Flying out of the solar system or the Milky Way, last year s news. Like Apollo?

The Voyager 1 probe, launched in 1977, is headed towards the center of the Milky Way. It is not accurate to say that it flew out of the solar system, that is just NASA, that is, NASA, the clear extent of the solar system has not been clearly defined internationally, and now Voyager 1 is about 121 astronomical units away from the Earth, although it is outside the orbit of Pluto, but it is still within the range of the Coberie belt of 50 to 500 astronomical units, and if the Oort cloud is defined as the outermost layer of the solar system, it is even farther, and the Oort cloud is 50,000 to 100 meters from the sun. 000 astronomical units is almost 1 light-year away, and the gravitational pull of the Sun can be controlled to about 2 light-years.

There is an opinion that it did not fly out of the solar system at all, but only flew out of the sphere of influence of the solar wind, and it is still far from the boundary of the solar system, which is about 150 billion kilometers, while Voyager 1 only flew 19 billion kilometers.

It is Voyager 1. It has been determined that it has not yet flown out of the solar system,,, as it has indeed confirmed the influence of the solar wind.

In the solar system, it is unlikely that humans want to fly out of the Milky Way.

The Voyager 1 spacecraft flew out of the solar system.

Reports say that Voyager 1 flew out of the solar system.

Voyager One. Fly out of the solar system.

That's a detector. It is estimated that the man-made spacecraft has never even been to Mars.

The solar system, the Milky Way is too big.

It's just a flight out of the Teiper belt.

The report is about the solar system in the narrow sense, the senses of ordinary people.

At least you have to run out of the Ultra Nebula.

It is said that it has not flown out of the solar system until ......

Lonely Voyager One.

Where does the Sun of the Milky Way go: The Sun is located at the edge of the Milky Way, on the third spiral arm of the Milky Way, the Orion Spiral Arm.

The Milky Way is a barred spiral galaxy with a diameter of about 100,000 to 180,000 light-years and a thickness of 2,000 light-years on a thin stellar disk. The appearance of the Milky Way resembles a disk, with a raised nuclear sphere in the center and a radius of about 10,000 light-years. In the night sky of the Northern Hemisphere summer, the brightest part of the Milky Way is in the direction of the Silver Center.

The Milky Way has 4 spiral arms, namely the Shield-Centaur Arm, the Bottom-Centaur Arm, the Perseus Arm, and the Outer Rim Arm. The Solar System is located on the Orion Arm of the Milky Way, a small arm between the Perseus Arm and the Centaur Arm. The solar system orbits around the galactic center at a speed of about 220 kilometers per second, and it takes about 100 million years to make one circle.

The Sun's orbit around the Milky Way is roughly elliptical, but is subject to some variation due to disturbances in the uneven distribution of the spiral arms and mass, and we are currently in orbit close to the galactic point 1 8. The solar system orbits approximately once per billion-year, which can be called a galactic year, so the age of the Sun is estimated to be 20 25 times around the Milky Way. The orbital speed of the Sun is 217 km/s, which means that it can move 1 astronomical unit every 8 days, and it can travel a distance of 1 light-year in 1400 years.

In fact, in the Milky Way, the Sun can revolve around the huge black hole at the center of the Milky Way every day. In the solar system, the Sun has eight huge planets orbiting it. The sun orbits the solar system for hundreds of millions of kilometers every day.

And also led the eight planets to orbit together. The speed is very fast, and the earth also revolves around the sun...

The direction in which the Sun travels, also known as the Solar Steering Point, indicates the path of the Sun as it travels within the Milky Way, essentially in the direction of the Pure Weaver Girl, near the constellation Hercules, about 86 degrees away from the center of the Milky Way. The Sun's orbit around the river is roughly elliptical, but is subject to some disturbance by the uneven distribution of the spiral arms and mass, and we are currently in a position close to the orbit near the galactic center point 1 8. The solar system orbits about once every billion years, which can be called a galactic year, so the Sun has already circled the Milky Way 20 25 times based on the age of the Sun.

The orbital speed of the Sun is 217 km s, which means that it can move 1 astronomical unit every 8 days, and it can travel a distance of 1 light year in 1400 years.

Based on the above information, we can see that the solar system is located in the approximate plane of the galactic disk, about 86 degrees away from the center of the galactic galaxy, and is currently in an orbit close to the perigalactic center point 1 8.

At the top is the local group of galaxies, and at the top is the local supergalaxy, and on the network it is the total group of galaxies. In Total Galaxy, we can observe the general term for all the large and small galaxies in the universe.

The "Local Group of Galaxies" consists of about 50 galaxies and spans about 10 million light-years. Our Milky Way, with the Andromeda Galaxy, is the two largest galaxies.

