No you can't. The star at the center of our solar system is "the sun". It's the only sun. There is no other sun. That's its name. It's not the same case as the moon. Not every star is a sun. Only ours is, because that's its name. It's a nifty little sci-fi trope to call every star with bodies orbiting it a sun, but that's not the case realistically.xdgt said:you can call any other star sun
The sun is -only- the star at the center of -the- Solar System (ie, our solar system). Any other star in any other solar system is just a star. And Sol is just the Latin name of the sun. I don't speak Latin, so bug off.
