This isn't the right approach brother, I am sorry you have feelings for her, but its not the islamic way to get married. You should speak to the wali of a girl and avoid haram so you can marry rather than be in a long haram relationship.

There is no reason for it to be haram or wrong. It's just science, and personally I am fascinated by it.Many of the historical astronomers were Muslims and a lot of stars have Arabic names and are named by Muslim astronomers.
