Is the albedo of any of the Trappist-1 planets know? Is it high enough so if you are on the surface of one of the planets, you can see the others?

I looked up the distances from the star and size of the planets and it seems a few of them will appear larger than the Moon in the night sky, unless the albedo is really low that is.

  • $\begingroup$ I think that the consensus is that they are all close enough together and large enough in size that you'd be able to see them regardless of their albedos. $\endgroup$ – Phiteros Feb 25 '17 at 3:31
