When something makes sense, you are adding subjective value to it. There is nothing objective about something making sense; it is dependant on your particular brain, and it tends to be uncontrollable and seemingly arbitrary. You could be stuck learning a math problem, fall asleep, and in the morning everything suddenly makes sense.
The epicycles of a geocentric universe make sense, for example, so try to substitute "making sense" with a more measurable claim: the heliocentric model makes the least number of predictions, etc.
It is difficult to divorce the science from the scientist, but we can at least be mindful of where one ends and the other begins.
If you'd like to be more exact you can say that when considering motion of the planets of Solar system taking the system's barycenter or the Sun's center of mass as a reference point allows to obtain their equations of motion in the most simple form.
Heliocentric model was a very big step forward from the epicycles and earlier astronomical concepts. Astronomers were making observations for centuries but in the geocentric coordinates they were too confusing to make any general assumptions about the laws of motion. Adoption of Heliocentrism and Kepler's study of Martian orbit paved way for Newton's Theory of Gravitation.
