# Orbital Velocity of the Earth

The period of Earth's orbit around the sun is 365 days. Given that the mass of the sun is about $$2 \times 10^{30} \text{ kg}$$, compute the velocity to the nearest 1000 meters per second of the Earth as it orbits the sun. Approximate the orbit of the Earth around the sun as circular.

Useful constant: Newton's gravitational constant is $$6.67\times 10^{-11} \text{ N} \cdot \text{m}^2 / \text{kg}^2$$.
