Planet Motion Trajectory is NOT An Ellipse Main Idea I- Why The Moon Motion Is An Elliptical (or Circular) Trajectory? - Earth moves daily a distance =2.58 mkm - Earth motion direction is straight trajectory approximately declines by 0.9856 degrees daily to complete 360 degrees during 365.25 day completing a full revolution around the sun - The moon has to move by this same data to save his connection with Earth (otherwise The Moon and Earth will be separated from each other) Shortly - Earth moves in straight trajectory with decline 0.985 degrees – the moon motion trajectory can't be a circular or an elliptical trajectory otherwise he will loss the Earth and will separate from her Let's explain more clearly - Earth Motion Trajectory is a straight line approximately (daily) because Earth motion declines only 0.985 degrees from the horizontal…. The moon can't move in any circular or elliptical trajectory around Earth –because if he does that earth and moon will be separated from each other! - But we see the moon moves in elliptical trajectory during the month, revolving around Earth a complete revolution! How to understand that Because It's A Wrong Vision - The Moon Motion effects On Our Vision and forces us to see any planet motion trajectory as an ellipse - The moon himself doesn't move in any elliptical trajectory but the moon motion effects negatively on our vision and forces us to see the moon motion trajectory as an elliptical trajectory… Conclusion Solar Planet Motion Trajectory Is Not An Ellipse – But We See It As An Ellipse Because Of The Moon Motion Effects On Our Vision
