Left: stable orbits are possible for prograde moons located outside the planet’s Roche limit and inside half the Hill sphere. This diagram has been drawn to scale for a Luna-sized satellite orbiting TOI 700 d. Right: if the Roche limit is larger than half the Hill sphere, no prograde moons would be stable.
