About this app

Stellarium Mobile - Star Map is a planetarium app that shows exactly what you see when you look up at the stars.

Identify stars, constellations, planets, comets, satellites (such as the ISS), and other deep sky objects in real time in the sky above you in just a few seconds, just by pointing the phone at the sky!

This astronomy application has an easy to use and minimalist user interface, that makes it one of the best astronomical applications for adults and children who want to explore the night sky.

Stellarium Mobile features:

★ View an accurate night sky simulation of stars and planets for any date, time and location.

★ Dive in a collection of many stars, nebulas, galaxies, star clusters and other deep sky objects.

★ Zoom on realistic Milky Way and Deep Sky Objects images.

★ Discover how people living in other regions of the planet see the stars by selecting the shapes and illustrations of the constellations for many sky cultures.

★ Track artificial satellites, including the International Space Station.

★ Simulate landscape and atmosphere with realistic sunrise, sunset and atmosphere refraction.

★ Discover 3D rendering of the major solar system planets and their satellites.

★ Observe the sky in night mode (red) to preserve your eyes adaptation to darkness.

Stellarium Mobile contains in-app purchases allowing to upgrade to Stellarium Plus. With this upgrade, the app will display objects as faint as magnitude 22 (versus magnitude 8 in the base version) and enable advanced observing features.

Stellarium Plus features (unlocked with in-app purchase):

★ Reach the limit of knowledge by diving in a massive collection of stars, nebulas, galaxies, star clusters and other deep sky objects:
  • All known stars: Gaia DR2 catalog of over 1.69 billion stars
  • All known planets, natural satellites and comets, and many other minor solar system objects (10k asteroids)
  • Most known deep sky objects: a combined catalog of over 2 million nebulas and galaxies

★ Zoom almost without limits on high resolution images of deep sky objects or planetary surfaces.

★ Observe in the field, even without internet connection, with a "reduced" set of data: 2 million stars, 2 million Deep Sky Objects, 10k asteroids.

★ Control your telescope through Bluetooth or WIFI: drive any GOTO telescope compatible with NexStar, SynScan or LX200 protocols.

★ Prepare your observing sessions using the advanced observation tools, to predict a celestial object observability and transit times.

Stellarium Mobile - Star Map is made by the original creator of Stellarium, the well known open source planetarium and one of the best astronomy applications on Desktop PC.

Ratings and reviews

It does show the C/2023 A3 (Tsuchinshan–ATLAS) comet currently passing by, but I can only find it using the search feature. Can't find by moving my phone around. If I search for it and turn on camera movement to figure out exactly where it is in real time, I completely lose track of it and it's impossible to find. The movement sensitivity is too high, I can see my heartbeat shaking the camera. Too much zoom out, turns into a dizzying fish eye lens thing.

very easy to navigate. been using this app for over a year. I love that it shows stars, comets, meteor showers, etc. pretty much anything you want to find in the sky. it has real time or can use slider to fast forward (good for tracking) my only con, which recently just started, is it keeps saying to calibrate my location and location not being accurate. I've done what it says to do many times with no luck. other than that and even with that, this is still a great FREE app.

Wonderful aid for stargazing! A real game-changer. Transient objects like comets seem hit-or-miss. Sometimes they show up, then they don't, then they do again. Maybe it has to do with cell service coverage? If so, then offline use could be made more robust. Lots of observing happening in remote/rural locations.

What's new

This update brings the following improvements:

- improved the 3D model for Rhea
- simulate planet sphere flattening
- Mars satellites position is now very accurate
- add a Milky Way searchable object
- many other bug fixes and translations improvements
