Mylor is an Earth-like planet that lies in orbit around a star remarkably similar to our own, classified by our scientists as "18 Scorpii". It is located approximately 45 lightyears from Earth. A high-speed Mylorian starship can cover this distance in approximately 20 days at maximum speed.
Unlike most planets, Mylor’s axial tilt is nearly zero degrees (0.006, to be exact). Because of this, the planet’s equator always faces its star, and the planet is devoid of any seasonal changes throughout its year. This causes the climate areas on the planet to be exceptionally steady and uniform. The only variations are caused by the planet's distance from its star, which fluctuates by approximately 4% between its closest and furthest points.
Mylor’s atmosphere contains large amounts of nitrogen, neon, and oxygen, as well as trace amounts of argon and other minor gasses. Mylor’s oxygen concentration is around 17%, which is enough to sustain most visitors, albeit causing bouts of shortness of breath from time to time.
Mylor’s dense atmosphere, which is more rich in greenhouse gasses, holds in considerable heat. This increases the rate of evaporation across the planet’s oceans, lakes, and rivers, which in turn leads to a high precipitation rate across most of the planet. As a result, the bulk of Mylor’s land masses is covered in lush, dense vegetation and high humidity. Most of Mylor has a tropical feel to it, and even near the poles the humidity remains fairly high. Only at the very tips of the planet’s poles does ice form, and the frozen caps found there occupy less than ten percent of the planet’s total surface area.
Mylor is approximately forty percent land by area, with the remaining sixty percent taken up by small polar ice caps, oceans, and lakes. Eons of constant rainfall have formed thousands of rivers across the land masses of the planet, and the steady erosion has worn down most mountains, resulting in a planet that is overall covered in smooth, sloping mountains rather than rocky crags, with many rivers forming spiderweb-like shapes across the larger continents.
