Earth is moving away from the sun, like all planets




<div> </ div> <div class =

The Earth, moving in its orbit around the Sun and spinning around its axis, seems to make a closed, unchangeable, elliptical orbit. However, if we look at high enough precision, we will discover that our planet is actually spiraling away from the sun.Larry McNish, RASC Calgary

At & nbsp; January 3, 2019 The Earth reached the point in its orbit where it is closest to the Sun: perihel. Each object that circles around a mass (like our Sun) is a real ellipse, which contains the closest approach point that is unique to that particular orbit, known as periapsis. In the last 4.5 billion years the Earth circled the Sun in the ellipsis, as did all the other planets circling its stars in all the other mature solar systems in the galaxy and the universe.

But there is something you can not expect or appreciate to happen: Earth's orbital paths do not remain the same over time, but spirally outward. This year, in 2019, our perihel was 1.5 centimeters further than last year, which was more distant than last year, etc. It is neither the Earth nor the Earth; every planet is moving away from its parenting star. Here's the science why.

The exact model of how the planet spins around the Sun, which then moves through the galaxy in the other direction of movement. Keep in mind that all planets are in the same plane and do not wander behind the sun or create any kind of light. Their orbits are elips that seem to be constant over time, but if we could measure them accurately, we would see mild deviations from closed, unchanging orbits.Rhys Taylor

The force responsible for the orbit of each planet around every solar system in the universe is the same: the universal law of gravitation. Regardless of whether you look at it in the sense of Newton, where each mass attracts every other mass in the universe, or in the sense of Einstein, where mass and energy curve the space-time fabric through which other masses travel, the greatest mass dominates the orbit of everything that affects it.

If the central mass was unchangeable and were the only factor in the game, the gravitational force would remain constant over time. Each orbit would have continued forever in a perfect, sealed ellipse, and it would never have changed.

In Newton's theory of gravity, orbits make perfect ellipses when they appear around individual masses. However, in General Relativity, there is an additional pre-emptive effect due to space-time curvature, which causes the movement of orbits over time, in a manner that is sometimes measurable. Iron precision at a rate of 43 "(where 1" 1 / 3600th degree) per century; a smaller black hole in the OJ 287 at a speed of 39 degrees on a 12-year orbit.NCSA, UCLA / Keck, A. Ghez Group; Visualization: S. Levy and R. Patterson / UIUC

Of course, this is not happening. In every solar system there are other masses: planets, satellites, asteroids, centaurs, Kuiper bays, satellites and others. These masses are used to hinder the orbit, causing them to precess. This means that the point of approach – generally the periapsa or perihelium for the orbit in relation to our Sun – turns over time.

Orbital mechanics, in different ways, affects the precession of the equinox. The Earth, for example, had its perihel and December solstice aligned only 800 years ago, but slowly decay. With a period of 21,000 years, our perihelii preceeds in such a way that it changes not only the point of the closest approach in our orbit, but also the position of our polar stars.

Just 800 years ago, the perihel and the winter solstice were aligned. Because of the precession of Earth's orbit, they are slowly breaking down, completing a full cycle every 21,000 years.Greg Benson on the Joint Server

There are other factors that change our orbit, including:

  • additional curvature of space-time due to general relativity, which causes the planets near the masses to undergo additional precession,
  • the presence of particles of matter in the plane of the Solar System, which causes the withdrawal of the planet and creates an inspiring appearance,
  • and the creation of gravitational waves, which occurs when any mass (such as a planet) passes through an area that changes spatial-temporal curvature (such as near a star), also causes inspiration.

However, these last two effects are important only in extreme conditions, such as very close to a large, compact mass, or in the early stages of creating a solar system when protoplanet disks are present and are still massive.

Protostar IM Lup has a protoplanet disk around it that shows not only the rings but also the spiral shape towards the center. There is probably a very massive planet that causes these spiral traits, but it still needs to be definitely confirmed. In the early stages of the formation of the Solar System, these protoplanetic disks cause dynamic friction, causing the young planets to move the spirits rather than to complete the perfect, closed elapses.S. M. Andrews et al. and DSHARP co-operation, arXiv: 1812.04040

Today, the Earth (and all the planets) so far away from the Sun and surrounded by such a rare quantity of matter that the inspirational time period is trillion-quadrilateral times longer than the present era of the Universe. Since the protoplanet disk has completely disappeared about 4.5 billion years ago, there is almost nothing to disperse our angular momentum. The greatest effect that contributes to our inspirational solar wind, ie the Sun Particle, which strikes our planet and stick, causing us to lose a little angular momentum.

All in all, the Earth does not even spiral toward the Sun; it's spirally out, far away from it. Like all solar system planets. With every passing year, we find only – 1.5 centimeters, or 0.00000000001% of Earth and Sun distance – more distant from the Sun than the previous year.

