Sure, here is a simple HTML game that meets your requirements. It may not have all the advanced features you mentioned, but it should give you a basic idea of how the game works:
To play the game, simply open the above HTML code in a web browser. The game starts with an initial planet at the center of the canvas. You can create more planets by tapping on the screen at different positions. Planets will grow in size if they collide with a star's habitable ring. After 1 minute, a red giant star will appear, collapsing all other stars on the canvas.
