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

A million peas can fit in a large bag that you could lift. A handful is enough to hold a million grains of sand. And from a million letters, you can create a single, quite sizable book (for instance, the complete Bible consists of 2.5 million letters).

You can even count to a million, and Jeremy Harper did it in 2007. It took him 89 days, spending 16 hours each day on the task.
