NASA's Perseverance Mars Rover sits at 0.96 — the strongest pull in NASA InSight's top 10 — but the rest of the neighbor set fans out across a wide range of subcategories, none of which are Research Organizations. That cross-kind breadth is the defining structural feature here.

The shape is broad. After Perseverance, the scores compress into a tight band: Schitt's Creek (0.93, TV Shows), Men in Blazers (0.92, Podcasts and Radio), Jon Stewart (0.92, Comedians), and Dan Levy (0.92, Actors) all cluster within a few hundredths of each other. No single neighbor dominates after position one. Tallying the top 10 by subcategory: Actors appears twice (Dan Levy and Eugene Levy, 0.90), TV Personalities twice (Ken Jennings at 0.91 and Katie Nolan at 0.91), and Comedians once (Jon Stewart). The remaining slots go to a TV show, a podcast, an author (Brené Brown, 0.91), an outdoors brand (REI, 0.90), and a comedian (Sarah Beattie, 0.90). Perseverance is the only fellow Research Organization in the top 10; every other neighbor arrives from entertainment, media, or lifestyle.

That pattern — one tight science peer surrounded by comedians, actors, TV personalities, and a podcast — suggests an audience that follows space exploration as part of a broader diet of culturally engaged, media-literate content rather than as a specialist science interest alone.
