Is it true that comets orbit the solar system for 60 years? What is the scientific basis for this?

Have time to read my article "How Are Galaxies Formed?" The Relationship between the Earth's Ice Age and the Sun's Position in the Milky Way, ......Look"A jasper orchid chasing stars in Lingjing Lake"Can.

Yes, NASA's WISE spacecraft in the infrared band scans scientists have found that there are about seven times as many long-period comets at least miles in diameter as before.

It's true. Because scientific research has shown that comets are also affected by the forces of the solar system, it circles the solar system regularly.

It is true that the comet has circled the solar system for 60 years, because judging from the time record of the comet's several appearances, it is indeed 60 years, and at the current astronomical level, we already know the comet's trajectory, and its period has been determined.

Kepler thought there were as many comets in the sky as there were fish in the water.

Based on the number of comets orbiting between the Sun and Mercury, Arago came to the conclusion that Liang Xing had just passed.

There are 17 million comets in the solar system.

Lambert believes that there are 500 million comets in the interval of 1.456 billion kilometers from the Sun to Saturn.

It is also believed that there are 740 trillion comets in this range.

The reality is that no one knows exactly how many, because no one has counted. And I won't count them, but they must be very numerous. To illustrate this problem, we might as well borrow one from Kepler.

Metaphor: If a fisherman stands on the surface of the sun and fishes into space. A fishing rod will surely "catch" a comet.

Cruising, without certain rules, often leaves one gravitational sphere and enters another. They are in the sun.

Tie in and out. Some comets have never been seen on Earth at all, but they will suddenly appear on Earth.

and then it was gone, never to be seen.

Do comets that are active in the solar system have a fixed orbit that does not collide with each other and collide with the Earth? No. Their orbits are always changing due to external forces. This track can be accessed from.

Ellipse and becomes a parabola or hyperbola. Jupiter, for example, is the "expert" at interfering with comet orbitsAstronomers hair.

Now, it is always standing on the road to block the comet's path, exerting a powerful influence on these small celestial bodies. This is mainly due to:

Because of its gravitational pull is great.

The above is the basic situation of the comet "family", and its members are innumerable.

Through the data of multiple observations, we can deduce the elements of the comet's orbit around the sun, that is, perihelion, perihelion, eccentricity, the inclination angle of the orbit facing the ecliptic plane, the ecliptic longitude of the ascending node (the point on the ecliptic plane from south to north in the orbit), the angular distance between the perihelion and the ascending node, and then the comet's ephemeritis, that is, the apparent position on the celestial sphere at different times (right ascension and declination).Many comets have oblong-oval orbits, parabolic seeps, and even hyperbolas. Obviously, comets moving in parabolic or hyperbolic orbits are non-periodic comets, and they will never return and flee the solar system, so are they really members of the solar system?

In fact, these comets are observed before and after perihelion, and their anastomotic orbits are calculated, and during this period of time, the difference between the three orbits is small, and the observation accuracy is not enough to lead to the calculated orbit error, and the more important thing is that the liquid hail in the comet's operation is affected by the gravitational perturbation of large planets and other orbital changes, and most comets are still oblongated ellipticals with eccentricity slightly less than 1 after correcting these influences, so they are members of the solar system, and a few comets will never return. Even if the comet with a very oblate and long elliptical orbit has a very long orbital period, it takes hundreds or even tens of thousands of years to return to the solar system once, in the history of human civilization, only short-period comets (orbital period less than 200 years) have been observed many times, the vast majority of short-period comets are forward-orbiting (that is, the same as the direction of rotation of the planets), the inclination angle of their orbital plane relative to the ecliptic plane is less than 45 degrees, and a few (such as Halley's Comet) reverse orbital, while the inclination angle of the orbital plane of long-period comets and non-periodic comets is randomly distributed, there are many forward and reverse revolutions.

In the "Oort Cloud", the outermost group of celestial bodies in the solar system, it is speculated to be a huge comet with a diameter of 155 kilometers".c/2014un271

Now, 3.5 million years later, the sun is approaching.

Comet Bernardineli Bernstine (The mass is 1,000 times heavier than that of the average comet, and it is larger than the largest known comet, Salabad (C 1729p1), with a diameter of 155 km.

Comet Bernardineli Bernstine (It is moving towards the Sun from an aphelion of 40,400 AU (astronomical unit: about trillion kilometers).

As of August 2014, the mathematical distance from the Sun was 29 AU (about 100 million kilometers), which decreased to about 100 million kilometers by May 2021). It is expected to reach perihelion, the closest point to the Sun, in 2031, slightly farther from Saturn's orbit, about 100 million astronomical units (about 100 million kilometers). It is closer to the Sun than it was 3.5 million years ago when it passed perihelion, 18au (about 2.7 billion kilometers).

