How much bigger is the star Vega compared to the sun?

Answer 1

Vega is a bit over twice as massive as our sun. It is also much whiter, and much hotter and more luminous than our sun. It is only about one-tenth the sun's age (500,000 years) but like our sun, it is about at the midpoint of it's life right now.

Answer 2

Our Sun is indeed headed in the general direction of 99 Hercules not far from the star Vega (and roughly away from Sirius in the other direction of the sky). However because of differing radial components of velocity - moving towards and away from the galactic center - and because of varying inclinations to the galactic plane (the Sun bobbing up and down below the Milky Way's disk during the cosmic year) they will miss each other by a significant distance (although some sources hint there may be enough gravitational interaction to perturb planetary orbits in our solar system). Their closest approach will probably happen in about half a million years - in which time the Sun should have completed a little over two more revolutions (orbits) around the galactic core.

Answer 3

The most massive known star is R136a1. You did ask about massive.

The largest star known is VY Canis Majoris.

R136a1 is about 35 times as large as our Sun.

VY Canis Majoris is about 2,100 times the size of the Sun.

Answer 4

The distance from the sun to the star, Vega, is 25.27 light years. This is equal to a distance of 148.5 trillion miles.

Answer 5

The Sun's diameter is about 115 times the diameter of Venus.

The Sun's volume is about 1.52 million times the volume of Venus.

Answer 6

The sun's volume is 1,520,000 times bigger than that of Venus.

The sun's diameter is 114.9 times bigger than that of Venus.

Answer 7

The radius of the star Betelgeuse is around 1,000 times larger than that of the Sun, and has a mass of roughly 20 times that of the Sun. So, indeed it is a very large star.

Answer 8

108 million km is the average distance it is from the Sun.

Answer 9

25.05 light years
