Would 1 side of the earth face the sun at all times if earth stopped spinning?

Theoretically, if the earth stopped actually spinning, would it be permanent daytime on only 1 part of the earth, since it is orbiting around the sun, or would it be daytime for a long time, and then night for a long time?

    If the earth stopped spinning completely, a day-night cycle would take one year, the same time it takes for the earth to make a full rotation around the sun.

    In space, however, orbiting bodies never completely stop spinning. Think about the relationship between the earth and the moon. The moon slowly spins around 360 degrees each time it orbits the earth. This is why we only see one side of it.

    As the earth's spinning slows down over many millions of years, it will eventually reach a state where one side always faces the sun, and one side always faces away.

    When you say that the earth stop spinning, do you mean that only one side of the earth faces the sun while orbiting around it? In this case, I think the side of the earth that is not facing the sun at all, will have night all the time. The side of the earth that is facing the sun, will have a long daytime and a short night time, due to the fact that the moon still orbit earth. I hope that helps ^_^..

    No, because if the Earth stopped rotating it would still orbit the sun, and that would, over the course of the year, move every part of the Earth into sunlight.

    Try this.

    Put a lamp (this is the sun) in the middle of the room.

    Face a wall, and without changing the wall you face move around the lamp in one big circle.

    You (the Earth) aren't rotating, but as you move around the lamp (the sun) each part of you faces the lamp at some point in the orbit.

    The only way the Earth would have a year-long day (meaning one side always faces the sun) would be if the Earth rotated in the same length of time it orbits the sun (a day would be a year long). That is the situation with the moon - it orbits the Earth in about 29 days, and it's rotation period is the same length of time.

    i'm hoping the 5 people who suggested we would fall off have been joking. in the quick term the factors may be horrendous, great tsunamis, hurricanes etc, in the long term sometime may be the dimensions of a 300 and sixty 5 days. the sunlight hours area of the planet might replace into boiling warm mutually as the night time area will freeze. life purely does not be achieveable. The earth's spin is slowing down already. it fairly is being brought about by the moon. because it circles the earth it fairly is gravity pulls on the water in the oceans inflicting the tides that are slowly slowing the rotation of the earth. ultimately the day would be 28 days long. yet this might take an relatively long term.

    It would not be permanent daytime on 1 part of the earth. For that to happen (much like the moon's near half permanently faces the Earth), the Earth would not stop rotating; its rotation period would simply equal its revolution period.

    If the Earth stopped rotating altogether, then each spot on the Earth would be in sunlight for 1/2 of the year and darkness for 1/2 of the year. So your second hypothesis the correct one.

    no, the sun would rise and set once a year. if the earth had a 1:1 spin like mercury or the moon it would face the sun at all times. 1:1 spin means it spins the opposite way it revolves around an object and at the same speed.

    No because Earth would still orbit around the sun.

    to see this, draw a point on a piece of paper to represent the sun. then hold your pen some distance from the point to represent the earth. now draw a circle (or ellipse) to represent earth's orbit around the sun. while you do this, do not let the pen rotate and notice which "sides" of the pen face the sun during the journey.

    well, if you ask me every hemisphere will have a turn at the sun.Because if you draw a picture with the sun in the middle and the earth at the bottom, with a line on top,bottom,left and right of earth showing the side of light. then just picture it moving without turning. Do you see it? first the top then the right then the bottom then the left (if u move it to the left first).(referring to hemispheres)

    I think that it would be day for a very long time and eventually change to darkness for a while. If it stopped spinning, it would still have a lot of inertia and mass to keep it moving in the same direction until it slows down eventually.
