Description

Warp to distant stars and explore various exoplanets like lava worlds, water worlds, earthlike planets or massive jovians with Stars and Planets planetarium app and astronomy guide. Space is awesome and the universe is at your fingertips!
Take a thrilling ride through space and visit strange new alien star systems such as multiple star systems (from binary to septenary), multiple planetary systems, circumbinary planets and disks, black holes, pulsars, magnetars and the moons of our solar system.
Ever wondered how far from Earth are the stars you see in the night sky? Or how far or close they are to each other? Now you can visualize those distances in 3D with a star map divided into 10 parsec sectors (cubes) or 32.62 light years, for an easier observation.

Features
▶ Almost 4.5 million stars, over 4400 exoplanets, 200 circumstellar disks, 38 black holes, 11 magnetars, around 2500 pulsars and 152 moons in the database
▶ Exoplanets are updated daily from multiple sources, without needing to update the app. Some exoplanets' appearance will change in time, they may be classified as possible earthlike planets in the beginning, but recent studies will show that they are more like a Venus type world.
▶ Stars extracted from SIMBAD from multiple catalogs like the European Space Agency's Hipparcos mission, the Gliese catalogue, parts of the ASCC - All Sky Compiled Catalogue and the most recent GAIA catalogue
▶ 3D representations of all star systems and their orbits (green stars = unknown spectrum)
▶ black holes in binary systems, including the famous Cygnus X-1 and the Great Annihilator (the only binary system with a black hole and a pulsar)
▶ pulsars and pulsar planets - the first type of planet ever discovered beyond our solar system, orbiting the extremely dense core of a massive star that exploded as a supernova. Fewer than 1% of pulsars have been found to host planets.
▶ magnetars, a special and rare type of neutron star
▶ Search for stars, planets, disks, black holes, neutron stars and magnetars by a wide range of parameters: name, type, system type, constellation, catalog, star type (color)
▶ Detailed information for every stellar object

Explore space and get a little closer to our wonderful universe with this awesome astronomy app!
This interactive 3D map is excellent for teachers to use for instruction, and it is a great resource for students to explore the Milky Way galaxy and space as they learn more about the universe we live in.

An internet connection is necessary to access the online stellar database as well as the wiki information. A subset of the database between sectors (-10,-10,-10) and (10,10,10) can be queried offline including planetary and orbit data.

Data imported from various sources including:
SIMBAD - http://simbad.u-strasbg.fr/simbad/sim-fbasic
The Extrasolar Planets Encyclopedia - http://exoplanet.eu/
NASA Exoplanet Archive - https://exoplanetarchive.ipac.caltech.edu/
Planet Habitability Laboratory - http://phl.upr.edu/projects/habitable-exoplanets-catalog

Close up look at distant stars

One caveat: the app only lets you view a 10-parsec cube at a time; no giant overview to give a clear idea of how far from the sun the area you're looking at is.
However, this is only the second 3D map I've found of our corner of the galaxy that's not stuck centered on the sun! If you'd like a closer view of the area around a particular star, from any angle (what do the Pleiades look like from the back?), this is excellent. Selecting any star gives some basic information: other names, type, magnitude, temperature, a diagram comparing its size to the sun, and a map showing its position in the night sky. There's also a Wikipedia link, though some star pages don't exist yet. Ads generally stay out of the way at the top of the screen, though sometimes they get in way of the back button on star pages (just rotate your phone). Search function hasn't failed to find the stars I'm interested in, but I don't know enough to look for anything really obscure, so I don't know how thorough it is. Very pleased with the app overall!

Thanks for the great review!
I've split the map into 10-parsec cubes so that it works on older models with no significant lag. It is possible to view more than that, I was thinking of adding a "zoom out" feature that shows the adjacent sectors, so instead of viewing a 10 parsec cubes, you will be viewing 30 parsec cubes. I will have to test how much more can be zoomed.

But my first major update to this app will be a highlights section with a list of famous stars, weird stars, multiple star systems.

Explore the Stellar Neighborhood

I’ve greatly enjoyed using this app to traipse across the local area of the galaxy and see where stars are near each other in 3D space. The ads in the free version are unobtrusive and I’m considering upgrading to the full version just because I like enjoy it so much, even though the free version fulfills my needs without issue. The 10-parsec sectors would be perfect for making a map in a sci-fi roleplaying game.

One feature I would like to see, however, is a setting to change from xyz equatorial coordinates to uvw galactic coordinates so I could know whether I was getting closer to the galactic core or farther away, above or below the galactic plane, or in the direction of spin without having to do calculations in my head. Maybe an option to rotate the +Z into the vertical position instead of the +Y too, since I instinctively associate the North star with “up” when working in equatorial coordinates.

I hope you like this new version, I've completely redesigned the app, and new planets are added daily without needing an update (if new ones have been confirmed). Thanks for the review!

Broken

I really liked this app, but the last 2 updates have completely broken it. The background has changed to white instead of black, I can’t see the stars anymore. It’s effectively unusable. Really hoping it gets fixed soon

EDIT 1/3/22: The white background has been fixed, and this app is now back and better than ever! So glad to see it working again - 5 stars! This is the best 3D star map program I’ve been able to find anywhere, which is why I was so bummed out when it turned into a blank white screen. It looks great again now!

Developer Response ,

Should be fixed now in 2.4.14, sorry!
