Answer to Question 1

Radar studies of Venus finally determined that Venus' rotation rate is 243 days, retrograde. Studies of its entire surface from Earth, using radar, is complicated by the fact that almost the same face of Venus appears pointed towards Earth when the two planets are closest.

TRUE
