Introduction: In order to express my thoughts in a comprehensible way, I decided to use a few of my own images, along with the essential images and descriptions of the “great ones”, always citing the authors of the said pictures and descriptions, whom I would hereby like to offer my most sincere gratitude!
The science of astronomy deals with many new things today, new discoveries, new theories, thoughts are emerging and waiting to be resolved. Such an interesting idea has just occurred to me, something that scientists have not been paying attention to. My idea is related to solar wind. Solar wind is generated by the Sun’s nuclear fusion reactor converting hydrogen into helium, producing at the same time lots of other particles too, but predominantly light. This light can hardly getting out of the Sun, but once being outside, it spreads spherically in the Universe at the speed of light. We are primarily interested in the effects of the solar wind on the planets around the sun. Since it is known some significant results have already been achieved in accelerating spacecraft using the light and radiation energy generated by the Sun. The effect of solar wind is utilised in accelerating space installations with the help of solar sails, but then, such a solar sail is the Earth too, having been blown – pushed away energy from the Sun – by solar wind, for billions of years. And this pushing force is reduced by the mutual gravitational attraction of the Sun and the Planets. Each and every visible star in the Universe has its own "solar wind" and this "solar wind" affects the celestial bodies around and beyond. This is being counteracted by gravity.
This long lasting light pressure, being affected a large surface of our planet, cannot be neglected in calculating Earth's orbit data and orbital motion. Arise it too, this light pressure affects not only the Earth but its companion, the Moon as well. Indeed, even the distance between Earth and Moon varies, depending on their angle relative to the Sun, as it is affected by the relative positions of the three factors, that is, the Sun, the Earth and the Moon. I have so far been considering the certainly existing effects of the light pressure caused by the solar wind, but of course no planet or even the Solar System is unaffected by this. Another question, arising nowadays, that astronomical scientists have been studying and discussing about the possible existence of a ninth planet. I think possible the solar wind’s light pressure may be causing some peculiar changes in the Solar System.
