![]() ![]() If done correctly, Stellarium will show the spherical Earth in all its glory, as seen from the Moon. Zoom on to the selected object (Earth): /. ![]() Turn off horizon if the Earth is below the horizon: G.Find the Earth: Ctrl-F, type “earth”, Enter.Move observer to the selected object (Moon): Ctrl-G.Find the Moon: Ctrl-F, type “moon”, Enter.However, we can easily prove this wrong by using Stellarium to simulate how the Earth appears from the surface of the Moon: Some flat-Earthers claim that Stellarium is made using the flat Earth model. We can use the app to tell us if it is just an error in the model or an actual discrepancy between observation and expectation. ![]() If the result produced by Stellarium matches the actual observation, then there is nothing wrong with the spherical Earth model. Stellarium includes vivid illustrations of the constellations and a theatrical display of ravishing nebulae and galaxies. You can view the planets and gaze at the stars in stunning detail. It shows a realistic sky in 3D, just like what you see with the naked eye, binoculars, or a telescope. Stellarium uses the spherical Earth model. Stellarium Portable is a free, open source planetarium for your computer. ![]() In addition, there is a version for mobile phones/tablets, albeit a paid one, and a simpler web-based version. It is freely available for all the major desktop operating systems. Stellarium is free software and costs nothing to download. It can render a realistic projection of the sky in real-time and any time in the past or the future, with relatively good accuracy. And the problem was just caused by their failure to understand and to create the correct model. If it produces the same result as the actual observation, then they have nothing to complain about. We can ask them the time of the event and the observer’s location, then use Stellarium or a similar app to simulate the event. They would incorrectly proclaim it as “evidence” of a flat, stationary Earth. Time: 2020 September 6, 21:00 (UTC -05:00)Flat-Earthers like to mention an astronomical event or a specific celestial geometry and insist it cannot possibly occur if Earth is a rotating sphere orbiting the sun.
