check this formula and calculate it

• π – Mathematical constant pi (≈ 3.14159)
• r – Orbital radius (distance from center)
• c – Speed of light in vacuum
• T – Orbital period (time for one complete revolution)
• G – Gravitational constant
• h – Planck constant
• ν (nu) – de Broglie frequency

Sure, in regimes where it is appropriate to have a de Broglie frequency and use circular orbits approximated by Newtonian gravity.

It's only my on personal bias, but I hope we don't see a lot of posts like this.
