In 2005 a planet was found revolving about a distant sunlike star in 3.88 days. The radius of its orbit is 1700000 km.
what is its linear velocity (in km/h) about its star?
:
Assuming the orbit is circular, find the circumference dist, divide by the time,converted to hrs.
v = %282%2Api%2A1.7%2810%5E6%29%29%2F%283.88%2A24%29
v = 114706 km/hr
