Tags Orbital Orbital period Period Planet In summary, the equation P2 = (4 * pi2 * a3)/(G(M+m)) can be used to find the orbital period of Earth, where P is the orbital period, a is the semi-major axis, G is the gravitational constant, M is the mass of the sun, and m is ...
According to Kepler's third law,the orbital period T of a planet is related to the radius R of its 相关知识点: 试题来源: 解析 即T ^ 2=t ^ 2 * R ^ 3 / r ^ 3 (R / r=4.97,故R ^ 3 / r ^ 3 =122.763473) 两边开方:T=t * (R ^ 3 / r ^ 3) ^ 0.5=11.07986791 (years...

When we think of a moon, we most likely think of the Earth's moon. But the word "moon" can actually mean any body that goes around a planet. That makes 2020 CD3 a moon of the Earth. Or perhaps a mini-moon. Scientists say 2020 CD3 is probably only about 6-12 feet (2-3.5 ...
