When stars collide
and got lots of good hits, including a Wikipedia article. Have you already been through that hit list?
anorlunda said:It would depend on velocities and on how direct/glancing the collision was. Two stars might merge or they might not. Ditto for the planets, effects range from minimal to destruction depending on the velocity and angle of the second star, plus the direct hit/glancing hit extent of a collision.
I don't see any significant difference between two sun-size stars or two exact copies.
If the Sun were to collide with a similar star, it would likely have catastrophic effects on Earth. The intense gravitational forces and energy released from the collision would cause major disruptions in the Earth's orbit and rotation, potentially resulting in extreme weather patterns, earthquakes, and tsunamis. The increased radiation and heat from the collision could also make Earth uninhabitable.
It is possible that the Sun and the other star could merge to form a larger star. This would depend on the size and velocity of the stars at the time of the collision. If the stars were moving at high speeds, they may pass through each other without merging. However, if they were moving at slower speeds, they could potentially merge to form a single, larger star.
The other planets in our solar system would also be impacted by the collision of the Sun and a similar star. The gravitational forces and energy released from the collision would cause disruptions in their orbits and potentially lead to collisions or ejections from the solar system. Additionally, the increased radiation and heat from the collision could affect the atmospheres and surfaces of these planets.
It is unlikely that we would be able to see the collision of the Sun and a similar star from Earth. The immense distances between stars and the vastness of space would make it difficult for us to observe such an event. However, if the collision were to occur within our own solar system, it is possible that we could witness some of the effects, such as changes in the appearance of the sky and potential disruptions in communication and technology.
The collision of the Sun with a similar star would likely have a significant impact on its lifespan. The energy released from the collision could cause the Sun to expand and become a red giant, potentially consuming some of the planets in our solar system. Alternatively, the collision could disrupt the Sun's fusion reactions, causing it to burn through its fuel at a faster rate and shorten its lifespan. Either way, the collision would significantly alter the Sun's evolution and eventual fate.
