How does the sun move from a heliocentric perspective?
. The Moon moves around the Earth, the Earth moves around the Sun, the Sun (and our entire solar system) orbit the center of the Milky Way galaxy. All the other galaxies are also moving, and it doesn’t make any sense to assume that the Milky Way isn’t moving as well – but there is no “stationary spot” in the universe that we can use to measure the Milky Way’s movements.
