About Stellarium

Stellarium draws an accurate night sky with 600,000+ stars, constellations from many cultures, eclipses and telescope control — like Starry Night, minus the price tag.

Stellarium is completely free and open source (GPL-2.0+) — no trials, no subscriptions, no locked features. Always download from the official website to avoid bundled malware.

Free alternative to: Starry Night (paid)
