Imagine for a second that Earth no longer rotates around its axis. It still revolves around the Sun.
However, would the Earth:
- face the same way towards the Sun as it goes around it (permanent time of day everywhere, e.g. Europe always looks towards the sun, while China has permanent night)
- not rotate at all (a day that lasts a whole year, e.g. the Earth would be to the Sun as the Moon currently is to the Earth)?
I'm trying to simulate the solar system and I need to know if I, once I rotate the Solar system (to simulate rotation of the Sun), have to rotate the Earth back for the equal angle or not.
