Smallest orbital rockets by height?

Question

Which orbital rocket is the smallest in height (or length) that ever launched?

Would be nice to know the second and third place too.

Similar questions:

SS-520 is also the answer to: How small could an orbital rocket be? and Do launchers using only solid propellant exist?, and Why isn't there a rocket to launch a single cubesat?, and Is it possible to build a rocket with 2kg payload?... — uhoh, Oct 27 '20 at 00:40
...and What is/was the smallest orbital launch system, by total mass? and also see If there “won't be” rockets to launch individual cubesats, then why did JAXA build exactly that? (SS-520-xx). — uhoh, Oct 27 '20 at 00:40

That is as far as I can tell the SS-520, placing a 4kg payload into LEO in 2018, with the total length of the launch vehicle being 9.54 meters.

If this record has not been surpassed after 2018, it still stands.
