CLUSTER DESKTOP-NIGHT-PLANETARIUM · 23 ENTRIES · EARLIEST ENTRY 2011-03-04
Astronomy sky charting apps
This cluster spans planetarium, stargazing, and observation-planning tools that render or identify the night sky, covering desktop, terminal, mobile, and AR form factors. Its dated history is thin—only 10 entries before the index start, scattered from 2011-03 to 2026-06 with no clear trend—so its shape cannot be reliably read. Traction leaders are KStars, Smart Radio Telescope, and Sky Map, each with 0 stars.
Entry timeline
ENTRY TIMELINE
Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.

Two labels per entry, never collapsed into one: how it was built, and who stands behind it. Counted over the 3 listed below. Unlabelled means nothing has decided yet — not that the answer is small.

Ranked by traction, highest first, and paged 20 at a time — this is a window on the cluster, never the whole of it. Ties are broken by a stable id so a product cannot appear on two pages or fall between them. Browse every cluster.
