Welcome to the

Exoplanet Catalogue

This is an experimental project for rendering the orbital mechanics of star systems known to host one or more exoplanets in the browser. It is a kind of orrery. The data is derived from the Open Exoplanet Catalogue. Special thanks to all contributors.

Please note that this project is still under development and not all star systems currently render accurately or even at all. The math is complex, and there are many unresolved variables and formulae, but there is an exciting roadmap and the work goes on.

Also note that distances are not to scale. Space is big. Really big. Distances have been compressed to facilitate easy viewing. I plan to make the distance ratio dynamic in future to interactively show how utterly, mind-bogglingly big the distances are.

So, while there is still much to do, I hope you have fun exploring other worlds in the Milky Way.

If you like what you see, feel free to share and shout out on Twitter or email me.

All the best,

Ian
