WebYes you would, at least not accounting for the earth's revolution around the sun. We tend to equate time with where we are in relation to the earth's rotation (noon being about where the sun is at its highest point, midnight at its lowest) so if you moved to keep the sun at the same relative position, you would keep experiencing that time. WebUnless you are doing milliarcsecond astronomy, you can ignore that bias and rotation. For most applications, J2000/FK5=ICRF=ICRF2. The first item, that the Earth's rotation axis …
