined it will make an exception in honor of the monumental discovery on Dionysus- a call back if you will.
The star this system is named after is an orange dwarf with a mass of about 0.8.
The first planet in the system, Hephaestus is the closest to its star and tidally locked- it has moons, though it's thought to have had one at some point. What remains of this potential moon is now simply a faint ring surrounding the planet. Hephaestus lacks an atmosphere, and the star facing side seems to have been scorched- the surface of Hephaestus' day side is approximately 1'100 Celsius (or 2,000 degrees farenheit.) while the night side is -200 Celsius (or-330 farenheit). Like all tidally locked planets there is a Terminator zone however.
On the night side, what atmosphere was there has long sense frozen and solidified, while the day side had it stripped away. The planet is subject to intense solar winds.
The second planet in the Phoebe system is Dionysus: the darling of the Society. Dionysus is this far the first- and only exoplanet confirmed to be inhabited. It's an earthlike planet- with 0.8 M. Despite it's smaller size it has 20 percent stronger gravity on earth, due to having a large core abundant with heavy metals. It has a thick atmosphere which tints it that golden-orangish color. The planet also has not one- but three moons! The largest of the moons is called Ariadne, and is around the size of Earth's moon, the two smaller moons are Eurymedon and Philasos. A pair of moons most comparable to Mars' Phobos and Deimos.
Dionysus is getting its own post so we won't go into it too much here.
The last of the rocky planets in the Phoebe system are Castor and Pollux- a pair of binary planets orbiting each other.
Pollux is slightly larger than mercury, while Pollux is 10 percent larger than earth. Pollux' surface is covered in- and perhaps primarily composed of ices and slushes, with ammonia being the primary component. Pollux is composed primarily of ices.
Beyond the belt of the Phoebe are the two known gas giants-
Hyperion is a giant only slightly larger than Jupiter with a similar atmospheric makeup.
Chione is a Neptune or Uranus sort of planet, made up of methanes, ammonias and hydrogens.
There is not much known about these two ice giants, other than their large amount of moons similar to our own. We have yet to fully investigate this system.
