in 2020, Julianna Vega‘s age is 39 years. Vega brightness ranges from a magnitude of 0.127 to a magnitude of 0.068 over its variable period. It will Advertisement Advertisement. It will then sink towards the horizon, setting 6 hours and 56 minutes after the Sun at 23:12 (PST). It is also one of the Sun’s closer neighbours, at a distance of about 25 light-years. Vega’s distinctly blue color indicates a surface temperature of … Not officially a star and not officially a planet, but somewhere in between based the sizes of the stars. Brown dwarfs are strange altogether. The star is a pulsating Delta Scuti variable type which means that its size changes over time. Size of the star Vega in contrast to our sun. Roughly two and a half times the size of the sun, it is 40 times as luminous and, together with Arcturus and Sirius, one of the most radiant stars in the galactic neighborhood. White dwarfs are the smallest type stars, with a similar size to earth, and with extreme mass. The Variable Type is usually named after the first star of that type to be spotted. While size has relatively little impact on how bright stars appear to us due to the massive scale of distances in space, Vega’s size, proximity and distance all come together to make it one of the brightest stars we can see. Location. Vega is also about 2.1 times more massive than our sun, but only 0.54% of its total mass consists of elements heavier than helium, making it a weak Lambda Boötis-type star. Vega was the nearest star to the North Celestial Pole around 12,000 BCE and will take over as the northern pole star again around the year 13,727. Image via RJHall/ Wikimedia Commons. While size has relatively little impact on how bright stars appear to us due to the massive scale of distances in space, Vega's size, proximity and distance all come together to make it one of the brightest stars we can see. Vega is a massive star, about twice as large as our own sun. It’s the Once and Future North Pole Star This shape comes from the star’s rapid rotation: It completes one rotation every 12.5 hours, more akin to Jupiter’s … 3. The smaller the magnitude, the brighter the star. Vega (Alpha Lyrae) is a blue-white star in the constellation Lyra (the lyre, see … Vega, brightest star in the northern constellation Lyra and fifth brightest in the night sky, with a visual magnitude of 0.03. Vega is a classic class A (A0) white main sequence dwarf star, like the Sun quietly running off the nuclear fusion of hydrogen deep in its core, with a sort of average effective surface temperature of about 9500 degrees Kelvin. From Redmond , Vega is visible in both the dusk and dawn skies.In the evening, it will become visible around 16:55 (PST) as the dusk sky fades, 46° above your western horizon. Vega’s spectral type is A (white) and its luminosity class V (main sequence). Vega also exhibits an equatorial bulge, but in the star’s case, the bulge is enormous — enough to seriously distort the star into an ellipsoid. Vega is part of an asterism of stars called the Summer Triangle, which consists of Vega in the constellation Lyra, Altair in Aquila, and Deneb in Cygnus. Vega has a circumstellar disk of dust in its orbit, and irregularities observed in the disk indicate that there is at least one planet orbiting the star, with a size comparable to that of Jupiter. Vega is a massive star, about twice as large as our own sun. The mass of these stars can be equal to that of the sun. Its white color and apparent brightness made it a basic standard against which the apparent magnitudes of other stars are compared. Julianna Vega was born on July 5, 1981, in Havana, Cuba.
