Vega is the fifth brightest star visible from Earth.
REPUBLIKA.CO.ID, JAKARTA — On a July night, in the east, there is a star known as the Summer Triangle. This group of stars also consists of three stars: Vega, Deneb and Altair.
After sunset, they are the first three stars to illuminate the eastern side of the sky. Even from a light-polluted city or on a moonlit night, this star triangle can still be seen.
Vega, the blue-and-white star in the Summer Triangle, is the brightest of the three stars. On a July night, Vega is the brightest star in the eastern sky. Vega is also the brightest star in constellation Lyra the Harp. As a result, Alpha Lyrae is another name for Vega.
Reported from Earth Sky, Vega is about a quarter light year away. Many people are familiar with the constellation Vega, Lyra. Triangles of stars connected to a parallelogram appear in this star pattern.
How to See Vega
Vega is first seen in the Northern Hemisphere at night around May. Vega shines strongly in the east at night during the northern summer. On autumn nights in the north, it is overhead, and on December nights, Vega is in the northwest.
Lyra is a small constellation with some unique features. Epsilon Lyrae, known to telescope users as a prominent double-star, can be seen near Vega.
After Sirius and Arcturus, Vega is the fifth brightest star visible from Earth. Vega is also the third brightest star that is easily visible from mid-northern latitudes.
The star’s distinctive blue color indicates a surface temperature of about 17,000 degrees Fahrenheit (9,400 degrees Celsius), about 7,000 degrees Fahrenheit (4,000 degrees Celsius) hotter than our sun.
This star has a diameter of 2.5 times the diameter of the sun and the mass below the sun. However, due to the pressure and interior temperature Vega significantly higher than the sun, the Vega will burn its internal fuel faster.
Vega is only one tenth the age of our sun. Vega will run out of fuel in half a billion years. The Vega spins rapidly, completing one full rotation around its axis every 12.5 hours. On the other hand, it takes our sun 27 days to complete one rotation.
