Scientists Determined That Titan Is Drifting Away From Saturn Hundred Times Faster Than Their Estimation



Scientists at the US Space Agency NASA and the Italian Space Agency have claimed that Saturn's moon (Titan) is moving away from it a hundred times faster than previously estimated. If this speed continues to increase like this, it will have an impact on Saturn's planetary system as well as the solar system.

According to the study published in the journal Nature Astronomy, besides Saturn, the Earth's moon is also drifting about 1.5 inches away from the Earth every year. But Titan's speed of drifting away from his planet has increased significantly. This is due to the Moon's gravity on the planet, creating a temporary bulge in the planet, and the energy it produces pushes the Moon further away. According to NASA, the drifting rate of Titan is equal to about four inches every year. Let us tell you that Saturn is the only planet in which rivers and lakes exist like Earth. Saturn has more than 80 moons, of which Titan is the largest.

The theory of Valery Lanie, assistant professor at the California Institute of Technology, states that both the inner and outer moons of the planets are distant at similar rates. Both types of moons get trapped in orbits due to the wavering of the planets, due to which they are pushed away. This theory has also changed the long-held belief that the outer moon moves much more slowly than the inner moon.'

How Far Is Titan Drifting?

Astronomers got this information from data from NASA's Cassini spacecraft. According to this, now Titan is drifting away from the Saturn at the rate of 11 centimeters per year, it takes a small speed to see, but it is slowly drifting away from Saturn. The planets drift very slowly in case of drifting away from the Sun. At the same time, the moons of many planets are also moving away from their planets. This process is called tidal acceleration.

Many questions can be answered. Research The results of this study have been published in Nature Astronomy. One can get answers to many old questions related to Saturn. So far, scientists know about Saturn that it was formed 4.6 billion years ago, at the time of the formation of the solar system, but they could not know how and when the system of the ring on Saturn and its 80 natural satellites formed.

Was Titan Already Drifting Away?

Titan is currently 1.2 million kilometers away from Saturn. It is not surprising to drifting away from Saturn. But scientists are seeing it is drifting away faster than expected, about 100 times more. This new rate has revealed that Titan was closer to Saturn than previously thought. That is, the whole system spread faster than it was thought. It has also been proved that till now there was something wrong in understanding tide acceleration.

Why Moon Drifts Away?

Tidal friction is another process related to Tidal Acceleration, it can also be understood by looking at the Earth. Due to the gravitational power of the moon, tidal ebb activity is seen in our oceans. Due to this power, the earth swells and regains its shape. But due to this, the moon gets lightened by the gravity of the earth and the speed of its orbit increases. With this extra energy, the moon is slowly drifting away from us. This speed is 3.82 centimeters per year. The same is happening with Saturn's Titan as well.

Mistake In Estimation

But scientists thought that this would not be much in the case of Titan. This is because they thought that Saturn is a gaseous planet and the sea and lake will cause more friction. But they proved to be wrong. It was then estimated that Titan is drifting away only 0.1 centimeters per year from Saturn. But now it is clear that it is going away at the rate of 11 cm per year.

The exact figures for Cassini gave this new information. Two techniques were used in this regard. One is astrometry and the other is radiometry. These two techniques confirmed the true speed of Titan's exit from Cassini's data.

What Will Be The Effect?

The moon's orbit will become very large after the next 50 billion years due to the moon's constant separation from its planets and after a while, it will stop expanding. If we talk about the Earth, it will take several days for the Moon to revolve around the Earth and take around on its earth. This will also affect the time of day and night and both will not have any effect on each other like a tidal ebb and then the moon will stop drifting away from the earth.

Initially, it was five hours a day: Scientists believe that when the moon was formed, there used to be only a day of five hours on Earth. Due to the moon itself, after 4.5 billion years, one day of the earth has been found to be 24 hours long. According to scientists, if there had not been a collision with one heavenly body to the Earth 4.5 billion years ago, there would have been no moon of the Earth.
