Mars is moving, and scientists have questions – BGR

  • Using data collected over 18 years of observations, scientists now say that the planet Mars is in motion.
  • As a result of wiggling the planet its poles move constantly.
  • Earth also has a wobble, but the Mars wobble is a little more mysterious than Earth because Mars doesn’t have oceans.

When you think of the planets in our solar system you might think of them just kind of spinning like peaks. They rarely orbit according to their orbital plane – the Earth, for example, spins at an angle of about 24 degrees – but most simple models of the solar system make it similar to planets spinning perfectly. Well, there are some that are not, and we discovered that Mars is one of those planets.

In a new paper published in Geophysical Research Letters, scientists claim, there is little movement on Mars. This means that its poles do not go up perfectly all the time, moving on a timeline of about 207 days. That makes Mars the second planet with a recognizable wiggle (called a Chandler wobble). First? Land.

Earth’s Chandler’s wobble has been known for some time now – it is named for Seth Carlo Chandler, the man who first discovered it back in 1891 – and there is still some mystery as to how and why it moves as it is. Mars, on the other hand, is even more mysterious, largely because of the things that the Red Planet does not have on Earth.

The origin of the Earth’s wobble is not fully understood, and theoretically, it should have settled down over time. However, the fact that the Earth contains so much water and thick air means that this imbalance can continue indefinitely. Mars, on the other hand, is very different.

Summary of the finding, by the authors:

For the first time for any solar system group but Earth, one part of Mars’ spinning axis movement on the surface of Mars, known as the Chandler wobble, has been discovered. The movement has a duration of 206.9 ± 0.5 days, a surface width of 10 cm, and is in an almost circular anticlockwise direction as seen from the North Pole. Pole movement is determined from radio monitoring on Mars Odyssey, Mars Reconnaissance Orbiter, and Mars Global Surveyor, in order of sensitivity reduction. The discovery of the Chandler wobble improves our understanding of energy distribution in the fitness for periods close to the moving time.

The movement found on Mars is quieter than Earth, but Mars also does not have moving surface water to sustain the movement. However, there is a feeling in Mars. It is much stronger than the weight of the Earth, but atmospheric pressure can help keep the tip going. However, it is likely to disappear completely, although it is difficult to say how long that would take.
