Say what is written about a world, when asked

Every figure this map shows is a measurement or something derived from one,
and it says which. What it could not do was tell you what a place is — a
radius and an eccentricity do not say that Titan is the only moon with a dense
atmosphere. An About control on a body's panel now fetches the Wikipedia lead,
and it is labelled as what it is: prose from another site, credited and linked
back, below the line where this map's own figures end.

Only on the press. Nothing is fetched while a body loads, and nothing is
fetched twice.

Three things the encyclopedia does that had to be handled, all found by asking
it rather than by guessing:

It redirects, generously — "Proxima Cen b" lands on "Proxima Centauri b" and
"Kepler-22 b" on "Kepler-22b" — so the catalogue's own names can be sent as
they are, with no mapping table to maintain.

It disambiguates. "Titan" is a list of everything called Titan, and so are
"Mercury" and "Io". Wikipedia says so in the response, and this app happens to
know the kind, so a disambiguation is retried as "Titan (moon)". Only in
English: every wiki words its own qualifiers, and inventing a translation of
one would be inventing an article title.

And it rate-limits, which it did to me while I was checking the above. A
refusal to answer is not an empty answer, so the two are separate outcomes:
"Wikipedia has no article on this" is about the world, "Wikipedia could not be
reached" is about this minute — and only the first is remembered, so a second
press is allowed to try again.

The extract is capped and scrollable. A lead can run a dozen lines, and this
panel is anchored to the top of a viewport that may be shorter than the prose.

Verified: build clean, 606/606 unit including twelve for the lookup chain, 16/16
end-to-end including three that stub the encyclopedia — this suite tests the
panel, not Wikipedia — design detector clean, and the real thing exercised by
hand against Earth, Titan and Proxima Cen b at three viewport sizes.
