If it were spinning about 10% faster, it would break apart! The equator of Vega is 19% bigger than its polar radius. This is because Vegas has over twice the mass of the Sun and is spinning so rapidly (236.2 km/s at its equator), that it experiences centrifugal effects. While the Sun appears round, Vega is noticeably flattened. It is not visible south of 51° S, so it cannot be seen at all from the southern part of South America or Antarctica.Īlthough Vega and the Sun are both stars, they are very different from one another. In the Southern Hemisphere, Vega is visible low on the northern horizon during the Southern Hemisphere's winter. Further south, Vega is below the horizon more of the time and may be trickier to find. From a latitude including New York and Madrid, Vega is only below the horizon about seven hours a day, so it can be viewed any night of the year. In the mid-northern latitudes, Vega is almost directly overhead at night in mid-summer. In northern Canada, Alaska, and most of Europe, Vega never sets. You're looking for a bright blue-white star. Many allow you to wave the phone across the sky until you see the name. There are free phone apps that you can use to seek Vega by name or by its location. Declination: 38 degrees 47 minutes 01 second.The best way to find Vega (or any star) is to use its right ascension and declination: All three stars are extremely bright in a region with few other bright stars. Vega forms a right angle between the two other stars. Vega is at the top of the triangle, with Deneb below it and to the left and Altair below both stars and to the right. The ' Summer Triangle' consists of the bright stars Vega, Deneb, and Altair. Vega is seen in the summer sky in the Northern Hemisphere, where it is part of the constellation Lyra.
