Untitled[edit]

Probably best if we restrict this list to bodies to "worlds" in hydrostatic equilibrium or (like Vesta) nearly so. Otherwise it wouldn't be interesting. — kwami (talk) 03:43, 18 October 2011 (UTC)[reply]

Where is the lunar crater Korolev?[edit]

The Korolev Crater on the far side has a diameter of 437 km. I don't understand why it's not in this list and it makes me wonder what else is missing. DrZygote214 (talk) 00:52, 5 July 2015 (UTC)[reply]

larger crater on Pluto[edit]

for anyone who was curious of my claims of a larger crater on Pluto, the latest NH images (released Nov 12 "psychedelic Pluto") show an arc slightly above and to the right of Sputnik Planum. It's difficult to tell its exact size, and it's clearly quite old. Either way, it seems to be the largest confirmed crater on Pluto. exoplanetaryscience (talk) 04:15, 18 November 2015 (UTC)[reply]

Naming convention[edit]

Isn't the Earth's moon called Luna, not "Moon"? Perhaps Terra is also a better name than "Earth". Ignesandros (talk) 04:38 AM, 23 February 2017 (UTC)

Ganymede crater[edit]

The source given for the "unnamed crater" on Ganymede [1] lists its radius as 7,800 km; its diameter would be 15,600 km, the figure given in this article. Either way, that would make the crater's diameter 3x larger than Ganymede's diameter (at 5,270 km), which is geographically impossible. Other articles on the crater give the same 7,800 km figure, and are probably quoting the above article.--Father Goose (talk) 21:47, 16 May 2021 (UTC)[reply]

Hellas[edit]

What does Largest visible crater in the Solar System mean? Are there known invisible craters? —Tamfang (talk) 22:53, 24 May 2023 (UTC)[reply]

I was wondering that too, maybe it means largest fully visible/non-obstructed crater in the Solar System? If that's what it's meant to mean, I don't know why they wouldn't just write non-obstructed. Sealpaii (talk) 03:57, 4 January 2024 (UTC)[reply]

Why is Ceres listed with (asteroid)?[edit]

I thought Ceres was definitely a dwarf planet, writing asteroid while also having objects like Vesta listed is kinda confusing is it not? Sealpaii (talk) 03:56, 4 January 2024 (UTC)[reply]

According to Asteroid, Ceres is both a dwarf planet and an asteroid. I have changed it on this table to be "dwarf planet" along with Pluto, for specificity. -- Beland (talk) 19:04, 6 July 2024 (UTC)[reply]

Weird ratio math[edit]

Calculating the ratio of crater diameter as measured on the surface of a body, to the body diameter as measured through the center of the body, is weird, because the former can be 628% of the latter (2 pi). The linked articles seem to instead use the surface area percentage of the body affected by the crater, which seems more intuitive. I think the ratio column in this table should be replaced with those numbers. -- Beland (talk) 19:06, 6 July 2024 (UTC)[reply]

I support doing this, especially since impact basins are often non-circular above the 500 to 1,000 km mark. ArkHyena (talk) 20:57, 6 July 2024 (UTC)[reply]
