What “stellarium” means

Wikipedia

A stellarium is a three-dimensional map of the stars, typically centered on Earth. They are common fixtures at planetariums, where they illustrate the local deep space. Older examples were normally built using small colored balls or lights on support rods, but later examples used a variety of projection techniques instead.

#stellarium across platforms

every network with a public tag surface

Follow #stellarium straight to each platform’s own tag page. Where a platform publishes open data we measure it above; the rest lock their numbers behind paid APIs, so we link rather than guess.

Every number above is measured from a named public API at the shown fetch time. Nothing is estimated or extrapolated. Platforms that lock their data behind paid APIs are not shown. Agents: the same numbers, as JSON, at /api/hashtags/stellarium
