How to start coding a real time Constellation Viewer

Hello Comunity!
I am really new in coding and how to use Unity but I got interested in apps like Star Chart or Skywalk, so I need some help. Basically, How should I start to create the scene like the constellation viewer and how to put all the data I have of the star like a csv data?

Hoping some answers and thanks!

You may use Unity - Scripting API: Gyroscope to calculate device orientation and Unity - Scripting API: ParticleSystem to display stars. You can draw constellations with Unity - Manual: Line Renderer component and use TextMesh Pro User Guide | TextMesh Pro | 1.3.0 to print their names. Also you’ll need this for background Unity - Scripting API: WebCamTexture

Probably you should get started from the beginning
