Stellarium PLUS

Stellarium Mobile is an astronomy app that precisely shows you everything you would see when looking up at the night sky.
Just point your phone at the sky and instantly identify the stars, constellations, planets, comets, satellites (such as the International Space Station), and other deep-sky objects in the sky above your head within seconds!
This astronomy app is easy to use and has a simple user interface, making it one of the best astronomy apps for both adults and children who want to explore the night sky.
Features of Stellarium Mobile:
• Watch precise night sky simulations of stars and planets at any date, time, and location.
• Gain in-depth knowledge of a vast collection of diverse stars, nebulae, galaxies, star clusters, and other deep-sky objects.
• Zoom in on realistic images of the "Milky Way" and "deep-sky objects".
• Select the shapes and diagrams of constellations in many celestial cultures and explore what the stars look like as seen by people living in other parts of the world.
• Track artificial satellites including the International Space Station.
• Simulate landscapes and the atmosphere with realistic sunrises, sunsets, and atmospheric refraction.
• Explore 3D renditions of the major planets in the solar system and their moons.
• Observe the sky in night mode (red) to keep your eyes adapted to the dark.
The free mobile version of Stellarium Mobile includes in-app purchases to upgrade to the enhanced Stellarium Plus mobile version. After upgrading, the app will display dimmer objects up to magnitude 22 (compared to magnitude 8 in the basic version) and enable advanced observing features.
Features of Stellarium Plus enhanced mobile version (unlockable via in-app purchases):
• Gain in-depth knowledge of a vast collection of stars, nebulae, galaxies, star clusters, and other deep-sky objects, pushing the limits of knowledge:
  - All known stars: Gaia DR2 catalog, over 1.69 billion stars
  - All known planets, natural satellites, and comets, as well as many other small solar system bodies (10,000 asteroids)
  - The most famous deep-sky objects: a combined catalog of over 2 million nebulae and galaxies
• Zoom in on high-resolution images of deep-sky objects and planetary surfaces with almost no restrictions.
• Use the "compact" dataset to observe in the field (even in places without internet connectivity): 2 million stars, 2 million deep-sky objects, 10,000 asteroids.
• Control your telescope via WIFI: drive any GOTO telescope compatible with the NexStar, SynScan, or LX200 protocols.
• Use advanced observing tools to prepare for observing sessions and predict the observability and transit times of celestial objects.
Stellarium Mobile is created by the original team behind Stellarium, a well-known open-source planetarium and one of the best astronomy apps on desktop computers.
