I came across the following sentence in Le Petit Prince:
Je savais bien qu'en dehors des grosses planètes comme la Terre, Jupiter, Mars, Vénus, auxquelles on a donné des noms, il y en a des centaines d'autres qui sont quelquefois si petites qu'on a beaucoup de mal à les apercevoir au télescope.
I tried to search the meaning of en dehors de... and I found out that it means outside of, apart from.
It's still unclear to me however, if it means:
- that they are outside of the known planets by means of distance (that they are much further away, they are distant, unreachable)?
- that apart from the known planets, there are also other objects (we just point out that some other objects exist, in addition to the objects that we already know about)?
Can someone explain this please?
