A pleasure. Comments soon. --Jens Lallensack (talk) 12:30, 3 March 2019 (UTC)

• I would expand the lead a bit, as it is supposed to provide a summary of the article. For example, you could add the position of the orbit (between Kerberos and Styx), and maybe something about the name.
• Before the discovery of Nix and Hydra – it was not previously mentioned in the main text that they were discovered at the same time. The main text should be independent of the lead.
• In particular, the names of features on Nix must be related to deities of the night from literature, mythology, and history.[16] – Maybe worth adding if such features on Nix have been named already?
• However, the collisional hypothesis cannot explain the presence water ice is on the surface of Nix. – I don't understand. Is there water ice (if so, it should have been stated before).
• Why are "physical characteristics" within the heading "Origin"?
• The neutral spectrum of Nix signifies a water ice composition on its surface – unclear: Does this mean the surface consists mostly of water ice?
• Nix also appeared to vary in brightness and albedo, or reflectivity. – Imprecise: Do different parts of the surface have a different Albedo, or does it change with time? And how is this variation explained?
• The reddish area is thought to be a large impact crater where dark material was ejected from underneath Nix's water ice layer – why "dark"? I thought the crater was red, or does that mean the same here?
• In this case, Nix would likely have a layer of regoliths on its surface. – That would mean it had regoliths within the water ice layer?
• though there were no significant color variations on other impact craters on Nix.[21] – why switching to past tense here?
• Water ice is present on the surface of Nix – as the water ice is already mentioned, I suggest "The water ice present on the surface of Nix …"
• similarly to the small moons of Pluto – to the other small moons? Nix is also one?
• The rotation period of Nix had increased by 10 percent – "increased" here means a longer period, which would mean it now rotates more slowly?
• Last paragraph of "Physical characteristics" appears to belong into "Orbit".
• faster than the effects of tidal interactions with Pluto itself – and why? Why Charon, and not Pluto, or both?
• with a timing discrepancy is 2.8% – "of 2.8%"?
• Of Pluto's smaller moons, only Nix and Hydra were imaged at resolutions high enough for surface features to be visible. – needs source.
• with resolutions as high as 330 meters per pixel – this info from the lead is missing in the body. Needs a source, and also a conversion to feet. --Jens Lallensack (talk) 13:10, 3 March 2019 (UTC)

Thank you for the feedback, I've used these to make further edits to the the article. I'm not sure if Nix's rotation is more based on its orbit or physical characteristics, so I've made a subheading separating the text about its rotation from the main text of its physical characteristics.Nrco0e (talk) 00:46, 4 March 2019 (UTC)

OK, all fine then! Congrats, and thanks for the article. --Jens Lallensack (talk) 15:04, 4 March 2019 (UTC)
