The planets are not to scale, ranging from roughly Earth-sized at the top of the image, to Jupiter-sized at the bottom. Planets labeled with questions marks represent those that cannot be characterized without further data.

Astronomers using a Maunakea observatory on Thursday published a “catalog” of more than 100 exoplanets.
