What is the largest star in our solar system?

I think it’s a binary system, with the primary star being our sun.  One of the major stars is Sirius, the brightest star in the night sky.  If it was classified as a “star”, it would be about twice the size of our sun, but due to the way we measure, it’s counted as a “dwarf”.

The sun it is.  How many stars are in the solar system?

Including our sun and all the planets, there are 863,000,000,000 stars.

The number given is so large and precise.  Who counted them?

Scientists made a very high-resolution telescope, then they took a picture of the sky.  But, I know that some people just count stars by using binoculars, they say, “that one, and that one, and that one”, over and over, in a row until they get too tired.  But I know that scientists have also counted the same stars with the very large telescope, and they’ve gotten a very different result.

Is the Sun the closest star?
