Do all planets revolve around the same? What are the reasons for its rotation? We will answer these questions in this article.
“It depends on the meaning of the rotation,” says Hilary Shaw. “A planet orbiting a full circle is the most complete revolution around its star for an outside observer. Finding a planet that doesn’t rotate is difficult, as a planet usually orbits in the opposite direction to its star for a period of a day equal to its year.” ».
“We have two planets that don’t orbit in the solar system, but what is the probability that a planet’s day is exactly the same as its year?” Hillary added. There are a lot of planets that apply to this. High temperatures and long days and nights will prevent life on this planet, as the sun and other planets move very slowly in the sky while the stars are stationary.”
Mike Falls noted that: “Normally planets rotate, but the universe contains billions of stars, a number of which must stop rotating, as the solar system or star consists of clouds of gas, and in the event that this cloud does not have angular thrust, it will not rotate. The result is a star that does not revolve around the planet.
The molecular cloud is not observed, but it has an angular thrust. Maintaining this strength means that this cloud rotates more quickly as it collapses; As some of this gas collapses into the sun’s disk, a ring of material acts as an incubator for the planets that rotate spontaneously.
For example, if we look at the Earth from above the ecliptic (an imaginary plane corresponding to the solar disk of the solar system); The Earth will rotate counterclockwise, which is the same direction as the Sun’s rotation.
Venus rotates clockwise and counterclockwise, eventually Venus will be in the orbit of the Sun, like the Moon in the orbit of the Earth. This means that the orbital period is equal to its rotation around itself.
Eventually Venus will meet the Sun at all times and the planet’s day will be equal to its year; Because the direction of rotation and orbit are different; The planet Venus will almost no rotation around the fixed stars.
The sun will appear to move across the sky when looking from the surface of a planet that does not rotate and the other stars will be stationary, however, Venus is still rotating a little with a period of approximately 235 million years, because our solar system revolves around the center of the Milky Way at that time, and by interactions and collisions with other bodies In our solar system some planets have been hit and lost their rotation.
“Planets arise as dust particles that are attracted to each other by static electricity, and once they have enough mass they will attract other masses, and when the particles collide with the growing asteroids, they may collide with their center of gravity, and then the force of the particles is transformed into an angular thrust that contributes to the mass of the planet,” said John Hockday.
He added: “All the particles, pebbles, rocky asteroids and comets provide more angular thrust and contribute to the growth of the planet, and it is difficult for the debris to collide with the asteroid directly at the center of gravity; So all the planets will revolve.”
The slowing down of the Earth’s rotation may be the reason for the presence of oxygen!
