We would all be killed in the supernova explosion that created the pulsar out of our Sun. The Earth itself would be vaporized. Any returning space travelers would be fried by the intense pulses of gamma radiation that give the "pulsar" or "pulsing gamma ray source" its name.
However, this cannot happen - because our Sun isn't nearly massive enough to go supernova.
R136a1's heat would probably vaporize all of the planets.
No, a pulsar is not a part of the solar system. Pulsars are highly magnetized, rotating neutron stars that emit beams of electromagnetic radiation, while the solar system consists of the Sun, planets, and other celestial objects that are gravitationally bound to the Sun.
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.
oceans would dry
R136a1's heat would probably vaporize all of the planets.
No. A pulsar contains the mass of the Sun, squeezed into a ball 20km (12 1/2 miles) across
No. There is only one star in our Solar System, the Sun and it is not a pulsar.
no, it formed from a nebula, then condensed
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.
A Pulsar.
Our Sun is at least a 3rd generation star; the solar system formed from the debris blasted into space by countless - or at least, unknowable - numbers of supernova explosions of old dead stars. Some of those could well have left stellar cores that were pulsars. But it's unlikely that any of the Sun's mass was ever in a pulsar; the mass contained in a pulsar is so tightly bound by gravity that it is unlikely that any could ever escape. About the only way that any pulsar mass might have escaped would be if two neutron stars (and a pulsar is just a spinning neutron star) were to collide. Some of the mass might escape from the explosion, which would probably create a black hole as the result.
The sun would win.
It would melt.
No, a pulsar is not a part of the solar system. Pulsars are highly magnetized, rotating neutron stars that emit beams of electromagnetic radiation, while the solar system consists of the Sun, planets, and other celestial objects that are gravitationally bound to the Sun.
Because the new moon would have a higher gravitational pull, the earth would start to orbit around it as if it was the new moon's moon. This would cause the new moon to become a sun causing the Sun to crash into the new sun causing a supernova erasing the entire galaxy.
If Betelgeuse replaced our Sun, it would likely cause drastic changes in our solar system. Betelgeuse is a red supergiant star, much larger and hotter than our Sun, so Earth would be too close to it and would likely be engulfed by the star's expanded outer layers. The intense radiation and heat would also have significant effects on the other planets in our solar system.
