The top 10 neighbors for NASA's Perseverance Mars Rover span authors, comedians, TV personalities, podcasts, a TV show, and a fellow research organization — with no single dominant pull and scores compressed between 0.96 and 0.90.
The shape is flat. NASA InSight leads at 0.96, the one neighbor that shares Perseverance's own subcategory (Research Organizations), but the remaining nine come from entirely different kinds. Brené Brown (0.93) and Schitt's Creek (0.93) sit nearly tied for second, followed by the soccer podcast Men in Blazers (0.93), TV personality Ken Jennings (0.93), and comedian Jon Stewart (0.93). Katie Nolan (0.92), satire account PatriotTakes (0.92), author Glennon Doyle (0.91), and journalist Keith Law (0.91) round out the ten. Tallying subcategories across the ten: Authors (2), TV Personalities (2), Comedians (1), Podcasts and Radio (1), TV Shows (1), Humor Memes and Satire (1), Journalists (1), Research Organizations (1). No single subcategory dominates; the cluster is genuinely mixed across Celebrities and Influencers and Marketing Channels, with NASA InSight the lone same-kind neighbor.
That breadth — a research organization whose nearest audiences also follow self-help authors, a Canadian sitcom, a soccer podcast, and political satirists — points to an audience defined less by subject-matter interest than by a consistent cross-category behavioral profile.
