Background

I would like to create a website that shows an animation of the path of Sagittarius A* (or any other object in space) during one day for a specific location. So that the user can see where and when Sagittarius A* is rising, what path across the sky it takes and where and when it is setting.

Similar to this:

I know the animation in the YouTube video was made with "Stellarium Web" and I could make something like that with Stellarium for Sagittarius A*. But I would like to have it interactive on a website where the user only has to enter his current location and then would see the animation of the path for his location.

Question

Where can I find astronomical resources for getting the data necessary to make such a plot in a way useful for a website? It would have to be something I could call from, or incorporate into a website, not a stand-alone program.

  • $\begingroup$ I think there are several posts here and in Space Exploration SE that will be helpful, and it might be worth searching yourself to see if anything suits your needs. There is one page of resources here Where can I find the positions of the planets, stars, moons, artificial satellites, etc. and visualize them?. $\endgroup$ – uhoh Dec 21 '20 at 5:53
  • $\begingroup$ Making a website simulate spots on a blank screen is one thing, adding a horizon and foreground objects is another; it's a big project, so any more details you can add will be great. For example, what computer and website programming languages are you willing to use and/or learn? $\endgroup$ – uhoh Dec 21 '20 at 5:53

    $\begingroup$ I’m voting to close this question because This is not an astronomy question, but a programming one. $\endgroup$ – StephenG Dec 21 '20 at 8:38

    $\begingroup$ Plotting the movement of astronomical bodies in the sky is on-topic. We can simply constrain the question a little bit rather than insta-close it. voting to keep open and making a helpful edit. $\endgroup$ – uhoh Dec 21 '20 at 12:46
