Homebrew Aerth
PLANETARY SYSTEM
The heavenly bodies in the sky "close to Aerth" are numerous, a lone satellite and nine planets, many with their own orbiting satellites. Some of these may even harbor creatures and be accessible by various magical means.
Celene: Aerth's Moon — Orbiting Aerth every 30.007 days, it rotates at a leisurely pace of once every 94.3 days. Mostly rock and dust it is still geographically active with celenequakes occurring every few decades. Occasional meteor strikes along with its non-existent atmosphere and low gravity allows for interesting nighttime views for the keen-eyed.
Pel: Yellow dwarf star (G-type main-sequence) — The life-giving orb at the center of the Pelar system, it fuses hydrogen and helium for energy, and contains trace elements of carbon, neon and iron.
The mean distance from Aerth is roughly 156,000,000 km and light takes approximately 8 min 25 seconds to arrive.
Pyremus — The closest planet to Pel, it orbits the star every 77 Aerth days, and is tidal locked all but stopping its rotation altogether, needing over 400 days to rotate once. There are some nomadic inhabitants along the terminus which slowly follow the setting or rising sun indefinitely.
Bereia — The second planet from Pel, it orbits the star every 232.3 Aerth days, but its day is longer than Aerth at a fraction over 30 hours.
The orb is hot, humid, and filled with mega-flora and mega-fauna as its low gravity, slow rotation and proximity to the star makes for an uncomfortable but lush environment.
Faulkanen — The fourth planet is a volcanic landscape of ash and lava flows with a semi-toxic atmosphere. Inhabitants are known to be elementals or outsiders from the lower planes, and the few cities that exist are best left for the mighty or foolhardy. One known portal to this hellish landscape exists near an active volcano off the coast of Beroea. Its orbit takes 712.5 days, a day lasts 28 hours, and it has one large icy moon, Korden.
Olidammar — The fifth planet is a small rocky world with no atmosphere and a small rocky and jagged moon, Rudda. Both bodies are thought to be mostly hollow and/or crawling with tunnels with insectoid inhabitants. Orbiting Pel takes 1664 days and its day lasts 41 hours.
Myrha — Sixth planet from shining Pel, this violet ringed world is the second largest gas giant in the Pelar system. Multiple icy rocks in the ring surrounding Myrha are inhabited, as are some of the fifty-seven moons. One orbit around Pel takes 12.7 years, but its day is a speedy 11.1 hours causing it to bulge at its equator.
Ista — The largest of the planets, Ista is a massive gas giant with a singular floating city in its high clouds. Seventh from the star, it has twenty-nine moons in orbit, and it is assumed that at least a handful are inhabited. Its orbital period is 28.73 years and rotates every 14.2 hours.
Boccab — More an ice giant than gas, this blueish ringed planet lies far out in the system as the eighth planetary body orbiting Pel. Massive rings and eighteen wide-ranging moons surround the world; and Boccab’s inhabitants are believed to be elemental in nature. Second slowest in the night sky, it takes a leisurely 77.6 years to make its orbit and rotates at 19.5 hours.
Syra — The ninth and last real planet of the system is Syra, a rocky and pitted planet lacking any atmosphere. Two moons orbit it in long ellipses, both matching its parent being rocky and pitted. Typha, the largest of the two is thought to have an underground cave network and bizarre cities occupied by ancient race, and Kysus is rumored to have a sprawling necropolis of unspeakable horror. Syra takes its time orbiting Pel to the tune of 213 years, and rotates once every 4.4 days.
