There are somewhere around a septillion stars in the observable universe.

在可觀測的宇宙中，大約有七十億顆恆星。

But there are only about five thousand stars in the sky visible to an average human eye.

但普通人的眼睛能看到的天空中的星星只有五千顆左右。

And you can only every see half of them from one side of the earth.

而你只能從地球的一側看到它們的一半。

BONUS FACT: The whole universe probably contains infinitely many stars, because it's probably infinite in size. But it'll be hard to check.

額外的事實：整個宇宙可能包含無限多的恆星，因為它的大小可能是無限的。但很難查證。
