([en.wikipedia.org](https://en.wikipedia.org/wiki/Proxima_Centauri?utm_source=openai))\n\nHere are a few extra details:\n\n- Proxima Centauri is part of the Alpha Centauri star system (specifically, it's often called Alpha Centauri C), which also includes the two brighter stars Alpha Centauri A and B. ([en.wikipedia.org](https://en.wikipedia.org/wiki/Proxima_Centauri?utm_source=openai))  \n- Despite being relatively close in cosmic terms, Proxima Centauri is a small red dwarf star, much dimmer than our Sun. ([science.nasa.gov](https://science.nasa.gov/asset/hubble/proxima-centauri/?utm_source=openai))  \n\nIf you meant \u201cclosest\u201d including non-star objects like brown dwarfs, or under different definitions, I can clarify further!"
