What are the brightest stars? Do you know which is the brightest star? Can you find it?

There are 18 in total:

South Heaven: Old Man Star (Ship Base) Horse Belly One (Centauri) South Gate II (Centauri) North Fall Master Gate (South Fish).

North Heaven: Sirius (Canis Major) Arcturus (Pastorus) Vega (Lyra) Five Cars Two (Auriga) Betelgeuse Seven (Orion) South River Three (Canis Minor) Betelgeuse Four (Orion) River Drum Two (Aquila) Aldebaran (Taurus) Antares (Scorpio) Antares One (Virgo) North River Three (Gemini) Tianjin Four (Cygnus) Regulus XIV (Leo).

Observed with the naked eye on Earth, the Sun is at its brightest, followed by Sirius, the Old Man Star, etc.

In terms of actual brightness, the sun is nothing at all.

American astronomers have discovered a new star, which is believed to be the largest and brightest of all the stars ever discovered, the star named LBV 1806-20 is about 500-40 million times brighter than the Sun, at least 150 times more massive than the Sun, and about 200 times the diameter of the Sun. According to the New York Times, if LBV 1806-20 is compared to the Sun, it is like comparing Mercury to the Sun.

Discovery: The brightest star in the universe.

A team of astronomers at the University of Florida in the United States recently said that they may have discovered the brightest star ever observed in the universe, "LBV1806-20". This "behemoth" may be 7 times brighter than the current stellar brightness record holder.

In its report to the current National Meeting of the American Astronomical Society in Atlanta, the team said that the star on the other side of the galaxy is 40,000 light-years away from us, so despite its brightness, we still can't see it in the night sky. Scientists can only detect it with the help of infrared measuring instruments.

The researchers say the star is at least as bright as the current brightness record. Pistol stars are 5 million to 6 million times brighter than the Sun, and LBV1806-20 may even be 40 million times brighter than the Sun.

Astronomers have been sporadically aware of certain cases of LBV1806-20 since the 90s of the 20th century. At the time, they identified it as a "high-luminosity blue variable star", a relatively rare, large, short-lived star.

In the evening, twilight falls and the stars shine. Do you know which is the brightest star in the starry sky?

On a winter night, in the southern starry sky, there are three bright stars that are easy to see, and the three stars are connected and are equilateral triangles.

It's called the "Winter Triangle".

These three stars are called: South River III (Canis Minor), Betelgeuse IV (Orion), and Sirius (Canis Major).

Among them, Sirius, is the brightest star in the whole day.

Sirius, also known as Canis Major A, is the brightest star of the day except the Sun. It is a blue-white main-sequence star with a white dwarf companion star, light-years from Earth, and a mass twice that of the Sun. The radius is about twice that of the sun, and the volume is about 5 times that of the sun.

In ancient Chinese astronomy, Sirius means the wolf in the sky, and in the Chinese "Twenty-Eight Nakshatras", Sirius belongs to the Jing Nakshatra. Sirius's apparent magnitude is equal. To the naked eye, it looks sparkling with a white glow.

As long as there are no clouds to obscure it, it is easy to find in the southern starry sky in winter, and it is particularly dazzling.

Excluding the Moon, the brightest star in the night sky is Venus.

When Venus is in the "full phase" (equivalent to the full moon), the brightness of the stars throughout the day is added together, and it does not grind the brightness of Venus.

When Venus is at the "great elongation of the east" and the "great elongation of the west", the light of Venus can still be seen in the sunlight burning at o'clock.
