<strong>正确答案：B</strong><br>

解析：万有引力定律适用于宇宙中任何两个有质量的物体之间的相互作用，不仅限于天体，故A错误；根据万有引力公式F=G(m₁m₂)/r²，两个物体之间的万有引力大小与它们距离的平方成反比，故B正确；万有引力的方向总是沿着两个物体的连线方向，故C错误；万有引力常量G是卡文迪许通过扭秤实验测量得出的，故D错误。

<strong>正确答案：D</strong><br>
|
||
解析：根据重力加速度公式g=GM/R²，其中G为万有引力常量，M为地球质量，R为地球半径。当地球质量M不变，半径R变为原来的一半时，新的重力加速度g'=GM/(R/2)²=4GM/R²=4g，故答案为D。

<strong>正确答案：B</strong><br>
|
||
解析：根据万有引力提供向心力的公式GMm/r²=mv²/r，可得 satellite line speed v=√(GM/r)。当轨道半径r增大到原来的2倍时，新的线速度v'=√(GM/(2r))=v/√2，故答案为B。

解析：开普勒第一定律指出所有行星绕太阳运动的轨道都是椭圆，太阳处在椭圆的一个焦点上，故A错误；根据开普勒第二定律，行星与太阳的连线在相等时间内扫过相等的面积，因此行星在近日点的速率大于在远日点的速率，故B错误；开普勒第三定律表明所有行星的轨道半长轴的三次方与公转周期的二次方的比值都相等，故C正确；开普勒定律不仅适用于行星绕太阳的运动，也适用于卫星绕行星的运动，只是比值不同，故D错误。
