Vega is short period pulsating type of Delta Scuti type with a period of 4.6 hours. See Caph.
Vega is a young star relatively near us, where planets appear to be forming. There are also images of dust discs around Vega and other stars.

Vega is the 5th brightest star in the sky. Take a look at the list of the Brightest Stars
Vega, along with Deneb and Altair form the well-known Summer Triangle.

The bright stars Vega and Sirus are almost dead opposite of one another in the starry sky. So when one of these stars is at the verge of setting, the other star is always rising in the opposite direction.

Vega (1984-1986)
Overview
The only USSR mission to comet Halley was that of Vega - a mission involving two probes (Vega 1 and 2). They were identical crafts whose purpose was to carry probes to Venus and then intercept Halley in March of 1986.

Vega is of particular interest because it was one of the first stars for which a disk of dust was discovered surrounding a star. An infrared excess was discovered about the star in 1983 when the Infrared Astronomical Satellite (IRAS) observed it.

Vega, "Falling Eagle" or "The Harp Star", is only the fifth brightest star, but it dominates the summer skies in the northern hemisphere, with a transit date of 1 July.

Vega, along with Deneb and Altair form the well-known Summer Triangle.
About 4000 years ago, the star Thuban was the North Star. Since then, precession of the Earth's axis has changed where the North Pole points, so the North Star is now Polaris.

It was recognized as an incarnation of a bird of prey in many ancient Middle East cultures. Its brightest star, Altair, forms Summer Triangle together with Deneb (a Cygni) and Vega (a Lyrae).

The stars that had to be moved away from the Earth to place them at 10 pc are the Sun, Sirius and Vega. You know this because their absolute magnitudes have a larger numeric value than their apparent magnitudes - the stars became fainter.

of the brilliant star Vega; but was shifted nearly 7° to the S. W. by J. C. Kapteyn's inquiry in i 901; so that the range of uncertainty as to its position continues unsatisfactorily wide.

1P/Halley was also visited by the two Soviet spacecraft, Vega 1 and Vega 2, and two Japanese spacecraft, Sakigake and Suisei.
81P/Wild 2 was visited by the Stardust space mission in 2004.

The name we use for this star today, Vega, comes from the Arabic words al-nasr al-waqi' that can mean either ‘the swooping eagle' or ‘vulture', for the Arabs saw an eagle or vulture here.

Vega, (α Lyrae) is such a star. Stars hotter than Vega will have a negative colour index and appear more bluish. Stars with a positive colour index are cooler than Vega and will appear more yellow, orange or red.

The Earth's rotation axis happens to be pointing almost exactly at Polaris now, but in 13,000 years the precession of the rotation axis will mean that the bright star Vega in the constellation Lyra will be approximately at the North Celestial Pole, ...

The brightest stars"Vega, Deneb, and Altair"form a conspicuous triangle high above the constellations Sagittarius and Capricornus, which are low on the southern horizon. In the winter sky, however, these stars are replaced, as shown in Figure 1.

The Soviet Vega 1 and Vega 2 missions to Comet Halley in 1986 deployed atmospheric balloons in Venus' atmosphere en route to the comet. DSN tracked the instrumented balloons to investigate winds in the Venusian atmosphere.

Because of precession, Vega is destined to be the Pole Star in about 12,000 years. Entirely unconnected to this, the direction of the Sun around the Milky Way galaxy, with reference to external galaxies, is known as the solar apex.

Lyra contains the star Vega (the fifth brightest star in the night sky) and is one-third of the asterism known as the "Summer Triangle". Lyra represents the lyre or harp of the Greek musician Orpheus.

Magnitudes are typically measured with reference to an astronomical standard, usually the star Vega which has a magnitude of 0.0. Increasing magnitudes denote fainter objects, thus a star with a magnitude of -1.

The fifth-brightest star of the sky, alpha Lyr, called Vega (arabic for "stone eagle"), radiates from the top Lyra with a pure white colour. Together with alpha Cyg, Deneb , and alpha Aql, Atair, Vega forms the Summer Triangle.

Cygnus, with the bright star Deneb in the swan's tail, appears high in the summer sky. The three bright stars Deneb, Vega (in the constellation of Lyra), and Altair (in the constellation of Aquila) mark the Summer Triangle.

Travel to Vega and see how the Sun pales to a faint star, a star among thousands of others. Look at the Pleiades from behind! With ordinary red/blue 3D glasses your experience will be even greater.
