Why do the planets of our solar system orbit the Sun in an inclined plane?
The moon is orbiting in a five-degree inclined plane from the orbital plane of the earth around the Sun.
There is no explanation till date why the moon is orbiting the earth in a such a five-degree inclined plane.
The reason for the moon orbiting the earth in a five-degree inclined plane is that, when the moon is orbiting the earth, while the earth is revolving around the Sun, it is following the Sun which travels in the space at a speed of twenty kilometres per second.
This means that when the Sun is moving forward in the space, all the planets orbit around the Sun in an upward-downward movement.
Even though the planets travelling in a vertical path from the direction in which the Sun is travelling, they are not orbiting the Sun in a ninety-degree angle. On the contrary, they are actually orbiting the Sun in a sixty-two-degree angle.
The plane in which the planets orbit around the sun in such a way is called ecliptic plane.
This is because, eclipses occur due to the passing of certain planets of the inner circle between the Sun and the planets of the outer circle.
However, all the planets do not orbit in this common axis, but orbit with a deviation of one or two degrees.
For example, Mercury which is closer to the Sun, orbits around the Sun in a seven-degree inclination from this common plane.
Similarly, Pluto, the farthest planet from the Sun, is orbiting around the Sun in a seventeen-degree inclination from this common plane.
Eris, a dwarf planet which is even farther away from Pluto, is orbiting around the Sun in a forty-four-degree inclination from this common plane.
The Sun traveling in the space at a speed of twenty kilometres per second is the reason for the planets orbiting the Sun in an inclined plane.
This means that the planets orbiting the Sun in an upward to downward direction,at the same time the Sun is moving forward. This in turn forces the planets to chase the Sun to revolve around it thereby resulting in the inclination of the orbital plane of the planets.
This can be effectively reiterated by an imaginary illustration.
Imagine a giant-sized yellow balloon in the sky.
Visualize some crows circling around it in an upward-downward motion.
In this situation, imagine that the giant yellow balloon is beginning to drift forward.
At this point, the crows which were circling the yellow giant balloon will be forced to follow the balloon to circle it. This will result in a minor inclination and extension in the circular path of the crows.
Likewise, the orbital path of the planets revolving around the Sun, which is traveling forward, will also become inclined and elliptical.
At this juncture, also think of a sparrow circling one of those imaginary crows in an upward-downward direction.
You can very well say that the circular path of the sparrow will also become elliptical and inclined.
In the same manner, when the circular path of the earth which is orbiting the Sun in an upward-downward direction changes to an inclined and elliptical path, the circular path of the moon which is orbiting the earth in an upward-downward direction also becomes inclined and elliptical.

How are planets formed?
It is believed that planets were formed when the gigantic clouds of dust found in the space rotated, the dense area in the center became the Sun and the dust clouds in the edges gathered to form the other planets.
At this point, the scientists discovered three minor planets orbiting very close to a pulsar star PSR 1257+12 which is 2300 light years away from the earth and radiates extreme heat several times more than that of the Sun.
It is surmised that the reason for these three minor planets still orbiting without getting evaporated is that their outer crust must have been made of diamond .
However, how could diamond form in the void of the outer space?
The formation of diamond as big as the size of a planet is possible only in the presence of an enormous amount of carbon and a condition which could cause immense pressure to enable that carbon to form into diamond.
But, how is this possible in the empty void of the outer space?
At this juncture, the British scientists discovered inside a dead star in the space, a formation of a large diamond crystal core which was even massive than the moon in its size.This star was named as BPM 37093.
Already many stars close to these stars have been found evaporating.
It is impossible for such a massive diamond crystal to form in the empty void of the outer space.
But, not only a massive amount of carbon and but also the gas that is required to create tremendous pressure to convert that carbon into diamond is present inside the stars.
This is the reason for the formation of a diamond crystal, which is larger than the moon, inside a dead star.
At this point, because a radiating dead star, which emitted more heat than that is being emitted by the Sun, attracted the dead star which had formed the moon sized diamond , the gases found in the outer part of the dead star evaporated and the moon sized diamond alone which had formed at the core of that dead star now orbiting around the pulsar star.

In search of planet nine.....
It is a common belief that all planets, including the Sun, were formed some forty-five million years ago, from a circumstellar disk of dust which was rotating in the outer space.
It is a common belief that all planets, including the Sun, were formed some forty-five million years ago, from a circumstellar disk of dust which was rotating in the outer space.
It is believed, in particular, that Sun came into being from the massive centre part of the disk of dust and other planets were formed when the flat periphery of the disk accumulated here and there.
On the basis of this theory, it was generally expected that all the other planets should be revolving around the Sun in the same plane in which the Sun is rotating in its axis.
