Periodic comet attracted by the Sun, sent to him, but pass due to the same sensitivity to the solar wind, which causes the surrounding cloud of dust and gases blown away from the Sun. People believe that the tiny particles of solar wind will impact more than large particles, but this assumption is wrong. If this were so, then how to explain the continued existence of the Asteroid Belt, which includes debris of any size is not affected, apparently, by the solar wind. The small object may lose velocity faster than the larger object because of differences in gravity, but if they are sensitive to solar wind, it occurs the same effect, – they are repelled equally. The comet, which (eventually) reach the Sun, with a very repeatable trajectory around the Sun, losing a lot of water vapor so that the ratio of substances in their composition is aligned at the expense of pushing away by the solar wind. In short, they lose their cover. They fly up with acceleration from the external space, but at this time do not change direction, going outside, and face (with the Sun). In fact, comets complete their orbits, coming nearer in the process, getting closer and closer to the Sun.
If there is a repulsive force, as the solar wind blowing against the comet, after you approach, it turns out, and since its speed when entering Salaciousjester increased, it again changes course. Increasing the speed of the comets allows them to move forward, despite some sensitivity to the solar wind. So they quickly fly around the Sun, keeping him at a distance, if have, essentially, an adverse impact from the wind, against which they can continue to move closer.
The solar wind is uniform, when approaching the Sun per unit distance, its influence increases by the same amount. Distance, which supports the comet, is not explained by such analogies as a car colliding with a brick wall, or a diver entering the water, or even man walking in a hurricane. The comet drifted to the side as we approach, going in the direction of least pressure, the least resistance (for a given direction of its movement – approx. transl .), while she still tends to the Sun. The position of each point of the trajectory, where this equilibrium is achieved, depends on the speed of the comet, which is constantly increasing – the more, the closer it gets to the Sun, and also increases the intensity of the impact of the solar wind. At each point of the orbit act these defining values. When the comet is in the outer space, its speed is relatively uniform, and so it smoothly slides to the side, not coming directly toward the Sun. When it enters your Solar System, the reverse speed overcomes the pressure of the solar wind, so the movement of the comet to the Sun is bent, but these two factors are always in effect.
It is obvious that some comets are periodic, since they regularly, after a certain number of years, appear again, approaching from the same direction, make a turn within the Solar system in the same place, leave the Solar System in the same direction and have the same predictable views. But the comet, which have great period, were registered in the past in a way that leaves a lot of uncertainty. If astronomers at the Millennium believed that the Sun is flying in an orbit around the Earth, then how accurate can their records be? And how do you know that it returns the previous comet, even if it is coming from the same direction? Is it possible that the same trajectory of passage through the Solar System has more than one comet? People have only recently left behind the Dark ages of the middle ages, and if they were sincere, would admit that they’re guessing. Did these comets observed? Do they have an accurate basis for comparison? As they conclude on a pencil sketch made by someone in the old days?
People think that if humanity discovers comets as they appear in that direction, declaring themselves even when they are destitute gases, because they are just entering the Solar System, scientists know of humanity . where was the comet, and know what was its orbit. They don’t know. They can’t find these tiny dark spots when they are flying in outer space. When scientists catch them from the light, in the orbits of comets already taken into account their sensitivity to the solar wind. This curve really starts outside the Solar System, this fact is known to the astronomers.
People think that the comet’s orbit is maintained by inertia. Of all the factors affecting a tiny comet that approaches the Sun, this force of inertia is not dominant. Any child who will throw a ball and watch it fall to the Ground when it moves along its trajectory, can feel. Arrow take that into consideration when you try to hit your target, aiming slightly above a straight trajectory to account for the drop. Inertia is the result . and not the cause. What causes the impulse, if not gravity. The ball thrown in space, where there are no gravitational influences that will still fly fast, but the gravitational pull acting from behind the trajectory, it will slow down. When the comet leaves your Solar System, it is directed into the distance, essentially in a straight line. Gravity acting behind the comet, slows it down, and so the pulse disappears.
People see comets only orbit that is essentially the end result or at least the part of the orbit, which includes the gravity of the Sun. The position of the tiny comet – dark, until it will enter the Solar System where the comet flares up under the influence of the Sun, cannot be determined by people at the time when it is in external space. They believe that when the comet is flying in the outer space, the orbit is wider or at least as vast as it seems, when the comet becomes visible. This is not so. As we explained in details the process of logging the 12th Planet in the Solar System, comets tend to the Sun, and if they are influenced by any factor which you submitted to the other side of the Sun, then adjust its orbit in this side. Further, because they are close to the Sun and tightened the grasp of the gravitational attraction of this giant, then accelerated, increasing the speed allows them to come closer. People only see that part of the orbit where the initial adjustment of parameters existing in the direction from the Sun, has already happened. They can see only half image.
Human the claim that long orbit can be determined on the basis of the inlet angle of the parabolic curve, is, therefore, absurd. Some comets with a large period are a few tricks, some only one. As the little man, peering with planet, he can’t leave, so you can look out beyond the Solar System, which he never left, how many tricks has this or that comet? Since the parabola and the ellipse is flattened even, essentially, in a straight line, how can they know how far this goes straight line before will be a reversal? For him to know. This can only guess .