Comet Bernardineli Bernstine (The continuous observations are expected to help elucidate the formation of the "Oort Cloud" and the Solar System, which is considered the best observation opportunity around the outer part of the Solar System.

Unlike asteroids, they don't know if they exist until they get close to Earth. And the relative velocity of the comet is also very large. Although this time it is in the orbit of Saturn, there is a possibility that one day such a massive comet will collide with the Earth, and it is not that it is not impossible.

It is conceivable that if the comet, after a certain circular flight, happens to collide with the earth, then the earth's crust will be knocked into the universe, and then the hot rock vapor will cover the entire surface, and the life on the earth will be wiped out in an instant. Of course, everything including life deep underground.

Planets are artificially named, and if the moon revolves around the sun, then the moon is a planet. First of all, the revolution is relative, the earth revolves around the sun, and the sun also rotates due to the gravitational pull of the earth on it, but because the sun is much more massive, the point around which it revolves is inside the sun, and at a very close point to the center of gravity, we can't see that it is rotating. And the mass of the Earth is larger than that of the Moon, so we can't see the rotation of the Earth due to the gravitational pull of the Moon, but if two celestial bodies have about the same mass, they will revolve around a certain point, and if this point is not inside any of them, then they are binary stars, such as Pluto and its moons, which are now two "dwarf planets" and are binary stars of each other.

So if a planet orbits a planet, then this planet is the moon of the planet it orbits, and if the planet is massive enough, then it and the planet that is orbiting are double stars.

Black holes don't revolve around the sun, they kill people.

First, a star like the Sun has a much smaller mass than a black hole, and it only takes its turn to revolve around the black hole, and secondly, if the black hole is less massive, then it will become a binary star with a star, such as a binary star system in the constellation Perseus (we can only see one of them) because the black hole is a star and has a mass comparable to that of a star. However, when a black hole is a supermassive star or a supermassive black hole formed by the merger of several black holes, it will roll away its binary partner and engulf it, releasing gravitational waves at the same time, thereby cleaning all the matter around it, and the star can only orbit on a farther scale. In this way, it will not follow the sun, 9, no, because the mass of the black hole is more than three times that of the sun, so only the sun revolves around the black hole.

1, no! ,1,No, because a black hole is a celestial body with the contraction and compression of the inner core of a star, and the mass of the black hole is much greater than that of the sun, and the universe is conclusive, only the small mass of the celestial body revolves around the large mass object. It is impossible to do it the other way around.

A black hole the size of a moon could pull the entire solar system into it. The mass of the entire solar system is inferior to that of a black hole the size of a moon. ,0,

3. Comets have always been a mystery. The last point is that the comet has always been a mystery, it only rotates around a certain area, and it does not occupy any influence. So we'll know more about the research of the comet, but as long as time passes, we can always find out the mystery.

The idea that comets orbit the solar system for 60 years is based on the observations made by astronomers through images and telescopes from satellites sent out for study.

There are many peculiar phenomena in the universe that can only be obtained through the practice of science or theory. After all, science can be proven by practice. Not to mention the theory of the theory of the universe, which requires theoretical derivation, but nowadays, limited to human science, we can only come up with certain hypotheses, and then we can discover this phenomenon through subsequent theoretical practice.

Is it really wrong? The comet then orbits the solar system for 60 years. Is there some scientific basis for this?

The answer is yes. There are several reasons for this.

There is scientific evidence, for example, Halley's Comet circled the solar system for 60 years, but mankind discovered the existence of comets relatively late, and there was no technology at that time. Current science and technology are enough to prove this point.

Glad to answer for the landlord.

Planets can revolve around planets.

It is impossible for a black hole to revolve around the sun.

But because the black hole is tens of thousands of sails larger than the Sun, it is hundreds of millions of times larger.

So the gravitational pull is much greater than that of the sun.

We know that too.

The nine major states of the solar system orbit the Sun because the Sun's gravitational pull binds us.

If the mass of the earth's liquid spring is greater than that of the sun.

Then the gravitational pull of the earth is greater than that of the sun.

The eight planets will revolve around the Earth. Thank you.

Comets do not revolve around the Earth.

Almost all comets revolve around the sun, and their periods, that is, the time it takes to make a circle, vary from comet to comet, and the famous Halley's comet has a cycle of about 76 years, and there should be a cycle of several hundred years.

The reason why I say this is almost because some comets may be captured by nearby planets when they orbit the sun, and may become satellites of planets, or be torn apart and fall, the latter is a typical example of the "Shoemaker-Levi-9" comet in 1994 when it passed near Jupiter, was captured by Jupiter's gravity, and was torn into more than 20 pieces by Jupiter's gravity, and finally fell into Jupiter.
