<h3>Background</h3>
<p>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.</p>
<p>Similar to this:
<div class="youtube-embed"><div>
                <iframe width="640px" height="395px" src="https://www.youtube.com/embed/adJPV-sz5AI?start=58"></iframe>
            </div></div></p>
<p>I know the animation in the YouTube video was made with &quot;Stellarium Web&quot; 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.</p>
<h3>Question</h3>
<p>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.</p>

I think there are several posts here and in [Space Exploration SE](https://space.stackexchange.com/) 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?](https://astronomy.stackexchange.com/q/13488/7982).

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?

How are you experienced in programming? Do you understand the concept of OOP? JavaScript is a language, specially designed for browsers. Consider using some popular JavaScript 3d libraries, for example three.js, babylon.js, or WebGL.

I’m voting to close this question because This is not an astronomy question, but a programming one.

@User123 Well spotted, although we call that a cross-post, not a duplicate, since the usual processes regarding duplicates (like duplicate flagging & close-voting, and the system software that links duplicates) don't apply to questions on other sites.

Please do not cross-post. However, that question is far too broad for Stack Overflow, which is for answering questions about specific problems with your code.

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.

Astronomical resources helpful for creating an animation in the browser of the movements of an astronomical object in the sky?

# Astronomical resources helpful for creating an animation in the browser of the movements of an astronomical object in the sky?

(Asked by: username_0 on 2020-12-21)

### 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.
