How many miles does take for one orbit?

approx. 200 to 260 million years
its very uncertain since we can just guess on other galaxies rotation.
Whats the circumfence of a circle with a radius of 30.000 to 45.000 lightyears (distance sun/galactic-center)?
however we are going to travel more than 190000 lightyears one way around

The Sun is revolving around the center of the Galaxy at a speed of half a million miles per hour, yet it will still take 200 million years for it to go around once. Do you feel like you are moving at that speed through space? If you did, you would certainly need a seat belt! When we run, we feel the wind on our bodies because there are molecules which make up the air that push against our bodies. But there are very few molecules in the space between the stars. So there is nothing to push against our planet so that we "feel" like we are rushing around at half a million miles per hour.

It takes the solar system about 225-250 million years to complete one orbit (a galactic year),[18] and so is thought to have completed about 20-25 orbits during its lifetime or 0.0008 orbit since the origin of humans. The orbital speed of the solar system is 217 km/s, i.e. 1 light-year in ca. 1400 years, and 1 AU in 8 days.
