The star HD 209458 has an extrasolar planet orbiting it.
The Observational astronomy learning project has activities for participants that guide them through the same process that an astronomer uses to analyze data. Participants in the Extrasolar planet project explore telescope data to find planets orbiting distant stars. The goal is to create a learning group where participants can compare notes and document the search process and to create an extended learning activity about exoplanets. No prior experience is needed; participants get step by step instructions on how to get started.
