That kind of planet might be?

that kind of planet might be? Be what?
Does it mean "that kind of planet might be capable of generating and supporting us"?

Context:

This distinction may seem puzzling, and I must explain it further,
using the so-called anthropic principle. The anthropic principle was
named by the British mathematician Brandon Carter in 1974 and
expanded by the physicists John Barrow and Frank Tipler in their
67
book on the subject. The anthropic argument is usually applied to
the cosmos, and I'll come to that. But I'll introduce the idea on a
smaller, planetary scale. We exist here on Earth. Therefore Earth
must be the kind of planet that is capable of generating and
supporting us, however unusual, even unique, that kind of planet
might be. For example, our kind of life cannot survive without
liquid water. Indeed, exobiologists searching for evidence of extra-
terrestrial life are scanning the heavens, in practice, for signs of
water. Around a typical star like our sun, there is a so-called
Goldilocks zone - not too hot and not too cold, but just right - for
planets with liquid water. A thin band of orbits lies between those
that are too far from the star, where water freezes, and too close,
where it boils.
