The 100s of exoplanets discovered to date are an extremely diverse group. Many are Jupiter-like gas giants, but some have a rocky surface. Many are extremely hot, orbiting close to their home star, but some are icy-cold. Some orbit massive stars, many times more brilliant than our Sun, others circle dim red dwarfs.

And yet, even in such an eclectic group, some exoplanets stand out from the crowd. These are planets that possess some unique feature that singles them out. Or they are typical planets that are better studied and better known than the others. To provide a taste of what these alien worlds are like, here is a selection of a few such notable exoplanets and what scientists know of them.
