The rise of heliocentrism is well studied, and the "center of the universe" shifted from Earth to the sun once the dust settled on the Galileo affair. But when did we realize that the sun is not the center, but merely one of billions of stars in a large galaxy?

    Hi, and welcome to History:SE. Isn't this answered in the Wikipedia article on Heliocentrism? "With the observations of William Herschel, Friedrich Bessel, and other astronomers, it was realized that the Sun, while near the barycenter of the Solar System, was not at any center of the universe." – sempaiscuba May 7 at 23:39
  • There're still a lot of people still believes that Earth is flat and located in the center of the universe – Vishwa May 8 at 5:39
  • Check out this Physics Stack Exchange question. The big answer is that the sun is not the center of the solar system, but it depends how you define your reference system. – axsvl77 May 8 at 11:09
