The Solar System proxima century next to our solar system is a smaller star than the Sun, but it is said that we can not see it with the naked eye. It is 4.5 light years away from our Earth.

So a star twice the size of proxima is 9 light years away, but we can not see a star 18 light years away.

With this concept we can directly see how many stars in the milky way galaxy we see because this galaxy has a diameter of 105700 light years.
It’s natural to feel a mismatch.
