Getting Started

First, there are a few things you need to know about using Stellarium. You might look at the Stellarium Tour on their website for an overview and reference to these options:

Finding Stars and Constellations

Stellarium starts with the sky as it is now, and you may run the clock forward or set the time for about an hour after sunset to see the night sky for the current season. In this lab study we will go through the seasons in sequence for the northern and the southern hemisphere, and help you find your way around the sky.

Bright Stars

Winter begins in late December for the northern hemisphere, or late June for the southern hemisphere. You can consult the list of stars and constellations at the bottom of this unit to see what should be visible then. Let’s set set the time to 7 P.M. on January 15, when the sky is dark and stars are clear and bright.


Turn off the equatorial grid if you still have it on, and turn on the constellation names and outlines (use the lower menu or press C and V). Let’s find some of the easily identified constellations in the northern sky for each season.

Looking from the South

The following is a guided tour of the sky from the southern hemisphere to see how the sky would change if we moved our point of view to a southern latitude. From the north pole of the Earth you can see only the half of the sky that is north of the Earth’s equator. Your horizon is the celestial equator.
