What galaxies does Halley s Comet pass through?

First of all, the solar system cannot be counted as a galaxy, just a celestial system. The only galaxy is the Milky Way.

If nothing else, Halley's Comet will stay in the solar system for the rest of its life. Don't think that the solar system is just a place like the eight planets, and everything that the sun can control is the solar system. This range can be extended to 60,000 AU, while Neptune's orbital radius is only 30 AU.

From this point of view, the eight planets are "shrunk together" in the solar system.

Halley's comet aphelion is 35 AU, which means that Halley's comet is only 35 AU at its farthest from the Sun, which is much smaller than 60,000, so of course it is still in the solar system. Unless there is a special reason for it to change its orbit, it will end up in the solar system.

The Solar System Comets are all within the Solar System...

If you want to talk about the constellations that Halley's Comet passed in the sky as it approached the Earth?..Halley's Comet is a comet that orbits the sun with a 76-year cycle, and was first discovered by Halley. That's why it's called Halley's Comet.

Passing by Earth in 1986. Then 76 years later will come back and pass through the earth. I can still see.

As a result, it does not travel between galaxies. It's hard to travel between galaxies. If it's passing by the Earth visually, passing by those constellations.

This should be uncertain. .

Halley's Comet is a celestial body within the solar system and does not pass through any galaxy. 76 years is not a long time for a comet. If you want to know what constellations Halley's Comet might pass through when it returns, then you need knowledge of spherical astronomy and celestial mechanics.

Halley's Comet does not pass through other galaxies.

It only moves in the solar system.

Halley's Comet motion cycle is 75-76 years.

Its perihelion is within the orbit of Venus, and its aphelion is near the orbit of Neptune.

It doesn't leave the solar system.

You may think that the solar system is small, but this is a complete misconception.

At the speed of Halley's Comet, it is enough for it to travel for 76 years.

LZ got it?

It's in the solar system, and it's nowhere else.

Only the Milky Way really passed, over.

But the projection on the celestial sphere really needs to be checked.

Problem description: How many years does it take to orbit the Earth?

Analysis: In ancient times, people thought that the appearance of comets was a bad omen, until the 17th century, when the British astronomer Halley began to calculate the orbits of comets, he found that the comets that appeared in 1682, 1607 and 1531 had similar orbits, and he judged that these three comets were actually the same comet, and predicted that it would appear again at the end of 1758 or early 1759. In 1759, the comet appeared.

Although Halley had died in 1742, the comet was called "Halley's Comet" in his honor.

Halley's comet has a return period of 76 years, with the most recent return in 1986.

The most famous comet in history is Halley's Comet. The current comet is crowned with the name of the person who first observed it, such as Comet Hale-Popper, and Halley's Comet is the star that was predicted.

Newton's Principia Mathematica of Natural Philosophy, published in 1686, hypothesized that some comets had closed orbits, i.e., would recur regularly; Halley wanted to test this hypothesis.

From 1695 onwards, he collected past observations, analyzed them using Newton's laws of motion, and found that the orbit of the comet observed in 1682 was very similar, and it should be the same comet. If this speculation is correct, then it should have reappeared in 1758, when Halley predicted the appearance of a comet for the first time in 1705, saying: If he did reappear in 1758, future generations will remember that the credit for the discovery of the comet was attributed to an Englishman.

He was right, on Christmas Day 1758 (which also happened to be Newton's birthday, what a beautiful coincidence), it reappeared in the eyes of the world, a little later than Halley**, and passed perihelion on March 14, 1759. Later, this most legendary comet, sure enough, took the name of this Englishman and is still used today.

The Halley's Comet is known to everyone as its famous 76-year cycle. However, if you think that as long as you know the year in which Halley's Comet returned, plus 76 years will be the year of its next return, you are not necessarily right. Due to the small mass of a comet, it is difficult to travel when it passes through larger planets such as:

Jupiter) is susceptible to the gravitational pull of the planet and changes its orbit; In addition, every time you pass near the Sun, you lose mass when exposed to the Sun, which also affects your orbit. Scientists speculate that Halley's comet has a cycle of about years to years. However, compared to other comets, Halley's Comet is still a very active and periodically stable comet.

Halley's Comet visited again in 1986, the first time that mankind entered the space age, and the Soviet Union, Japan, and the European Space Agency all sent spacecraft to greet it, and interestingly, NASA was absent from this event! Of these spacecraft, the European Space Agency's Giotto was the closest, and the nucleus was also photographed. The next Halley's Comet will visit again in 2061.
