Suppose that you used some geometry and kinematics to estimate that the Earth goes around the Sun with an orbital speed of approximately 30,000 m/s (60,000 mph), and that the Sun is approximately 150 million kilometers away from the Earth. Use this information to estimate the mass of the Sun.

• B. 2.02×10²⁹kg
• C. 2.02×10³⁰kg
• D. 1.42×10¹⁷kg
