The term "Vega star" refers to the star Vega (α Lyrae), which is the brightest star in the constellation Lyra and one of the brightest stars visible from Earth. As of my last knowledge update in September 2021, Vega is classified as an A-type main-sequence star, sometimes referred to as a "white star" due to its color. Its size can be described in terms of its radius and other physical properties: Radius: Vega has a radius of approximately 2.135 times that of the Sun. This means it is larger than the Sun in terms of physical size. Mass: Vega's mass is around 2.1 times that of the Sun. Luminosity: Vega is significantly more luminous than the Sun, with a luminosity about 37 times that of the Sun.
Vega isn't a planet, it is a star. It is the second-brightest star in the northern sky.
The apparent magnitude of Vega is 0.03. The absolute magnitude is 0.58.

Vega is relatively close at 25 light years. At one tenth of the speed of light, it would still take 250 years to reach it from our solar system.

A solar radii is used to express the comparison from one star to our own Sun. If a star has a radius of 10.3 solar radii, then it has a radius 10.3 times larger than the Sun

By the power of HYSTERIA! No, really, the solar system is in do danger from Vega.
Our solar system
The largest star in Orion is Betelgeuse with a solar radii of 1,180.
The largest star discovered so far is the UY Scuti red supergiant. It is approximately 1,708 solar radii, where one solar radii equals the radius of the Sun in our solar system.
Rigel has a radius of about 78 solar radii or 0.363 AU.
The largest known star now is UY Scuti with a diameter 2,375,828,000 km. UY Scuti has the radius of 1,516-1,900 solar radii, with the median radius of 1,708 solar radii, or approximately 7.94 astronomical Units.
Typically,giant stars have radii between 10 and 100 solar radii and luminosities between 10 and 1,000 times that of the Sun.Whereas Supergiants have a radii between 30 and 1,000 solar radii and luminosities between 30,000 and 100,000 times that of the Sun
