A typical post picks up 112 interactions against 190K followers, an engagement rate of 0.059%. Measured over 44 original posts, its engagement rate beats 47% of 15,519 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 6.4K times each, and 1.76% of those impressions turn into an interaction. That is about 3.38% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 2.6 posts a day over the last 30 days, though only 37% of days saw any activity at all. Most posts go out around 12:00 UTC, and Tuesday is the busiest day of the week. Of the 44 posts sampled, 98% carry an image or video and 68% are part of a thread. The account's strongest tracked post pulled 6.4K interactions, about 57x its own typical post.

Compared with accounts its own size

Astropics's engagement rate beats 47% of the tracked X accounts closest to it in follower count (15,519 accounts, accounts of similar size (decile 8 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 60% 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 0.059%, Astropics sits above the 25th percentile of the 156,596 accounts in this comparison. That places it in the below the median band, which runs 0.022% to 0.127%.

Engagement rate as a share of followers, across the 156,596 accounts we have scanned enough to measure. The axis is logarithmic, because the top and bottom of this population are about 26,062 times apart and a linear axis would flatten everything below the median into a single point.

Posting timing

This account posts most often around 12:00 UTC, and Tuesday 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: 12:00 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

  • 98% 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.
  • 2% 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 573 characters, which falls in the over 280 characters band. Across the catalog, posts over 280 characters run 15% above the same accounts' other posts.

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.

    The Sun is constantly throwing material into space. Every second, about 1.5 million tons of charged gas leave the star as the solar wind and race outward through the solar system. Earth is mostly shielded from that flow. The planet's magnetic field bends the solar wind around us, so the surface stays protected even though the stream never really stops. Close to the poles the shield thins out. That is where auroras form, and where strong solar storms can still interfere with satellites and radio signals. This NASA Goddard animation shows that interaction as it happens.

    Cassini photographed Saturn from high above the northern hemisphere on 2 April 2014. The hexagon is visible at the pole, the rings run across the top and bottom of the frame, and a long pale storm cuts through the mid-latitudes. The spacecraft's inclined orbit made that angle possible, looking down on the pole rather than seeing the planet only from the side.

    Two black holes spiral together and merge in this simulation from the SXS Project. As they close in, spacetime warps around both horizons until the pair becomes a single, larger black hole. The visualization is based on numerical relativity calculations used to model the gravitational waves such collisions produce.

    Fun fact: If we replaced our Sun with Betelgeuse, this red supergiant would be so enormous that its surface would extend beyond Jupiter's orbit (swallowing Mercury, Venus, Earth, and Mars in the process)! It is roughly 700 to 1,000 times larger in diameter than the Sun, making it one of the biggest stars visible to the naked eye.

Reading these numbers

A typical post picks up 112 interactions against 190K followers, an engagement rate of 0.059%. Measured over 44 original posts, its engagement rate beats 47% of 15,519 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 6.4K times each, and 1.76% of those impressions turn into an interaction. That is about 3.38% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 2.6 posts a day over the last 30 days, though only 37% of days saw any activity at all. Most posts go out around 12:00 UTC, and Tuesday is the busiest day of the week. Of the 44 posts sampled, 98% carry an image or video and 68% are part of a thread. The account's strongest tracked post pulled 6.4K interactions, about 57x its own typical post.

What is Astropics's engagement rate on X?
Astropics (@astro4pics) has an engagement rate of 0.059%, based on the median interactions across 44 original posts from the last 30 days against 189,658 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
Is that a good engagement rate?
At 0.059%, Astropics sits above the 25th percentile of the 156,596 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 @astro4pics have real engagement?
Its engagement rate beats 47% of the tracked X accounts closest to it in follower count (15,519 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 @astro4pics post?
Most posts go out around 12:00 UTC, and Tuesday is its busiest day, at roughly 2.57 posts per day across the measured window.
