Sextillion
discussing the count of a large number of objects, such as stars in the Observable Universe, the focus is not on calculating their literal quantity down to the last star. In such cases, understanding the order of magnitude is sufficient. It is considered that the number of stars in the Observable Universe is a figure with 22 digits, which is more conveniently represented as one followed by 21 zeros and written as 10 to the power of 21.
Moreover, this is a lower estimate. This means that there could be
as few as
or as many as
1 000 000 000 000 000 000 000,
9 999 999 999 999 999 999 999
The number of stars in the observable universe, as well as the number of transistors in all existing electronic devices of humanity, if Intel was truthful.
In one breath, we inhale about 10 sextillion molecules of air. The same number of molecules is contained in one gram of water.
