Galactic Mass Quiz

To calculate the approximate mass of the Milky Way Galaxy within the Sun's orbit, we need to use the relationship between orbital period, distance, and mass. According to Kepler's Third Law of Planetary Motion, the equation is given by: $$M = \frac{{4\pi^2d^3}}{{G(T^2)}}$$ where M is the mass of the galaxy within the Sun's orbit, d is the distance between the Sun and the galactic center, T is the period of the Sun's orbit, and G is the gravitational constant. Plugging in the values, we have: $$M = \frac{{4\pi^2(27000\text{ light-years})^3}}{{G(230\text{ million years})^2}}$$ Calculating this equation will give us the approximate mass of the Milky Way Galaxy within the Sun's orbit.

The Sun orbits the galactic center every 230 million years at a distance of 27,000 light-years.

The calculation tells us only the mass of the galaxy within the Sun's orbit.
