Terrestrial world but no pop

[runawaypally (OP)]

I have been running into terrestrial worlds with Venusian atmo that have a (-) population column. Some of these worlds are around Earth in size, others Jupiter. Is there a way to get a population stat on these bodies, or are they permanently uninhabitable?

Some venusian worlds just have a CC too high to put any pop there. Maybe that's what you're seeing? Where do you see that column exactly? Screenshot?

This is the super massive one, deleted the other game with the two smaller earth sized ones.

The gravity is too high. You can not place a population of a species on a world which exceeds its maximum gravity tolerance (for default humans this is 1.9 G).

That was it, I used SM mode to shrink it, and the pop column populated. Thanks for helping with the answer.

There is a research line for genetic modification of your race, to increase the ability of your populations to adapt to extreme conditions: very cold or hot, high and low gravity, and high and low oxygen leves. And a dedicated building to convert the pop.
I never used it, so I don't know details for its application. But maybe some AAR described it.
