What three examples of reference points that are stationary relative to earth?

Three examples of reference points that are stationary relative to Earth include the North Star (Polaris), which provides a fixed point in the sky for navigation; the geographic poles (North and South Poles), which are fixed locations on the Earth's surface; and a specific point on the Earth's surface, such as a landmark or building, which remains in the same location over time. These reference points help in measuring movement and position relative to the Earth.
