Unlike the moon, quasi-lunar moons are not gravitationally bound to the Earth. They are ephemeral companions, in cosmological terms, following their own path around the sun. Only at certain times do they come close enough to appear bound. In the case of 2025 PN7, its minimum distance is 299,000 kilometers, while at its farthest point it can reach 17 million km. For comparison, the moon remains at an average distance of 384,000 km from Earth.
