A typical post picks up 2.7K interactions against 2.1M followers, an engagement rate of 0.129%. Measured over 36 original posts, its engagement rate beats 75% of 20,444 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 86K times each, and 3.10% of those impressions turn into an interaction. That is about 4.18% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 1.7 posts a day over the last 30 days, with activity on roughly 57% of days. Most posts go out around 17:00 UTC, and Friday is the busiest day of the week. Of the 36 posts sampled, 72% carry an image or video, 11% are part of a thread and 19% link out. The account's strongest tracked post pulled 140K interactions, about 52x its own typical post.

Compared with accounts its own size

Everyday Astronaut's engagement rate beats 75% of the tracked X accounts closest to it in follower count (20,444 accounts, accounts of similar size (decile 10 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 79% 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.

Where this sits in the catalog

At 0.129%, Everyday Astronaut sits above the 25th percentile of the 204,491 accounts in this comparison. That places it in the below the median band, which runs 0.024% to 0.143%.

Engagement rate as a share of followers, across the 204,491 accounts we have scanned enough to measure. The axis is logarithmic, because the top and bottom of this population are about 22,891 times apart and a linear axis would flatten everything below the median into a single point.

Posting timing

This account posts most often around 17:00 UTC, and Friday 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.

Engagement by hour posted, UTCTwenty-four bars, one per UTC hour. Each bar shows how posts published in that hour compare with their own authors' median engagement. Bars above the centre line ran higher than the median, bars below ran lower. A marker flags Busiest hour: 17:00 UTC.

Formats this account uses

Its own posting mix on the left, and what each of those formats does across every account we track on the right. Only formats where the effect clears our publish test appear here, so an empty row is a format we could not measure rather than one that does nothing.

This account's posting mix compared with catalog-wide effects
FormatThis accountCatalog effect95% intervalAccounts behind it
Image or video72% of posts+111%+108% to +115%34K

  • 72% of this account's sampled posts carry an image or video. Across the catalog, posts with an image or video run 111% above the same accounts' other posts.
  • 19% of its posts carry a link off X. Across the catalog, posts with an outbound link run 41% below the same accounts' other posts.
  • Its average post runs 269 characters, which falls in the 180 - 280 characters band. Across the catalog, posts of 180 to 280 characters match the same accounts' other posts almost exactly.

These are catalog-wide differences applied to this account's own posting mix, not a measurement of how each format performs for this account specifically. We keep one median per account, not one per format per account, so the second thing is not something this data can tell you.

    Looks like we will probably catch the ship with the tower in a few months. If there had been a tower out to sea where we practiced landing the ship, it would have been caught. First reflight of the ship will be either end of this year or early next. That will be a fork in the road of history for consciousness reaching the stars.

    Now targeting Friday, July 24 for Starship’s thirteenth flight test, due to weather. A key objective for the flight test is to get clear imagery from the ground of Starship’s heatshield as it flies at a higher dynamic pressure during ascent, which won't be possible with today's weather conditions. Visibility is forecast to be ideal for a Friday attempt.

Reading these numbers

A typical post picks up 2.7K interactions against 2.1M followers, an engagement rate of 0.129%. Measured over 36 original posts, its engagement rate beats 75% of 20,444 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 86K times each, and 3.10% of those impressions turn into an interaction. That is about 4.18% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 1.7 posts a day over the last 30 days, with activity on roughly 57% of days. Most posts go out around 17:00 UTC, and Friday is the busiest day of the week. Of the 36 posts sampled, 72% carry an image or video, 11% are part of a thread and 19% link out. The account's strongest tracked post pulled 140K interactions, about 52x its own typical post.

What is Everyday Astronaut's engagement rate on X?
Everyday Astronaut (@Erdayastronaut) has an engagement rate of 0.129%, based on the median interactions across 36 original posts from the last 30 days against 2,070,389 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
Is that a good engagement rate?
At 0.129%, Everyday Astronaut sits above the 25th percentile of the 204,491 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 @Erdayastronaut have real engagement?
Its engagement rate beats 75% of the tracked X accounts closest to it in follower count (20,444 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 @Erdayastronaut post?
Most posts go out around 17:00 UTC, and Friday is its busiest day, at roughly 1.73 posts per day across the measured window.
