Mathematical questions on Astronomy

7 mathematical questions involving astronomy.

For example, The Sun is orbiting around the entire galaxy such that it completes a full orbit once every 2×10⁸ years. Using careful measurements of phenomena known as masers, we have accurately 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 that has a circumference of C=2πR.) Report your answer in kilometers per second.
