Astronomy is a natural science that studies celestial objects and phenomena. In the known world, astronomy plays a role in keeping track of time as well as religion.
The science of astronomy is studied by the sapiarchs of the College.
The Sun and Moons[]
It is known that daytime period is correlated with the seasons. Towards the end of summer, the days start to grow shorter, a trend which continues through autumn.
The known world is orbited by two moons in a similar fashion to Earth's. There are twelve moon turns to a year, as on Earth. Even on our Earth, years have nothing to do with the seasons, or with the cycles of the Moon. In the world of Nirn, a year is a measure of a solar cycle, i.e., of how long it takes Nirn to make one complete revolution around the sun.
Planets[]
There are several other planets in the sky over the known world, which some sapiarchs believe to be representative of planes of Oblivion, or more contraversially, literally representative of the eight Altmeri gods.
Stars and Constellations[]
Constellations are the names given to a group of stars linked close together. Often times, they represent some sort of picture. Their names usually vary between the various peoples. There are thirteen constellations identified by the sapiarchs of the College.
