地球绕太阳运行的轨道半长轴为1.50×1011 m,周期为365天;月球绕地球运行的轨道半长轴为3.8×108 m,周期为27.3天;则对于绕太阳运动的行星

R3
T2
的值为______,对于绕地球运动的卫星
R3
T2
的值为______.

答案

1天=24×3600s

地球绕太阳运动的

R3
T2
=
(1.50×1011)3
(365×24×3600)2
m3/s2
=3.4×1018 m3/s2

月球绕地球运动的

R3
T2
=
(3.8×108)3
(27.3×24×3600)2
m3/s2
=9.8×1012 m3/s2

根据开普勤第三定律可得:绕太阳运动的行星

R3
T2
=3.4×1018 m3/s2;绕地球运动的卫星
R3
T2
=9.8×1012 m3/s2

故答案为3.4×1018m3/s2;9.8×1012m3/s2
