The Geminorum Cluster
Tagline for the system.
Some text about the system. Maybe break this into multiple sections with headers if you have a lot to say about the system. Or make another page and link to it here if you have a really, really huge amount to say. You can automatically make new pages by entering the text [ [ NewPageTitle ] ] (with the spaces removed). Clicking on the link that makes will let you edit the new page. That also works for linking to existing pages.
A star: Anything pertinent about the star. Maybe just the color; after all the color of the sun/sky is an important facet of a planet.
Some stuff about the notable planets. Again, if you have a lot to say, consider a sub-page
Actual planetary stats.
