The top 10 neighbors in NASA's similarity graph span six different subcategories — actors, magazines, blogs, politicians, news publishers, and finance brands — with no single kind dominating the set.
The shape is broad: scores run from 0.89 down to 0.82 across the top 10, with no single neighbor pulling far ahead of the rest. National Geographic leads at 0.89, the only magazine in the top 10, followed by Olivia Munn (0.86) and The Dodo (0.85) — an actor and a blog, respectively. Arnold Schwarzenegger (0.85) and Science News (0.84) round out the top five, one a politician subcategory and the other a news publisher. Coinbase (0.84) and Bittrex (0.82) are the two finance brands in the top 10, a pairing that sits alongside Curiosity Rover (0.83) — the only neighbor that shares obvious thematic proximity to NASA — and actors Alison Brie (0.83) and Taika Waititi (0.82). NASA JPL (0.83) is the sole Research Organizations entry in the top 10, and the only neighbor that shares NASA's own organizational orbit.
The cross-kind character of this cluster is the defining feature: the audience that follows NASA is shaped less by science content specifically than by a broad, curious profile that overlaps equally with entertainment figures, finance platforms, and general-interest media.
