# Are there any stars that one day we could collide with?

I'm not talking about tomorrow but in the far far future could we say our Sun could collide with another star or otherwise within our current detectable range?

• if there was a galaxy of melons in the sky about 2-7 kilometers average distance, how often would 2 of them collide. if you add the number of melons that you can fit on a 4.5 kilometer diameter sphere, the chance of the planet hitting another star in the coming million years is about 1/the total number of melons. – com.prehensible Oct 3 '18 at 22:40
• Wikipedia lists a number of past and future close approachs, which "close" being relative. The closest listed will be about $\frac 1 6$ of a light year in about 1.2 million years from now. – StephenG Oct 4 '18 at 0:13
• This is slightly related visualisation of galaxy density though it refers to the center of the galaxy where the star density is much higher than here, and I think there may be another Q&A of this type here or in a related SE site but I haven't found it yet. – uhoh Oct 4 '18 at 4:50
• Depends on whether there's enough mass (dark or otherwise) to cause the universe to collapse back into a singularity. – Carl Witthoft Oct 4 '18 at 18:48
• Imagine a cherry in Portland and another in Montreal. So rates the distance of the stars, compared to their sizes. – peterh - Reinstate Monica Oct 4 '18 at 20:53
