measurement in either km/h or mph would be most helpful. I believe the formula is something like distance traveled / time =3D kmh or mph (d/t=3Dkmh mph). The time is approx 365 days or approx 8760 hours. How do I find the distance and is my formula correct? The average radius of the Earth's orbit around the Sun is 93 million miles, so the distance is Do you think it is possible that there could be another planet making the same orbit as Earth? This planet would have to be on the exact opposite side of the Sun. If there was, would we have seen it by now? It is impossible for there to be another planet on the opposite side of the Sun from the Earth, in the same orbit. We would have seen the gravitational effect of this planet on other planets, and, because the Earth's orbit is an ellipse, not a circle, we probably would have seen the planet as well. I am inquiring about the difference between the pull the Sun has on the Earth and the pull the Moon has on the Earth. I am hoping you could show me the calculations physicists use to determine how many times greater the Sun's pull is compared to the Moon's pull. Has anyone studied the effect of the Sun's gravity on the motion of objects that are near Earth? Isn't the Sun's gravitational pull much more powerful than the Earth's? As Isaac Newton figured out, the force
