What is the closest galaxy to the solar system and where? How far?

One such star system that has been discovered so far is the constellation E. Epsilon. It is located at a distance of light years from Earth. For more information, please see the following page.

The closest galaxy to the solar system is the Andromeda Galaxy.

The Andromeda Galaxy, a spiral galaxy with a giant **-like structure located in the direction of Andromeda, is numbered M31 in the Messier catalog, and the new catalog number of the nebula cluster is NGC224, with a diameter of 220,000 light-years and 2.54 million light-years from the Earth, making it the closest large galaxy to the Milky Way.

The Andromeda galaxy appears as a spindle-shaped elliptical spot in the northeast-facing sky and is one of the most distant objects visible to the naked eye. The Andromeda Galaxy is generally considered to be the largest galaxy in the local group of galaxies, similar in appearance to the Milky Way. The members of this group of galaxies include the Andromeda Galaxy, the Milky Way, the Triangulum Galaxy, and about 50 smaller galaxies.

Based on improved measurement techniques and recent research results, scientists believe that the Milky Way has a lot of dark matter, and that the mass of dark matter is the largest in this group of galaxies.

In the Andromeda galaxy in the universe. It's an extragalactic galaxy that's relatively close to the Milky Way, and it's about 2.54 million light-years away. For humans, this distance is out of reach.

2.54 million light-years is equivalent to 240 billion billion kilometers. The Parker Solar Probe, described as 192 kilometers, would take nearly 4 billion years to cover this distance.

Since the Andromeda Galaxy itself is bright enough, it contains a whopping 1 trillion stars. Its actual brightness is 34 billion times brighter than that of the Sun and twice that of the Milky Way. This allows us to see this extragalactic galaxy directly with the naked eye, even from far away Earth.

And because the Andromeda Galaxy is so large, its diameter is estimated to be up to 220,000 light-years. So the Andromeda Galaxy doesn't look like a bright spot, and its apparent diameter can be up to six times that of the Full Moon.

Andromeda Galaxy.

With a diameter of 220,000 light-years and a distance of 2.54 million light-years from Earth, it is the closest large galaxy to the Milky Way.

The closest planetary system to the solar system is the Centauri Centauri, which has three stars, of which Proxima Centauri is only light-years away.

Centauri star is also known as Centauri star, in ancient China called Nanmen two, there are three stars in the planetary system orbiting each other, if we are in the galaxy, then there will be 3 "suns" in the sky, one of which is closest to the earth called Proxima Centauri.

Within ten light-light years of the solar system, there are ten stars in seven planetary systems, and their distance from the solar system is as follows:

1) The star Centauri, which contains three stars: Centauri A, Centauri B, and Centauri C (Proxima Centauri), located light-years from Earth;

2) Barnard's Star, located 6 light-years from Earth;

3) Wolf 359 star, light years from Earth;

4) 21,185 stars of Laland, light-years from Earth;

5) UV Cetaceid, light-years from Earth;

6) Sirius, a binary star system containing Sirius A and Sirius B, located light-years from Earth;

7) ROSD 154 star, light-years from Earth;

It is important to note that the relative positions of the solar system and other stars are constantly changing.

For example, the star Gliese 44, which is currently light-years away from the solar system, is moving towards the solar system at a high speed, and it is expected that in 40,000 years, Gliese 44 will become the closest star to the solar system, the closest is only light-years, and then gradually move away.

In addition to the Centauri star and Gliese 44, there are other stars that are getting closer to the solar system, and the following diagram shows the relationship between several stars near the solar system and the distance from the solar system:

We see that stars such as Centauri Samsung, Gliese 44, Ross 248, Ross 128 and so on will become the closest stars to the solar system for some time in the future.

The closest planetary system to the Solar System (a galaxy similar to the Solar System) is the Centauri star, with Proxima Centauri just over 4 light-years from Earth. If it is a galaxy the size of the Milky Way, the closest is the Andromeda Galaxy, which is about 2 million light-years away from Earth.

The closest galaxy to the solar system is not fixed, and the closest galaxy to the solar system is currently the star Centauri, which has three stars, of which Proxima Centauri is the closest to us, only light-years.

The closest galaxy to the solar system is the star Centauri, also known as Centauri, which has three stars orbiting together, and the closest one to Earth is Proxima Centauri, which is only light-years away.

The three stars are A-Centauri, which is also the host star of this galaxy. Centauri B, is a companion star. C Centauri is also known as Proxima Centauri.

The closest planet to the sun is Mercury, the distance between Mercury and the sun is about 57.9 million kilometers, Mercury is also the smallest planet in the solar system, in ancient times in our country, Mercury also has the nickname of "star star", Mercury and the earth have the same rocky individual, belongs to one of the four terrestrial planets in the solar system.

The orbital period is days, and it meets the Earth once in about 116 days, and its orbital speed is much faster than that of other planets in the solar system. Mercury is known as Mercury for its rapid movement, and is the messenger god of Roman mythology.

Mercury is the planet with the largest temperature difference between day and night on the surface, and its atmosphere is extremely thin to effectively retain heat, with temperatures reaching up to 432°C at the equator during the day and dropping to -172°C at night.

Problem Description: I would like to know: How far away is each planet in the solar system from the sun? Use it for homework. Ask the expert for a favor.

Analysis: The Solar System is a system of celestial bodies constrained by the Sun's gravitational pull, and its maximum range extends to about 1 light-year away. The main members of the solar system are:

The Sun (star) is a rock, nine planets (including Earth), countless asteroids, numerous moons (including the Moon), as well as comets, meteoroids, and large quantities of dusty matter and thin gaseous matter. In the solar system, the mass of the sun accounts for the total mass of the solar system, and the total number of other celestial bodies is less than that of the sun. The Sun is the central celestial body, and its gravitational pull controls the entire solar system, making other celestial bodies revolve around the Sun, and the nine planets in the solar system (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto) all revolve around the Sun in the same direction in a near-circular orbit close to the same plane.

The closest galaxy to our Milky Way

The Large Magellanic Cloud and the Small Magellanic Cloud are also hundreds of thousands of light-years away from our Milky Way.
