2. A few problems with this one.

First, Wolf 1061 is a red dwarf, type M3, which means it is a dim, cool star. Any planet in the habitable zone is going to be close in. And indeed, Wolf 1061c has an orbital period of about 67 days. This could mean that the planet may be tidally locked to its star, with one side perpetually facing the star as it orbits. I am not sure if this is the case, but it needs to be considered.

Second, this is a super-Earth, over five times Earth's mass. Now that does not mean five times the gravity, because gravity also depends on size. However, that's pretty damned massive for a terrestrial-type planet. It is likely that it is a rocky planet, but we just do not yet know.

Those are the kinds of questions I would be asking.

We need to know the planet's size/density, which will give us its gravity, and whether it could be tidally locked to its star.
