It will have a shorter lifetime. The Sun should last about 10 times longer.
Vega is just over twice the mass of the Sun.
no the sun is a medium mass star.
Since it has about twice the mass of the Sun, you can expect it to be relatively young. Such massive stars burn out fairly quickly (for a star).
Earth would not be the same is the sun were replaced with a star with twice as much mass. There would be climate changes, changes in daytime and night time, which would offset almost everything.
Yes, Sirius is about twice as massive as our sun, making it a medium mass star. It is quite a bit brighter, however, and is the second brightest star in our sky.
It is, but at twice our suns mass, Sirius A is on the limit, of being an intimidate mass star. Sirius A will have a life cycle similar to that of our own star which is a low mass star, but burns hotter. Sirius B is a companion white dwarf star with a mass of around the same as our sun. Previously, it was thought to have been a star with a mass of around 5 times that of our sun, burning out more quickly than Sirius A.
The sun is an intermediate-mass star.
The Sun is a medium mass star on the main sequence.
During last ages of life of a star, to find what happens in coming ages of life of star. It determines on its mass explained by chandrashekher that if the mass of given star is 2.42 times the mass of our sun then it explodes in the form of supernova. If the mass of given star is less than the 2.42 times the mass of our sun then it shrinks to become white dwarf.
There are more low mass stars. this is for two reasons:- # the star forming process generates more low mass stars # High mass stars burn out very quickly and explode as supernovas and thus over time there are less and less of them.
Yes, Sirius is about twice as massive as our sun, making it a medium mass star. It is quite a bit brighter, however, and is the second brightest star in our sky.
If the sun was replaced by a star with twice as much mass the gravitational force would be unbalanced and the new sun would burn the earth because if the gravitational force cannot hold than the sun would plummet towards the earth and burn it.
