An object falling at terminal velocity is in equilibrium. Equilibrium only refers to the forces on an object, and not the object itself.
Satellites or moons are not in equilibrium. As they are in a circular orbit, they are constantly changing direction. This means a force is acting on them, changing their motions, and so they are actually accelerating. Acceleration, as a vector quantity, can occur if an object changes either velocity or direction. So the moon is actually accelerating but it's not moving any faster, imagine that.

All objects including passengers in a uniformly moving bus train plane etc.and including the bus, train, plane etc are all in equilibrium while in motion provided they move with uniform speed.

The MOON. The moon is in motion. It is also in equilibrium with earth's gravity and in fact, is really part of the earth.
