Astronomy on KDE

I recently switched to KDE and Plasma as my main desktop environment, so I
thought I’d start digging into some of the scientific software available on KDE.
First up is KStars, the desktop astronomy program.

KStars probably
won’t be installed with the standard KDE desktop, so you may need to install it. If
you’re using a Debian-based distribution, you can install KStars with the following

sudo apt-get install kstars

When you first start it, KStars asks for your current location, and then it
gives you the option of installing several extra information files to add to
the list of objects that KStars knows about and can display. Once those steps are
KStars begins with the current sky at the location you entered earlier.

Figure 1. On startup, KStars shows you the current layout of the sky in your

So, what can you do with KStars? If you’ve used programs like Stellarium before, you’ll
find that you can do the same types of tasks with KStars. You can use your
mouse to click and drag the display to change the direction you’re facing. The
cardinal directions are labeled along the outside of the circle of the sky, and you can
zoom in and out to change the field of view. If you see an object you want to examine
further, you can
double-click it to center it on the display and tag it as the current object of

Depending on what catalogs of data you installed, some of the objects
may have more or less information available. For example, selecting the planet
Uranus and zooming all the way in shows a reasonably detailed image of the planet,
including the ring orientation.

Quite a few options are available for
controlling what’s shown in the main window. The toolbar across the top of the window
allows you to toggle the following items: stars, deep sky objects, solar system objects,
supernovae, satellites, constellation lines, constellation names, constellation art,
constellation boundaries, Milky Way, equatorial coordinate grid, horizontal coordinate
grid and opaque ground. This allows you to customize the display so that it shows
only what you’re interested in at the time. The last display option is to toggle the “What’s
Interesting” pane.
