I want to know a bit more about this planet before we contact them.

The others escape, but the group's leader, Kley, now knows that the group was not told everything they need to know about this planet.

Little is known about this mysterious and dark planet.

"Has he told you anything new that we didn't know about this planet?"

Once here we can't go back to space because no one must know about this planet.

We don't know too much about this planet we have reached.

Other than the few ruins like these, little is known about this planet.

We know nothing about this planet except that it's dangerous.

They know too much about this planet and us humans.

Tell me what else I'll need to know about this planet.
