The astronomer (and the rebellion) in me always comes to a hiccup when this particular term comes up.
Does anyone actually know what "one order of magnitude" really means?
One order of magnitude is the 5th root of 100 or ca 2,511886431509580111085032067799328 (according to my DM42)
Astronomically, stars are odered by brightness in magnitudes.
A magnitude 6 star is the faintest one (normally) can see with the naked eye in a lightunpolluted sky. A magnitude 1 star is 100 times brighter. Each magnitude is determined by ~2,512^x where x starts with 0 at mag. 6 (2,512^0=1) and 5 (2,512^5=~100) at mag. 1. So, a mag. 6 star is "1" bright and a mag 1 star is "100" bright.

Star magnitudes

Yes, and a continous merry christmas and a coming prosperous new year to all.

You got me! I did forget to mention that I meant the commonly used definition of10^n and not the astronomical definition

The Cambridge dictionary says:
Meaning of “order of magnitude” in the English Dictionary
A level in a system used for measuring something in which each level is ten times larger than the one before:

Eg. These processor speeds have recently increased by two ordersof magnitude (= by a hundred times).

Just saying..
