Can someone update the hypothetical pic from this article please. I don't know enough about public domain images to do it myself. Sandman1142 (talk) 20:30, 14 October 2024 (UTC)

That's just an artist's impression, there are already some in the article. SevenSpheres (talk) 20:40, 14 October 2024 (UTC)

Says who? 2A02:3100:B24D:FE00:84B0:8393:D7E8:F906 (talk) 01:18, 19 February 2025 (UTC)

Because we know its size* and its mass, so should we add density? Fred1000000000 (talk) 05:56, 26 May 2025 (UTC)

I have also calculated the density witch is 7.1072138165419 g/cm Fred1000000000 (talk) 06:23, 26 May 2025 (UTC)
(if it’s mass is 1.07 earth masses and  0.94 earth radius) Fred1000000000 (talk) 07:12, 26 May 2025 (UTC)
We don't know its size; the values given are based on assumed compositions. 21 Andromedae (talk) 18:11, 26 May 2025 (UTC)
No, that would be highly misleading. There is no radius measurement so the density is unknown. The article lists a range of plausible radii. SevenSpheres (talk) 16:40, 26 May 2025 (UTC)
