Vega is the bright star near the bottom. Each night the positions of the stars appear to change as the Earth rotates. However, when a star is located along the Earth's axis of rotation, it will remain in the same position and thus is called a pole star .
The defining vertices of this imaginary triangle are at Altair, Deneb, and Vega, each of which is the brightest star of its constellation (Aquila, Cygnus, and Lyra, respectively). The greatest declination is +45° and lowest is +9° meaning the three can be seen from all places in the Northern Hemisphere and from the home of most people ...
The radiant of the meteor shower is located near the constellations Lyra and Hercules, near the bright star Vega. The peak of the shower is typically around April 22–23 each year. The source of the meteor shower are particles of dust shed by the long-period Comet C/1861 G1 Thatcher. [1]
Such multiple star systems are indicated by parentheses showing the individual magnitudes of component stars bright enough to make a detectable contribution. For example, the binary star system Alpha Centauri has the total or combined magnitude of −0.27, while its two component stars have magnitudes of +0.01 and +1.33. [3]
The easternmost star designated by Flamsteed, 19 Lyrae, is also a small-amplitude variable, an Alpha 2 Canum Venaticorum variable with a period of just over one day. [52] Another evolved star is the naked-eye variable XY Lyrae, a red bright giant [46] just north of Vega that varies between 6th and 7th magnitudes over a period of 120 days. [53]

It is classified as a Vega-like star that emits excess infrared radiation, [19] [20] indicating it is surrounded by a circumstellar disk. [21] Fomalhaut, K-type main-sequence star TW Piscis Austrini, and M-type, red dwarf star LP 876-10 constitute a triple system, even though the companions are separated by approximately 8 degrees.

Tommy Vega is officially in for the fight of her life. Monday’s episode of 9-1-1: Lone Star confirmed that Gina Torres’ character has stage 2B breast cancer. “Trust me, I did not want this ...
