Freely travel among the stars and planets in this made for VR astronomy simulation. Experience space from some of the smallest solar system bodies to our largest planets. Or leave the solar system to explore strange new worlds orbiting stars so distant it takes light thousands of years to get here.

Early Access Game

Get instant access and start playing; get involved with this game as it develops.

Note: This Early Access game is not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“We want user input on features and operational mechanics as the game is built.”

Approximately how long will this game be in Early Access?

“Approximately 1 year.”

How is the full version planned to differ from the Early Access version?

“We expect the release version to be as bug free as possible and will have incorporated the best of the suggested features by our users. Of course the final version will have additional stars, exoplanets, minor planets, and spacecraft. In addition we plan to add 1:1 scale and provide a web interface to read about specific objects. Finally, the release version will move from the current version to Unity's HDRP.”

What is the current state of the Early Access version?

“Currently the game is stable and usable with thousands of stars and planets. Please see the "About This Game" section, all items mentioned are currently implemented.”

Will the game be priced differently during and after Early Access?

“After early access it may go up in price somewhat but It is intended to stay at a low price point.”

How are you planning on involving the Community in your development process?

“We would like comments and suggestions posted in the game discussions section.”

About This Game

Travel among the stars and planets In this made for VR astronomy simulation. Within the solar system you can visit all the planets and moons as well as many asteroids, trans-Neptunian objects, and other small solar system bodies. Outside the solar system, go to thousands of stars and their exoplanets. Also works on flat screen with keyboard and mouse.


All the solar system objects sizes and locations are based on accurate and up to date information. Where actual images are available you will see the correct texture or, if detailed information is available, a reasonable extrapolation is used. The orientation of the planets is correct relative to the solar system and the solar system itself is oriented correctly to the background stars.

Star color, brightness, size and position are taken directly from available data or are calculated. There are thousands of stars and exoplanets to explore. The habitability zone of each star is calculated and the exoplanets within it are textured appropriately for size, age, and rotation. As you explore you will see text for stars that are known to have planets as well as planets that are within the habitability zone.

Black holes have mass from the latest sources, size and event horizon assume a rotating black hole. Accretion disk rotation speed and doppler beaming effect are simulated along with the gravitation distortion of the background stars.

Objects move with time. Set a time scale and observe planets, moons, asteroids, etc. move in orbits determined by ephemeris data from JPL. See the motion of moons around Jupiter or the Earth around the moon, or the entire system around the sun. Time can move forward or backward and positions are extrapolated for time before or after the dataset.


Every object is labeled with an option to turn off the text. In addition, detailed information on each object can be displayed. When available, we collect data on position and orbits, size, mass, temperature, magnitude, luminosity, inclination, and more. You can do side by side comparisons with the sun, Jupiter, Earth, and the moon.

Currently there are:
  • 6096 Star Systems
  • 6720 Individual Stars, 16 black holes, 7 neutron stars
  • 8 Planets
  • 222 Moons
  • 91 Minor Planets
  • 5404 Exoplanets
  • 9 Spacecraft

There will be more.


You may freely move among all the stellar objects with only two controls. Left controller thumbpad/stick for movement, right to zoom. Separate scales for object size and distance allow you to see the entire solar system within arms length or you may zoom in to where size and distance scales are the same.


Terrible. It is possible to set a webcam (including from some headsets) as the background. Typically this is fuzzy and laggy. Your results may vary, but probably not.

Min Scale Distance: 1 meter = 2 light years.
Max Scale (both): 1 meter = 1,000 km
