How much does it cost to buy a star Constellation?

Excuse me, I'm interested in purchasing a star from the Constellation program. Could you please elaborate on the pricing structure involved? Is there a fixed cost for each star, or does the price vary depending on factors such as its brightness, location, or any other characteristics? Additionally, are there any hidden fees or ongoing costs associated with owning a star through the Constellation program? I'd appreciate any clarity you can provide on the financial aspects of this unique investment opportunity.
