Where is the Solar System in the Milky Way?

Our Earth is located in the solar system.

The Sun is an ordinary star, and stars like the Sun are very common in the Milky Way. According to current astronomical observations, the Milky Way is a spiral galaxy.

And it has a rod-like core structure. This means that the position of the solar system is on the spiral arm, which is also an observation of modern astronomy. The number of spiral arms in the Milky Way is at least two, due to the galactic core.

It's hard to see what the other side of the galaxy looks like. But scientists speculate that the Milky Way has at least two or more spiral arms, and the Sun is located on a spiral arm called Orion.

The solar system is located on the spiral arm of Orion, which is one of the four spiral arm structures of the Milky Way, and the spiral arm is also quite lively, with relatively high brightness and density on the whole, second only to the center of the Milky Way.

Zone, according to the size of a city, Orion spiral arm is also a prosperous commercial area, with dense lights (stars) and dense flow of people (materials).

Because of the huge scale of the Milky Way, the solar system rotates in the Milky Way with the Orion spiral arm, with a speed of up to 220 kilometers per second, so the Earth moves very quickly in the universe. The spiral arms are equivalent to highways, and there are 4 highways like this in the Milky Way, and the other three spiral arms are Perseus.

of the spiral arm. The study of the spiral arm was observed using the trigonometric parallax method, with a radio telescope.

Capture the cosmic laser emission source, and then use the distance between the Earth and the Sun as a baseline to derive the distance from the radiation source.

The position of the solar system in the Milky Way also allowed for the creation of life, the center of the Milky Way is too dense and the radiation is too strong for life on Earth to exist, and the outer radiation of the Milky Way is relatively weak, and the material is very sparse, and the solar system may not have been able to form in the first place. No longer in the city center, nor in the suburbs, this life is still passing. If we are on the outskirts of the solar system, then dark matter.

It will definitely affect us, so the location of the solar system is ideal, not a suburb, not a center. Such an environment is more suitable for life and civilization, so it is not surprising that civilization appears in the solar system, and the arrangement of planets in the solar system provides a very suitable environment for the earth.

Edge. Because the Milky Way is very large and the Solar System is at the tail end of the Milky Way spiral, the Solar System is located at the edge of the Milky Way.

The solar system is located at the edge of the Milky Way, on the third spiral arm of the Milky Way, the Orion Spiral Arm.

The center of the solar system is the sun, although it is only a small and medium-sized star, its mass has accounted for the total mass of the entire solar system, and the remaining mass includes planets and their moons, planetary rings, as well as asteroids, comets, Kuiper belt objects, outer Neptune objects, theoretical Oort clouds, interplanetary dust, gases and particles and other interplanetary matter.

The total surface area of all the celestial bodies in the entire solar system is about 1.7 billion square kilometers. The Sun uses its strong gravitational pull to tightly control all the celestial bodies in the solar system around itself, making them revolve around itself in an orderly manner. At the same time, the Sun carries all the members of the Solar System around the center of the Milky Way.

The solar system is on the "rotors" of the Milky Way, at the very edge of the Milky Way, very far from the center of the Milky Way, revolving around the center.

The Solar System is located on the Orion Arm of the Milky Way, at a distance of about 26,000 light-years from the center of the Milky Way.

The Sun is about 25,000 to 28,000 light-years away from the center of the Milky Way and moves through the Milky Way at a speed of about 220 kms, making it possible to make one turn around the Milky Way in about 225 million to 250 million years.

This rotational cycle is called the galactic year of the solar system. The solar point, the path of the Sun through interstellar space, is currently pointing towards the constellation Hercules, near the bright Vega planet.

The position of the Sun in the Milky Way is a factor in the evolution of life on Earth. Its orbit is nearly circular and has about the same velocity as the spiral arm adjacent to the Sun, which gives life on Earth a long period of steady evolution, as the Sun hardly passes through the spiral arm, which concentrates a large number of supernovae, gravitational instability and radiation that could disturb the solar system.

The solar system is also in the periphery of the Milky Way, away from the crowded area at the center of the Milky Way. In the vicinity of the center, gravitational drag from neighboring stars can disturb the Oort cloud and send many comets into the inner solar system, causing potential disasters and impacts that collide and endanger life on Earth. The intense radiation from the center of the galaxy can also interfere with the development of complex life.

Even in the current location of the solar system, some scientists speculate that in the last 35,000 years, the closest supernovae may have caused some factors that were detrimental to the development of life, with radioactive radiation, dust particles and larger comet-like structures dispersed from the star's core likely to be thrown towards the sun.

Proximity. Fluff The solar system is in a local interstellar cloud or local fluff and is in the vicinity of the g-cloud, but it is uncertain whether the solar system is embedded in the local interstellar cloud or in the region where the local interstellar cloud and the g-cloud interact.

Local interstellar clouds are a region with a higher density of clouds within a looser, known as local bubbles. The local bubble is an hourglass cavity of about 300 light-years in interstellar matter that is filled with plasma, suggesting that it is some recent supernova** product.

Within 10 light-years from the Sun, the number of stars is relatively small. The closest is the South Gate II system of the Triad, which is about light-years from the Sun. South Gate 2a and b are a pair of closely related stars that resemble the Sun, while the small red dwarf, Proxima Centauri, orbits the pair at a distance of light years.

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.

Eight planets, asteroids, comets and other celestial bodies orbit around the sun according to a certain orbit to form the solar system. The Sun is the central celestial body, and it attracts all the celestial bodies in the solar system firmly around it with its strong gravitational pull, so that they rotate around it in an inseparable and orderly manner. Position of the Solar System in the Milky Way:

Located near the equatorial plane of the Milky Way, about 30,000 light-years (about 9,460.5 billion kilometers in 1 light-year) from the center of the Milky Way, the Solar System orbits the center of the Milky Way as an ordinary star. There are more than 200 billion stars like the Sun in the Milky Way.

The Sun is not in the Milky Way, the Sun is in the center of the Solar System.

The Sun is a star located at the center of the solar system, and it is almost an ideal sphere intertwined with hot plasma and magnetic fields. The diameter of the Sun is about 1,392,000 kilometers, which is 109 times the diameter of the Earth.

It is about 1.3 million times the size of the Earth; Its mass is about 2 10 kg. In terms of chemical composition, about three-quarters of the mass of the Sun is now hydrogen, and almost all of the rest is helium, including oxygen, carbon, neon, iron, and other heavy elements with less than 2% of the mass, which uses nuclear fusion to release light and heat into space.

The activity of the sun:

The sun looks calm, but in fact there is vigorous activity happening all the time. From the inside to the outside, the sun is divided into the solar nuclear reaction zone, the solar troposphere, and the solar atmosphere. One in 2.2 billion of this energy radiates to the Earth, becoming the main source of light and heat on Earth.

Active phenomena on the surface of the Sun and in the atmosphere, such as sunspots, flares and coronal mass eruptions, can greatly enhance the solar wind, resulting in many geophysical phenomena, such as increased auroras, atmospheric ionosphere and geomagnetic changes.

The enhancement of solar activities and solar winds will also seriously interfere with the normal operation of radio communications and space equipment on the earth, causing damage to the sophisticated electronic instruments on satellites and causing chaos in the ground communication network and power control network.

It could even pose a threat to the lives of astronauts on the space shuttle and space station. Therefore, it is increasingly important to monitor solar activity and the intensity of the solar wind and to make "space weather" forecasts in a timely manner.