Further up is the "Local Supercluster", which has a long longitude of 30 75 million parsecs, and is a collection of many galactic clouds and clusters, including the Local Group of Galaxy, the Virgo Cluster, the Ursa Major Cluster, and about 50 smaller groups and clusters of galaxies. The Local Group is only a small part of the Local Supercluster.

Further up is the "total galaxy", which is the general term for all the large and small galaxies in the universe that we can observe.

The solar system cannot be called a galaxy, the Milky Way itself is a galaxy. Every star like the Sun corresponds to a "solar system", and there are about 100 billion stars in the Milky Way, which means that there are 100 billion such "solar systems".

The Milky Way is provincial, and further up is the national level.

There is only one sun in the Milky Way.

There is only one celestial body in the Milky Way called Taipei Xunyang, which is the closest star to the Earth, and it constantly provides light and heat to the Earth. And if there are as many celestial bodies as the Sun in the Milky Way, there are as many as 100 billion.

Astronomers call objects that can export energy outward for long periods of time through nuclear fusion reactions (initially hydrogen fusion), and in the solar system, only the sun is a star. Compared to most other non-stellar objects (e.g., planets, asteroids, comets), stars are much more massive. You know, if you add up all the celestial bodies in the solar system except the sun, their total mass is only that of the sun.

Introduction to the Milky Way

The Milky Way is a barred spiral galaxy (a type of spiral galaxy) in which the solar system is located, with an elliptical disk shape and a huge disk structure, and the latest research shows that the Milky Way has four well-defined and fairly symmetrical spiral arms, which are 4,500 light-years apart. The number of stars in the Milky Way is between 100 billion and 400 billion.

The Milky Way galaxy is composed from the inside to the outside, including the galactic heart, the galactic core, the galactic disk, the galactic halo, and the galactic crown. Most of the Milky Way Lazhong state system** regions are old stars (mainly white dwarfs), and most of the outer regions are nascent and young stars. There are more than a dozen satellite galaxies scattered around an area of hundreds of thousands of light-years, and the Milky Way grows by slowly devouring the surrounding dwarf galaxies.

There is usually only one sun in the Milky Way because the solar system is a single star system.

At night, the stars that can be seen with the naked eye are all Hengshizhou Pixing, which is relatively close to the Earth. The Milky Way is a spiral galaxy with a diameter of about 100,000 200,000 light-years. According to scientists' estimates, there are about 100 billion 400 billion stars in the Milky Way, and the Sun is just one of the hundreds of millions of stars in the Milky Way.

The Milky Way is very big, so there are many stars like the Sun in the Milky Way.

A star is a luminous celestial body that is mainly composed of hydrogen, which is fed by nuclear fusion inside. The stars in the universe are also not exactly the same due to their different masses.

Scientists classify the stars according to the spectrum, and the scattered suns are classified as yellow dwarfs. However, yellow dwarfs are not the most numerous star class in the Milky Way. The most numerous stars in the Milky Way are red dwarfs, which account for about 82% of the total number of stars in the Milky Way system, while yellow dwarfs account for only about 3% of the total number of stars in the Milky Way.

The mass of the stars in the universe:

In general, the mass of stars in the universe is generally between 300 times the mass of the sun.

Red dwarfs have a mass of about a mass of the Sun, and Proxima Centauri, the closest star to the Sun, is a red dwarf with a mass of about one-tenth the mass of the Sun. Whereas, the mass of a yellow dwarf is about a double the mass of the Sun. Stars with masses between red and yellow dwarfs are called orange dwarfs, and they make up about 8% of the Milky Way.

In terms of quality, the more massive the star, the rarer the number. In fact, most of the stars in the universe are smaller and more massive than the Sun, mainly red dwarfs. In fact, the Sun is more massive than 90% of the stars in the Milky Way.

There is one sun in the Milky Way, the sun is a star close to the earth, the sun is the only star that can provide light energy and heat to the earth, if it is a celestial body like the sun, there are hundreds of billions, the sun is the center of gravity in the solar system, and the current life span of the sun is 100 million years.

There is one sun in the Milky Way, which is the closest star to the Earth, constantly providing light energy and heat to the Earth, but there are hundreds of billions of celestial bodies like the Sun. The Sun is the central celestial body in the solar system, which occupies the total mass of the solar system, and the eight planets all revolve around the sun.

The Sun is a star located in the center of the solar system, revolving around the center of the Milky Way, and the current life span of the Sun is about 100 million years, and after about 506 billion years, the hydrogen in the Sun will be almost completely depleted.

Different stars have different lifetimes, the smaller their masses, the slower the fusion reactions, but they will burn longer, up to 10 billion years for planets with a similar mass to the Sun, and hundreds of billions of years for planets with only 1/10 percent of the mass of the Sun.
