Why do the stars stay in the same place if the Earth is rotating and why do the stars stay in the same place if the Earth is rotating?
The stars are very far away. The rotation of the Earth causes all the stars to appear to rotate at the same speed (very nearly) so that their positions relative to one another do not change. That's because the Earth's axis points at a point in the sky around which everything appears to move, including the stars. In the North, this happens to be very close to a star called Polaris, or the North Star. As the Earth rotates on its axis it makes it look like the stars are moving through the night sky. Also, as the Earth orbits the Sun it changes the stars that we see at any given time of the night. Hubble's law explains that the reason most galaxies are moving away from one another is because the whole universe is expanding. The axis of rotation is different from the magnetic poles. This difference creates force for the earth to rotate on its axis. The same is the case with all planets in the Solar System. Moon doesn't have Magnetic field; hence it does not rotate on its axis. The stars seem so fixed that ancient sky-gazers mentally connected the stars into figures (constellations) that we can still make out today. But in reality, the stars are constantly moving. They are just so far away that the naked eye cannot detect their movement. The reason is that they relatively static, but the earth spins so they appear to move in relation to us. Look at the position of the stars when it first gets dark and they do this again two hours later. Imagine standing on that rolling ball. You might worry that if you didn't keep peddling your feet you'd fall off. But the reason you won't fall off the Earth is because of the force of gravity. This pulls us towards the middle of the Earth, and keeps our feet firmly on the ground.
Murtala,
I fear that you've fallen into Dr Naresh's trap.
He is not asking these questions in good faith (unless he truly did not know that the Earth rotates)
He posts a naive question so that someone can reply to it, allowing him the semblance of imparting wisdom.
I've reported this abuse of ResearchGate - but to no avail.
