A star is observed to undergo circular orbit around the black hole located at the centre of the Milky Way galaxy. The orbital period is measured to be 16 years and the distance between the star and the black hole is determined to be 1000 Astronomical Units. Estimate the mass of the black hole in units of the Solar mass, and explain any approximations you make in your calculation.
