In summer, July 2018 is the brightest star in the southeast

It's Sirius. Sirius is the brightest star of the day except the Sun, but it is fainter than Venus and Jupiter, and brighter than Mars most of the time.

Sirius A is a blue dwarf star with a radius of about r. The optical interferometer measures the radius of the star and estimates the angular diameter to be MAS. It rotates at a speed of about 16 km s, so it does not effectively flatten the star into an ellipse.

Vega rotates at a higher speed of 274 km, making it an oblate sphere.

I'm also in this star.,It's been bright in the last week.,About 10 o'clock southeast.,Yellow light.,You can see this star with the naked eye on the edge of the moon.,The next app confirmed that it's Mars.,What Sirius Polaris is.,App can use star maps or nebulae.,There are free versions.。

Show that you are asking at 1:30 Beijing time at nightAssuming that you are in China, it is more likely to be Sirius, due southeast, not too far from the ground (the specific value varies with different locations, if it is about 15° in Beijing). Sirius is the brightest star of the day except the Sun, white, or miserable white, with a noticeable change in brightness and a sense of "jitters" as if the stars are "shaking".

If it's higher, it's also possible that Orion Alpha (Betelgeuse) is Venus and will only appear around the Sun, so it's only around dusk or dawn, so it's certainly not the star you're seeing.

Sirius, the star A of Canis Major, is located in the constellation Canis Major. Sirius is the brightest star of the day except the Sun, but it is darker than Venus and Jupiter.

Most of the time it is brighter than Mars.

Sirius is a blue-white main-sequence star with a white dwarf.

A companion star, the center of mass of the system is about light-years from Earth. Among them, Sirius B, the companion star of the white dwarf, is the earliest white dwarf observed by mankind and one of the most massive white dwarf stars. Sirius's English name is Sirius, which means "scorched" in Greek, because the ancients believed that when Sirius and the sun rose at the same time, it was the summer spike, and the light of Sirius and the light of the sun were combined to be the reason for the hot summer weather.

Jupiter.

Jupiter is the largest planet in the solar system, its volume is more than 1,300 times that of the Earth, and its mass is more than 300 times that of the Earth. "Jupiter opposition" refers to the phenomenon that the Earth and Jupiter reunite with the Sun in a straight line when they orbit in their respective orbits, that is, the phenomenon that Jupiter and the Sun's ecliptic longitude differ by 180 degrees, which is called "opposition" in astronomy.

At opposition to Jupiter, Jupiter is in the constellation Sagittarius, rising at 8 p.m. from the southeastern horizon and rising due south at midnight at about 20 degrees above sea level. It fell from the southwest at 4 a.m. The visible time of the night is 8 hours.

Life is possible. In 1953, Miller Yuri experimentally demonstrated that the combination of lightning and the regents present in the primordial Earth's atmosphere could form organic matter (including amino acids) that could be used as the building blocks of life. This simulates the composition of the atmosphere as water, methane, ammonia, and hydrogen molecules; All of this material was found in present-day Jupiter's atmosphere.

Jupiter's atmosphere has a powerful vertical flow of air that carries these compounds into the lower regions. But there are higher temperatures in Jupiter's interior, which will break down these chemicals and prevent the formation of life like Earth.

The middle of the Northern Hemisphere is in the middle of the eighth month.

The brightest Bai star in the southeast direction at night may be the main star of the Arcthyan constellation Dumen, which is about far from the Earth.

Light-year. It is a first-magnitude star, and it is the 18th bright star that can be seen on Earth in addition to the Sun.

Beiluo Shimen is a lonely star, and there are no other brighter stars around, so Beiluo Shimen has become the southernmost bright star that can be seen in most parts of China on autumn nights (the Lingnan area in Guangdong and Guangxi can see the brighter and more southerly Water Committee and even the old man's star).

Hello lz.

As you describe this.

There is a high probability that the star is the north fall Zhi Shimen.

That is, the star of Arctic Fish is almost 11 o'clock in late summer. It is a 1st magnitude star, and there are no bright stars around it, located in the south. [Another 2nd magnitude star of the constellation Cetus can be seen rising after about 12 o'clock later.]

In a city with heavy light pollution, it is indeed difficult to distinguish other stars that are so bright. 】

Venus. Venus.

Venus) is one of the eight planets in the solar system, and is the second planet in order of distance from the sun. It is the closest planet to Earth (Mars is sometimes closer). The ancient Romans called it Venus, in ancient China it was called Chang Gung, Qi Ming, Tai Bai or Tai Bai Xing, and in ancient Greek mythology it was called Aphrodite.

The orbital period is Earth Day.

The night sky is second brightest after the Moon, and Venus reaches its brightest only time before sunrise or after sunset. It appears in the eastern sky early in the morning and is called "enlightenment"; In the evening, it is on the west side of the sky and is called "Chang Gung".

Hello! Ask the brightest star in the southwest in summer, in fact, it also involves the specific time of the night, and the geographical version of your location.

It is the question of how many degrees north latitude, right.

The following is to take the region of 30 to 40 degrees north latitude in China, around 8 o'clock in the evening in August, for example, you can see three brighter stars near the overhead, the brightest one is Vega in the constellation Lyra, in the southeast of Vega, slightly darker than Vega is the Cowherd Star in Aquila constellation, in the east of Vega, there is a fainter star is Cygnus Tianjin Four, turn your eyes to the south, there is a brighter star in Scorpio is Antares, in the summer night of the city, due to the light pollution is more serious, The brighter stars that can be seen with the naked eye are basically these (except for the planets in the solar system), the following gives you a star map of the mid-latitudes of our country at about 8 o'clock in the evening in early August, I have marked the names of the constellations and some brighter stars, for your reference, thank you!

Can you go back? Looking up at the stars, I talk to myself. The stars twinkle, the insects play and sing softly, the dark night is lonely, and the withered flowers are reborn.

Feel the loneliness of a person

This may be the reason why people in the past cherished words, but always loved to praise hermits!
