Planet
Read full descriptionHide full description
This App gives details about temperatures in our solar system. Beside the theoretical temperature the app will show actual facts about each planet like the albedo, temperature, average distance to sun and details about the atmosphere. It is specially programmed to help understanding the climates in our solar system and is helpfull for students, schools and teaching.

This solar system simulator reflects actual planetary position information. When the app is launched, the sun is positioned 20 cm in front of the device, based on the device's position. Around it, the eight main planets of the solar system and the celestial body to be observed orbit. The orbits are displayed as if they were trajectories. The position of each planet is calculated based on actual values. # Features - x] Realistic solar system with ARKit - x] Orbits of the 8 planets are displayed. - x] Planets are realistic textures imported from USDZ files. - x] Planet positions are calculated based on real values (using Horizons API) - x] The object to be observed can be changed. - x] Display of the orbit of the object of interest - x] Calculate the position of the target object based on actual values (using the Horizons API). - x] Adjustable speed (minus value for reverse rotation) - x] Zoom function (zoom in/zoom out) - x] Toggle the display of the text information and the coordinate axis (New!) ## How to use 1. when you launch the application, you will be asked for "permission to use camera" at the first startup. If you allow it, an ARKit session will start. 2. 2. a coordinate axis will be placed 20 cm in front of you, based on the device's position. 3. Tap the "Load Planet" button to load the planet model. Just wait a moment. 4. The 8 main planets of the solar system and the object to be observed will orbit around it. 5. Move the device to observe the solar system from various angles. 6. Tap the buttons at the bottom of the screen to adjust the speed and zoom. 7. You can change the object to be observed from the menu in the upper right corner of the screen. 1. Halley's Comet 2. Hayabusa2 & Ryugyu 3. Voyager 1 & 2 4. New Horizons & Pluto 5. Cassini (New!) 6. OSIRIS-REx & Bennu 7. Comparison of Circle and Ellipse 8. Geocentric theory (New!) 8. Toggle the display of the text information and the coordinate axis from the menu in the upper right corner of the screen. (New!)

Verdict
The clearest difference is iOS requirement: Planet at 15.4 against Real Solar System's 17.6. On price, update cadence, ads and in-app purchases there is nothing between them.
