Thank you, I wound up thinking about it some more and I divided 1 Earth orbit period by the square root of 2 to get the days of rotation. Then I could calculate the speed of the orbit based on orbit perimeter divided by time. It seems to make sense, hopefully I worked it out with the right...
Homework Statement
Assume that a planet just like Earth is orbiting the bright star vega at a distance of 1AU. The mass of vega is twice that of the sun.
a. How fast is the Earth like planet traveling around vega?
b. How long will it take to complete one orbit around vega...