At this point, it was discovered that the Sun was rotating with a six-degree inclination.
But, Professor Dr. Konstantin Batygin, Dr. Michael Brown and their under-graduate student Ms. Elizabeth Bailey offered a new theory that the Sun is not six-degree inclined, but on the contrary, only the orbital plane of the other planets is inclined to the extent of six degrees.
However, the fact remains that all the planets are orbiting the Sun at different angles.
Dr. Michael Brown states that the gravitational force of a yet-to-be-discovered planet which is orbiting the Sun on the outer rim of the solar system, even farther away from Pluto, is the reason for the planets revolving around the Sun in an inclined plane.
Particularly, this planet, which is called “planet nine”, is believed to be four times larger than the earth and at the same time weigh ten times more than the earth itself. This has been estimated by computer models created by Dr. Michael’s team.
Moreover, Dr. Michael has said that the orbital path of this planet would have inclined from the orbital plane of the other planets and set at an angle of thirty degrees.
To sum up, as per the Disk of Dust Theory, it is considered that there is absolutely no possibility of the formation of a large planet beyond Neptune.
To sum up, as per the Disk of Dust Theory, it is considered that there is absolutely no possibility of the formation of a large planet beyond Neptune.
Thus, when a question arose as to how planet nine came into being in the far outer Solar System, Dr. Michael suggested that it might have been formed at the inner regeion of the Solar System and later ejected to its present location by Jupiter.
Again, when a question was raised as to how a planet that is ten times heavier than the earth could curve the orbital path of the other planets, especially when Jupiter is three hundred times and Saturn is ninety-five times heavier than the earth, Dr. Michael Brown offered an explanation that since the orbital path of the planet in question is very big, it is able to curve the orbital plane of the other planets.
At this juncture, six minor planets, similar to Pluto, were discovered beyond Neptune.
Moreover, it has been found out through the computers that the orbital path of these minor planets was also set at a thirty-degree angle from the common orbital plane of the other planets.
Dr. Michael Brown has reiterated that the gravitational force of Planet Nine is the reason for the orbital path of these minor planets being set at a thirty-degree angle from the common orbital plane of the other planets.
Similarly, Scott S. Sheppard of the University of Carnegie, Washington, discovered a minor planet which was orbiting the Sun even farther away from Neptune.
Scott S. Sheppard suggested that the gravitational force of Planet Nine was the reason for the orbital path of this minor planet being inclined.
On the basis of this finding, he expressed his hope of the existence of Planet Nine with a ninety-percent probability.
While expressing his opinion about this theory, J.J. Kavelaars, a scientist in the astronomical research centre of Canada, has stated that there is only one percent possibility for the existence of Planet Nine.
In a desperate look out for Planet Nine, Dr. Michael Brown and Dr.Sheppard along with their teams searched with the state-of-the-art telescopes in the direction where this planet is believed to be existing.
But, despite searching in a very vast area, the planet could not be discovered.
However, Dr. Michael Brown has expressed hope that there is still a ten-percent possibility for discovering this evasive planet.
Why the orbital path of the minor planets is more inclined from that of the other planets?
I had already stated that the forward movement of the Sun is the main reason for the tilt in the orbital path of the planets revolving around the Sun in a sixty-degree angle.
I had also explained with an illustration that if crows (planets) start circling a giant-sized yellow balloon (Sun) moving slowly in the sky, in an upward-downward motion, the circling path of the crows (planets) will be inclined towards the direction in which the balloon (Sun) moves.
At this point, in case some crows circle the same yellow balloon from a long distance in a circular path, how would the circular path of these crows be?
The circular path of these crows will be highly elongated and will be more deviated from the circling plane of the inner ring crows.
In a similar way, the orbiting path of the minor planets revolving around the Sun from a long distance will be more deviated from the orbiting plane of the other inner planets.
Scientists firmly believed that a planet with a size similar to that of Neptune, existed at the periphery of the Solar System.
However, a study conducted in March, 2014 with NASA’s Infra-Red Rays Telescope, ruled out the existence of such a planet.
NASA has declared that there is absolutely no possibility of such a planet existing at a distance of ten thousand astronomical units (one astronomical unit is the distance between the Sun and the earth, i.e., one hundred and fifty million kilometres) from the Sun, that is similar to the size of Saturn which is ninety-five times larger than the earth.
Similarly, NASA has also declared that no planet similar to the size of Jupiter, i.e., three hundred and eighteen times larger than the earth, exists at a distance of twenty-six thousand astronomical units from the Sun.
''But there is a possibility that Planet Nine doesn't exist and that some other explanation accounts for the motion of objects that astronomers observe in the Kuiper Belt. Whatever the outcome, Green said, the general public will have "a front row seat" for the show-Jim Green Director of Planetary Science - NASA