The reason for this is because of the Sun itself.

This section shows different regions of the surface and the interior of the Sun, including the nucleus, where nuclear fusion takes place. As time passes, the area of ​​the core containing the helium expands and increases the maximum temperature, which causes an increase in solar energy.Wikimedia Commons by Kelvinsong

Deep inside the Sun is the process of nuclear fusion. Every second the Sun emits about 3,846 times; 1026 joule of energy, which are released by converting the mass into energy into the core. Einstein & nbsp;E = mc2 is a root cause, nuclear fusion is a process, and continuous solar energy output is the result. This energy is the fundamental process that starts practically every biologically interesting process that is happening on Earth.

But what is underestimated is that with time the transformation of matter into energy results in the loss of the Sun by a considerable amount of mass. During the history of the 4.5 billion years of the Solar System, our Sun lost about 0.03% of its original mass due to the nuclear fusion process: & nbsp; comparable to the mass of Saturn.

The planets of the Solar System, shown on the scale of their physical size, all orbit according to specific rules. As the Sun loses mass as it burns through its nuclear fuel, rules remain constant, but the orbits themselves change. In the history of the Solar System, our Sun lost 0.03% of its original mass: approximately the mass of Saturn.OUR

On an annual basis, the Sun loses about 4.7 million tons of matter, which reduces the gravitational attraction of each facility in our solar system. & Nbsp; This is the gravitational attraction that causes our orbits to behave the way they behave.

If the retraction remained unchanged, there would be very, very slow spiral internal spiral due to the effects of friction, collision and gravitational radiation. But with the changes we truly experience, the Earth, like all planets, is forced to slowly step away and spin outwardly from the sun. Although the effect is small, this change of 1.5 centimeters per year can easily be calculated and unambiguous.

The Lunohod-2 rover, which launched the Soviet Union and depicted here in 1973, contains a corner reflector (instrument number 6) used to reject the Earth's laser light to determine the distance from the moon. Centimeter accuracy can be obtained for the distance of the Earth and the Moon using this technique, but there is no such technique to measure the distance to the Sun with such accuracy.Sovfoto / UIG via Getty Images

However, we can not directly measure that distance change. We know it must happen; we know what must be his size; we know that we are leaving the Sun; We know this is happening to all the planets.

But what we would like to do is measure it directly as another test of the physical laws we know them. So physics progresses:

  • predicting what we expect to observe on the basis of the knowledge we have gathered and our best theories,
  • by conducting experiments / observations that measure the results of such a test on the required precision,
  • and compare what we see with what we expect.

When things are in agreement, our theories are confirmed; when it does not, it is a sign that we are at the height of the scientific revolution.

Observations using Atama's large millimeter / submilimeter string (ALMA) revealed an unexpected spiral structure in the material around the old R Sculptoris star. This feature has never been seen before and is probably caused by a hidden star that circulates around the star, which is one of the many unexpected scientific results that came from ALMA. In general, unexpected results can be predictors of new physics or physical systems and are often the most interesting results that nature can offer.ALMA (ESO / NAOJ / NRAO) / M. Maercker et al.

However, in the case of the Solar System, it would be a shock if the Earth and all the planets were not shaken by the sun. The story of why we have to separate ourselves from the Sun is so simple and convincing that it is impossible to ignore it.

The sun emits the energy we are observing, which allows us to calculate the rate of loss of mass through Einstein's E = mc2.

The Sun's mass, along with the orbital parameters of our planets, determines the way and shape of how they turn around the Sun.

If we change this mass, the orbit changes in an easily calculated amount, even using direct Newtonian physics.

And when we do these calculations, we find that the Earth is away from the Sun at about 1.5 centimeters per year.

When we put familiar objects in the rows of the solar system, four inner, rocky and four outer worlds stand out. However, every object circulating around the Sun spirally moves away from the massive center of our solar system because it burns through its fuel and loses its mass. Although we have not observed this migration directly, physical prediction is very clear.NASA is The Space Place

Losing the mass of the Sun by burning a nuclear fuel ensures that every mass circulating in our solar system is slowly spiraling outwardly. About 4.5 billion years ago our planet was about 50,000 kilometers closer to the Sun than it is today, and it is growing faster as the Sun continues to develop.

With every passing orbit, the planet becomes less tightly bound to our Sun. The speed with which the Sun burns through the fuel increases, accelerating the speed with which all the planets spiral out. Though this should never be undermined by any of the planets we have today, the slow, stable, external migration of every world is inevitable.

We are closer to the Sun this year than we ever will be. This also applies to every planet around every star in the universe, which gives us another reason to appreciate everything we have today.
