I think that it would be to hot to live on earth and we would have never existed
Not quite sure what the intended question was - - - which star are you asking about? The sun IS a star - the one our planet orbits.
The blue star is hotter
If the Sun was a class "O" star and thus appears "blue", then I think there would be no life on Earth to ask the question. Our star - the Sun - is a class G2 star and has a temperature range of around 5,500 kelvin whereas an "O" star is > 30,000 kelvin.
A yellow sun, like our Sun, has a surface temperature of about 5,500 degrees Celsius (9,932 degrees Fahrenheit). In comparison, a blue star, such as a B-type star, can reach temperatures exceeding 10,000 degrees Celsius (18,032 degrees Fahrenheit) or more. Therefore, a blue star would have the greatest temperature compared to a yellow sun.
It happens all the time. What happens to the Sun? Nothing at all.
An average blue giant is about 5-10 times the size of the Sun and are much hotter than the Sun is. If our Sun were a blue giant, life, as we know it would never have happened. The Earth would have been vastly too hot to support abiogenesis.
Convert into a dwarf white star which is really hot, then a neutron star, and finally, a black hole.
The distance between the Sun and a blue star can vary greatly as there are many different types of blue stars in the universe. Blue stars can range in distance from a few light-years to thousands of light-years away from the Sun.
The earth would only rotate the sun because the sun is a star so only stars and meteors would be left.
Blue dwarf diameter(sun=1)=4 times the sun's Blue dwarf mass(sun=1)=10 times sun's
A falling star or shooting star is not a star but a small piece of space debris - a meteoroid - about the size of a grain of sand up to a boulder.In astronomical terms, the colour of an object is based on the temperature, and anything "blue" would have to be greater than 30,000 Kelvin - our Sun is a mere 5,778 Kelvin.A blue star is a massive hot star about 20 times larger than our own Sun. If one of these "fell" then all life as we know it would disappear.Falling stars are colorless or bright white streaks. It is not possible to have a blue falling star.
so what is the ponint sun is it a star of sume kind
