The planet has breathable air, ice and vegetation;
atmosphere, hydrosphere and biosphere would not survive the expansion of the sun "'...without artificial help...'"; (p. 402)
therefore, the planet is inhabited.
Donovan, who has been here before, adds that:
the star is near the center of the Black Nebula;
it is in a hollow space where there is not enough dust to retard the planet and make it spiral inward to collide with the star;
further, the star has the same velocity as the Nebula and therefore stays in the hollow space.
Questions:
How can there be a hollow space in a dust cloud?
Do the Nebulites/Arzunians keep the space clear of dust psychokinetically?

I'm not sure the bit about the "hollow space" and dust makes sense scientifically. It might have been something astronomers of the early 1950's speculated about for a while and then discarded. That is what it seems to "feel" like to me, anyhow.

I’m behind on the blog, you may note. Radiation pressure from the star might maintain a hollow in the nebula; I’m just saying might, since I am not an actual astrophysicist, although I wanted to be one as a child, and we are not told enough about the composition and density of the cloud, the output of the star, etc.

Kaor, Nicholas!
And I hope we do see more comments by you!
