Not a astrophysist at all but Given that we know the velocity of the solar system roughly* and the have a good estement for the mass of the milky way we can do fancy orbital mechanics math to plot the orbit.
Simmilar to pluto since it has not completed an orbit since its discovery in the 1930s, yet we still know it orbits the sun
