Install Checklist

Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
File size is a light 11.93 MB, so it installs quickly even on modest connections.
This build is signed by "F-Droid Open Source" — always verify the developer name matches what's listed on the app's official store page before installing an update.
After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

About this app

Planetario contains a 3D model of our solar system. It will show the horizon and the planets in their path along the sky. The word planet comes from the Greek planetai, meaning "wanderers". Because of the rotation of the earth, the stars seem to move in perfect circles, but the path of planets seem to wander against the background of stars.

Although there are many other apps and websites that show our solar system much more acurate, Planetario has a combination of features you which make it unique:

* Speed up time to see and understand the path of the planets through the sky
* Zoom in on planets using a virtual telescope
* See the horizon from all places on earth: checkout the different path of the Sun seen from the Northern and Southern hemisphere
* Travel the Moon or another planet to see the horizon from there. Visit the Apollo 16 and Mars Opportunity landing sites.
* See the earth from the Moon as seen by the astronauts John Young and Charles Duke
* Check whether the Earth and the Moon can be seen from Mars as separate 'stars'
* Visit some far away virtual spacestations to look down on our solar system or see it from the side.

Planetario may help you to:
* Learn where you can spot the planets in the night-sky
* Understand why the planets wander along these strange paths
* Get a grasp for the vast emptyness between our planets, and their tiny size compared to the size of our solar system

Frequently Asked Questions

Is Planetario free to download?
Yes. The APK file linked from this page is free. The developer may offer in-app purchases once installed, but obtaining the installer itself costs nothing.

What Android version does Planetario require?
Android 4.1+ or newer. Installing on older devices may cause crashes or refuse to install.

Is Planetario safe to install?
We link to the exact APK published by F-Droid Open Source. We do not modify the file. Still, as with any sideloaded app, scan it with a reputable antivirus before opening it, and only grant permissions the app genuinely needs.

How do I update Planetario?
Install the newer version on top of the old one — Android will keep your data. If the signature differs, uninstall first (you may lose local progress).

Why is the app not installing?
Common causes: not enough storage, an older Android version than 4.1+, or a conflicting build already installed. Free up space, check your OS version, and uninstall any previous copy before retrying.
