The Venus radius of 6085 +/- 10 kilometers, deduced from combining observations made with the Venera 4 and Mariner V space probes is incompatible with the value of 6050 +/- kilometers determined from Earth-based radar mesurements.
金星半径为 6085 +/- 10 公里,是结合金星 4 号和水手 5 号太空探测器的观测结果推断出来的,与从基于地球的雷达测量得出的 6050 +/- 公里的值不一致。
