And now, if you add up all the planets with all their different orbits and all their masses, you get this one shared center for the whole solar system. Solar system, and it moves. Sometimes it's inside the Sun, but sometimes it's outside. The last time it was inside the Sun was 2016, and the center of our solar system won't be back inside the Sun until 2027.
