The Sun is 99.98% of the mass of the Solar System. Sun's overwhelming mass compared to the other planets controls their orbits.

Sag A" is only 0.003% of the mass of the Milky Way Galaxy.

  • Sag A* has a puny 4 million solar masses.

  • Milky Way Galaxy has 200 billion stars plus a much greater mass of Dark Matter, together totalling 1.2 to 1.9 trillion solar masses.

  • 4 million vs over 1.2 trillion solar masses. The stars and the Dark Matter should have a much greater control of the Sun's orbit. And prevents the Sun from flying away.
