Amaral (crater)
crater on Mercury
Amaral is a crater on the planet Mercury. With its smooth floor, surrounding ejecta, and small secondary craters, it appears noticeably younger than the heavily cratered surface around it. Along with a smooth crater floor, Amaral also has a central peak. Bright material on this peak is of particular interest as it appears to have an unusual color. In color-enhanced images, the central peak of Amaral appears as a bright blue color in striking contrast to the otherwise orange tones of surface material nearby. The different color of the central peak likely indicates rocks with different chemical composition from those on the neighboring surface.
Amaral is the second-largest crater of the Kuiperian system on Mercury, at 105 km (65 mi) diameter, after Bartók at 118 km (73 mi). It is followed by Tyagaraja crater.
A confirmed dark spot is present in southeastern Amaral.
The crater Heaney is to the southeast of Amaral.
Begin with the source’s own compact description: “Amaral (crater)” is crater on Mercury. The dossier treats that line as a proposition to test through Amaral, crater and Mercury, not as a finished interpretation.
Why this record matters
The phrase “crater on Mercury” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 20, 2026. The linked authority identifier is Q2782102. Authority coordinates are -26.400, -242.300. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
