The expandable free and open-source real-time space simulator that lets you explore our universe in three dimensions.
I think Celestia could be a good one. I also thought about SpaceEngine, but AFAIK it was kind of terrible at generating realistic planetary systems, among other things (pricey, huge, etc.). Source: about 1 year ago
Celestia was something I played with before. Pretty interesting. Source: over 1 year ago
Celestia looks as though it would do it. Source: over 1 year ago
I'm looking for data and software to visualize the Apollo 17 trajectory (especially the "powered descent", lunar rendezvous and entry). I'm thinking of using celestia. I'm look for a data tables as well (time stamp, position for each part of the stack). Any tips are appreciated. Source: over 1 year ago
Yes, that's Celestia most likely. I'm not sure it is still maintained though. Source: over 1 year ago
I hope this information has been useful to you, and enlightening. See the free PC programs Stellarium and Celestia if you'd like to learn more about the movement of the Earth and planets, as well as other objects in the night sky. Source: over 1 year ago
Great news, thanks to all the maintainers! I wish someone with the right expertise could modernize Celestia[1] like that. [1] https://celestia.space. - Source: Hacker News / over 1 year ago
If you wish to demonstrate this to yourself, grab Celestia, a free celestial exploration program that you can easily use to show the lack of change in star positions across seasons, but then move a substantial distance away in order to show the motion of stars over large distances. Here's an example. Source: over 1 year ago
What? You mean like Celestia or Sky Map? That's not really cosmology you know. Source: over 1 year ago
I haven't used it, but the free program Celestia is supposed to be able to do this. Source: almost 2 years ago
I think you can do this with either Celestia or Stellarium but they've been updated since I used them years ago. I know you go forward and backwards in time, but not sure 3,000 years is possible, but maybe. Here's another list of possibilities I found though. I think screen captures are possible with the first two. Source: almost 2 years ago
There are multiple. I like using SkySafari. Celestia is FOSS software that will also do this. Source: almost 2 years ago
If you like this, definitely check out Celestia, it's amazing. The download/install is super quick and you have a full program containing all known stars (I think). To feel proper awe, make sure to crank up "visible stars" with ] and then start zooming out. Source: almost 2 years ago
If I may suggest Stellarium: https://stellarium.org/ A dark room with a projector would be nice, but a computer monitor also works. It's also good for letting you have an idea of what you can see & when. You can also try https://celestia.space/. Source: about 2 years ago
Very neat! This is similar in concept to the Celestia: https://celestia.space/ Celestia has been around for years so the spaceinbrowser site can't really compare in terms of features. But being able to run in a browser rather than having to download and install a desktop application makes it so much more accessible. The effort put into performance optimization shows. I'd love to see more planets added. - Source: Hacker News / about 2 years ago
If you want a 3D representation of the Galaxy with procedurally generated stars, you'd be better off just downloading the Space Engine or Celestia. Source: about 2 years ago
You could also just talk about the topic. Explain, in an age-appropriate manner, what stars, planets and moons are, how they behave in space, what they are like, show pictures and videos of them, use a program like Celestia or SpaceEngine to explore the galaxy a little, play some Kerbal Space Program with him, perhaps have him run around you like a moon would orbit a planet.

Celestia: https://celestia.space/ Stellarium's cool too, but it's more focused on what you see if you look up at the sky. Celestia's more of a broad "fly around the known universe"-type of simulator. - Source: Hacker News / over 2 years ago
You can use this program to view the stars from different positions in the galaxy if that helps. Source: over 2 years ago
