Most are bereft. Life on such orbs may be beneath the surface. Also the size of each orb may dictate whether to visit another orb or not.

e.g. If we discover earth-like planets or moons that have 5 times our gravity, this is not good for us. The opposite may mean a visitor might have to dwell deep in our planet.

Also mode of transportation. Jut because we do it in flying tin cans does not mean they do.
