Io orbits Jupiter at a distance of six planetary radii from the planet's center once every 42 hours. if Jupiter completes one rotation every 10 hours, use Keplers third Law to calculate how far from the center a satellite must orbit to appear stationary above the planet.
A scientist has evidence that a newly discovered planet has a mass of 7.0\times 10^(24) kilograms and a volume of 3.5\times 10^(12) cubic kilometers. What is the planet's density?
