R136a1's heat would probably vaporize all of the planets.
Both are stars. Other than that, not much: R136a1 is a Wolf-Rayet star, and is both the most massive and the most luminous star known, making it quite different to our Sun. Its large mass (and corresponding high energy output) also make it relatively short-lived.
it would blow up!
it melts
It's a similar star in most respects to our Sun, slightly larger, but the increase in size, would probably be offset by an increase in revolution. So probably not much. It might be a little warmer and the years should be shorter, but in all other aspects - life would go on as normal.
R136a1 is the brightest known star. VY Canis Majoris. Its bolometric luminosity is estimated at 8.7 million times that of our Sun. VY Canis Majoris has a bolometric luminosity estimated at 450,000 that of the Sun, which is still very powerful. Bolometric luminosity refers to the entire radiation emitted at all wavelengths (not only visible light), so it is a measure of the power emitted by the star.
R136a1 is the most massive star known. It has a temperature of about 53,000oK. Our Sun for comparison has a paltry 6,000oK.
R136a1 is the biggest star known to the mankind.It is 320 times bigger than our sun and is of blue colour.
R136a1 is the most luminous at about 8,700,000 times more than the Sun. VY Canis Majoris is only 450,000 times more luminous than our Sun.
If the star Betelgeuse replaced the Sun, most planets will be inside the star, even Jupiter. It would outshine the Sun like the Sun outshines the Moon.
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.
Both are stars. Other than that, not much: R136a1 is a Wolf-Rayet star, and is both the most massive and the most luminous star known, making it quite different to our Sun. Its large mass (and corresponding high energy output) also make it relatively short-lived.
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.
nothing would happen, the sun is constantly going through nuclear reactions
there are many stars larger than the sun. for ex. vy canis majoris, the largest star known, rigel, sirius, r136a1 etc.
Nothing would happen if the moon was on the left and the sun on the right. The moon and sun are often on different sides of the earth.
The sun would win.
It would melt.
