Speed to keep Sun stationary

  1. Mar 27, 2013 #1
    If I was in the car driving westward, how fast would I have to drive in order for the Sun to appear as if it is not moving.. In other words if I start driving at 1pm, how fast do I have to go so i'm always at 1pm.?

    Depends on what your latitude is. The higher the latitude, the slower you need to go. At the equator the rotational velocity of the Earth is around 1,670 km/h, so you'd need to go that fast to keep the Sun stationary.
