Plan your observing session with our companion app — tonight's best targets, go/no-go conditions, moon interference, and export to NINA or SkySafari.
Planetock is free and made with love in northern New Mexico. If you enjoy it, a small contribution keeps the stars aligned.
Your sky, as a clock. Planetock shows you where every planet, the sun, and the moon are right now — oriented to where you're standing, updated every second.
