Knowledge and common sense of the starry sky

I love the starry sky, it's something I've seen, and it's the constellations and bright stars that I can see now. Here's a reference for you.

Planet: Venus, emitting pale yellow light, maximum brightness, etc., also known as Chang Gung Star or Morning Star. Venus is called the morning star, and is visible in the east three hours before the sun rises; It is known as Chang Gung when it is three hours after the sun goes down and is visible to the northwest.

The current Venus is visible in the west, so it is also called Chang Gung Star.

If you see it from the southeast side around 9 o'clock, it's Jupiter, at its maximum brightness, etc., emitting white light. Located in the constellation Pisces.

constellations and stars; Antares in Scorpio, red, south sky.

Vega in Lyra, at the zenith.

Cowherd star in the constellation Aquila, at the zenith.

Tianjin IV in Cygnus, zenith (these three stars at the zenith are the famous summer triangle, which is now visible when it is dark.) The right angle is Vega, the 30-degree angle is the Cowherd, and the 60-degree angle is the Tianjin four).

Virgo's Horn One.

Arcturus in the constellation Pastorius, red (now located north of the zenith).

The Big Dipper in the constellation Ursa Major, visible in the north.

The above are the bright stars in the more obvious constellations.

At this time, Ophiuchus, Sagittarius, Libra, Ariurius, Shield, South Corona, North Corona, and Jackal can also be seen.

Autumn is visible and is now visible around 11 o'clock, such as Pegasus, Andromeda, Cassiopeia in the north, and Perseus rising in the east. Aquarius, Capricorn, and the north of the southern constellation are also very bright, as well as the Tusikong of the ceta.

It is better to know the stars to find the bright stars in the constellation, and compare them with the star map, and it is better for novices to see with the naked eye, not to use a telescope, the telescope field of view is relatively small, and it is more difficult to start.

I recommend you two software to know the starry sky, Sky Map and Stellarium, which are very useful. I learned about the starry sky by myself through them, and I also learned about it by printing star maps.

If you are a book, you can buy an encyclopedia book about the universe, which will definitely introduce some obvious constellations and stars, and you can learn a lot about the starry sky.

Starry Sky Astronomy Network (not bad, registered.)

Sirius Astronomy Network (A detailed introduction to the 88 constellations.

I also like the starry sky, so let's talk about it when I have time.

Hope it helps.

Use the search software "Google Starry Sky", which is very easy to use.

Hello, it is a pleasure to serve you and give you the following answer: Yes, knowledge can be compared to the starry sky, because they are all infinite and have no end. Problems can occur due to a lack of knowledge, or a lack of knowledge.

The solution is to learn more, think more, practice more, and accumulate more knowledge. Steps:1

First of all, it is necessary to clarify your learning goals, determine the direction of learning and the content of bending; 2.Secondly, it is necessary to collect relevant knowledge, which can be obtained through books, the Internet, lectures and other means; 3.Then, we should combine the actual situation, apply the knowledge we have learned to practice, and continue to accumulate experience; 4.

Finally, we should constantly summarize and sort out the knowledge we have learned to form our own knowledge system. Personal heart: Learning knowledge is a long process, and it requires perseverance and continuous accumulation in order to have more knowledge.

Tips:1Insist on learning and constantly improve yourself; 2.

Apply the knowledge you have learned to practice and continue to accumulate experience; 3.Summarize the knowledge learned and form your own knowledge system; 4.Share your knowledge with others to benefit more people.

Knowledge of the starry sky: The solar system is a collection of all celestial bodies constrained by the sun's gravity: 8 planets, at least 165 known moons, 5 identified dwarf planets, and hundreds of millions of small solar system bodies.

A star cluster is a system of celestial bodies composed of a dozen to a million stars with a common origin and strong mechanical connections with each other.

Stars are spherical or globheroid objects made up of hot gases that emit light on their own. The more massive the star, the shorter the lifespan, and the less mass, the longer the star's lifespan. Most stars are between 1 billion and 10 billion years old.

A planet usually refers to a celestial body that does not emit light on its own and orbits a star. Its rotation is often in the same direction as the rotation of the star it orbits. Generally speaking, planets need to have a certain mass, and the mass of the planet must be large enough to be nearly spherical, and it cannot undergo nuclear fusion reactions like stars.

In general, the planet must be more than 800 kilometers in diameter and have a mass of more than 500 million tons. The so-called "nine planets" of the solar system are a popular term in history, namely Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. In Resolution 5 adopted at the 26th International Astronomical Union held in Prague on 24 August 2006, Pluto was classified as a dwarf planet and named asteroid 134340, removing it from the nine planets of the solar system.

So now there are only eight planets in the solar system.

Meteors refer to the traces of light produced by meteoroids orbiting in interstellar space (usually including space materials such as cosmic dust particles and solid blocks) that are attracted to the earth due to the perturbation of the earth's gravity when approaching the earth, thus entering the earth's atmosphere and rubbing with the atmosphere. Meteoroids originally orbited the sun, and when they passed near the earth, they were affected by the gravitational pull of the earth and changed their orbit, thus entering the earth's atmosphere. There are several types of meteors: single meteors, fire meteors, and meteor showers.

Most visible meteoroids are about the size of a grain of sand and weigh less than 1 gram. Meteors enter the atmosphere at speeds between 11 km s and 72 km s.
