Can a parent body be tidally locked with a moon, so if one was standing on the planet the moon would appear in the same location in the sky day and night?

If the plane of the orbit is exactly the same as the plane of the sun? Yes. The moon orbits the Earth every 30 days, but we certainly don't get a solar eclipse every month.vladpaln said:Does that mean that somewhere on the planet there is a daily eclipse??
Two way tidal lock is a phenomenon in which a planet and its moon are gravitationally locked to each other, causing them to always show the same side to each other as they orbit. This means that one side of the planet or moon is constantly facing the other, similar to how the moon always shows the same face to Earth.
Two way tidal lock occurs because of the gravitational forces between the planet and its moon. The stronger gravitational pull from the larger object (usually the planet) causes the smaller object (usually the moon) to become tidally locked, meaning that its rotation and orbit are synchronized.
Not all planet and moon combinations are capable of becoming tidally locked. Certain conditions must be met, such as the mass and distance between the two objects. For example, the moon is tidally locked to Earth, but Earth is not tidally locked to the moon.
Two way tidal lock can have various effects on the planet and moon, such as causing the moon's orbit to become more circular, slowing down the planet's rotation, and possibly causing tidal heating (a phenomenon in which the gravitational forces create heat within the objects).
No, Earth and the moon are not at risk of becoming tidally locked. The moon's orbit is gradually increasing, meaning that it is moving further away from Earth, making it impossible for them to become tidally locked. However, this process is very slow and will not occur within the lifespan of humans.
