Solar System in your Phone
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

Open the downloaded APK file from your Downloads folder
Tap "Install" and wait for installation to complete
Launch the app from your home screen
Make sure to re-enable Unknown Sources restrictions after installation for security.
How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be com.jacquesb.planetario_a is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 2.0 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall Planetario first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of Planetario, and a listing is removed when the evidence for it stops holding up.

The signing certificate fingerprint for this release is on record, so a build that does not match it did not come from this publisher.
