Hubble's top 10 nearest neighbors span five distinct subcategories — Research Organizations, Government, Actors, TV Personalities, and Technology — with no single kind dominating the set, a signature of a broad audience shape.

The two strongest pulls are fellow Research Organizations: International Space Station at 0.80 and ISS Research at 0.75. Three Government-subcategory NASA properties follow closely — NASA Astronauts (0.75), NASA's Johnson Space Center (0.71), and NASA (0.69) — forming a coherent space-agency cluster across the top five. NASA's Kennedy Space Center (0.68) extends that cluster to six of the top ten. The remaining four positions break from the space-organization pattern entirely: Mark Hamill (0.67, Actor) and NASA Earth (0.67, Research Organization) sit nearly tied at position seven and eight, followed by NASA Mars (0.65, Research Organization) and SpaceX (0.64, Technology). Mark Hamill's presence at 0.67 — higher than SpaceX and matching NASA Earth — is the clearest cross-kind signal in the top 10: an actor whose audience shape aligns more closely with Hubble's than most space-adjacent brands do.

The broad shape here reflects an audience that tracks across institutional science, government space programs, and a strand of science-adjacent pop culture, without concentrating sharply on any single neighbor.
