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. SIMULATION 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. DATA 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. VR EXPERIENCE 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. AR EXPERIENCE 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.Currently:Min Scale Distance: 1 meter = 2 light years.Max Scale (both): 1 meter = 1, 000 km
