In a planetary system far away from our own galaxy, we find a series of 6 planets all having a kepler’s constant of 7.02E-15 sec^2/m^3

- 1. If we were able to watch one of the planets orbit their star and make one full revolution in 300 earth days (how many seconds?), what would be the distance from the center of the star to this planet? (Hint: Kepler's 3rd Law)

- 2. Based on the information in the last problem, calculate the mass of the star in the middle of this solar system? How does it compare to the sun? (The sun's mass is 1.98 EE 30 kg)
- 3. Another planet M85 within this same solar system has a mass of 5.2E+26 and a distance from the star of 5.3 E+13 meters. Calculate the velocity of how fast this planet revolves around the star.
- 4. How much acceleration does the star provide to the planet M85 in its orbit?
- 5. How many seconds does it take for M85 to orbit the star? Convert to Seconds
