The sun is orbiting around the entire galaxy such that it completes a full orbit once every 2 × 10 8 years. using careful measurements of phenomena known as masers, we have acurately measured the distance to the center of the galaxy to be approximately 8 kpc (kiloparsecs). this is enough information to calculate our orbital speed. (assume that the path the sun takes is a circle which has a circumference of c = 2 ? r .) report your answer in kilometers per second.
