How many stars are there in the sky? joke

1. If you are on the ground, you can count them all under ideal conditions.

Visible to the naked eye all day, there are 6 first-class stars, 20 first-class stars, 46 second-class stars, 34 third-class stars 134, 458 fourth-class stars, 50 fifth-class stars 1476 and 4840 sixth-class stars, totaling * * * 6974.

There are 6974 "stars all over the sky" in a narrow sense.

2. If it is a broad question: How many stars are there in the universe, it is really difficult to count, because the size of the universe is unknown, so the number of stars in the universe cannot be counted.
