Just the one is extremely impressive IMO.  The angualar separation is tiny.

The Gemini Planet Imager Exoplanet Survey has, halfway through its total sample of 600 stars, detected a total of six planets (and three brown dwarfs), although most of these had been previously identified in earlier, smaller studies (https://ui.adsabs.harvard.edu/abs/2019AJ....158...13N/abstract).

Can you say where you saw that the GPI would *discover* tens of new planets (as opposed to directly imaging tens of planets, which is obviously something different)?

@ProfRob It was years ago. I may have misremembered.

Why did Gemini Planet Imager hardly detect anything?

GPI was originally thought able to directly image tens of planets but [so far has only discovered one new planet](https://en.wikipedia.org/wiki/Gemini_Planet_Imager#Achievements)?

Why is this?
