Engagement
A typical post picks up 205 interactions against 398K followers, an engagement rate of 0.051%. Measured over 59 original posts, its engagement rate beats 42% of 3,758 tracked accounts of a similar size, which puts it in the middle of its size range rather than at either end. Posts are seen about 7.5K times each, and 2.73% of those impressions turn into an interaction. That is about 1.88% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 2 posts a day over the last 30 days, though only 43% of days saw any activity at all. Most posts go out around 20:00 UTC, and Sunday is the busiest day of the week. Of the 59 posts sampled, 100% carry an image or video and 37% link out. The account's strongest tracked post pulled 2.2K interactions, about 11x its own typical post. Recurring topics include #otd, #tdih, #airspacephoto.

Compared with accounts its own size
National Air and Space Museum's engagement rate beats 42% of the tracked X accounts closest to it in follower count (3,758 accounts, accounts of similar size (decile 6 of 10)). A percentile is spread evenly by construction, so 50 really is the middle of that group and 90 really is its top tenth.
On engagement per impression rather than per follower it beats 72% of the same group. When those two numbers disagree, the gap is about how far its posts travel rather than how people react to them.

Posting timing
This account posts most often around 20:00 UTC, and Sunday is its busiest day of the week. The bars below are the catalog-wide pattern, with this account's own busiest slot marked. They do not show how this account performs at each hour: we keep one aggregate per account, not one per hour, so that measurement does not exist in our data.

On this day in 1961, a Douglas DC-8 became the first commercial airliner to break the sound barrier during a test flight. The aircraft exceeded Mach 1—the only intentional supersonic flight by an airliner other than the Concorde and the Tu-144. More: https://t.co/YEIuX1CkLj https://t.co/zLp1Sh60Wf

55 years ago today, the M2-F3 lifting body went supersonic for the first time. The rocket-powered M2-F3 was launched from beneath a B-52 mothercraft at an altitude of 45,000 feet and would glide to a landing. This photo of it launching from a B-52 was taken earlier that month. https://t.co/mhc8EHFoZh

Katherine Johnson #OTD in 1918. As a mathematician who calculated trajectories for some of NASA’s most important missions, her contribution to history cannot be overstated, though it was overlooked for decades. More on her legacy: https://t.co/pNkhd90WKe https://t.co/J95O6kMmmQ

- What is National Air and Space Museum's engagement rate on X?
- National Air and Space Museum (@airandspace) has an engagement rate of 0.051%, based on the median interactions across 59 original posts from the last 30 days against 397,932 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.051%, National Air and Space Museum sits above the 25th percentile of the 36,521 accounts in this comparison. Those comparison accounts are all large ones, because our scanning cadence is weighted towards big accounts, so this is a ranking among peers of similar scale rather than a ranking across X.
- Does @airandspace have real engagement?
- Its engagement rate beats 42% of the tracked X accounts closest to it in follower count (3,758 accounts), which puts it in the middle of its size range group. Ranking inside a size band matters because engagement rate falls as accounts grow, so a raw rate would mostly re-measure the follower count. It is a starting point for a look at follower quality, not a verdict on it.
- When does @airandspace post?
- Most posts go out around 20:00 UTC, and Sunday is its busiest day, at roughly 1.97 posts per day across the measured window.
