NASA has identified a neutron star vagabund that will reach our solar system in 1,000 years? What to do?

A source would be nice.

As far as I know, the next known neutron star is 200 light-years away and will have reached the closest proximity to our solar system in 300,000 years – still 170 light-years.


As a thought experiment:

It depends on which part of our solar system it reaches.Since he will not stop here, we are talking about a flyby.

Neutron stars have between 1.5-3 solar masses, our solar system has a diameter of pi by thumb 1.5 light-years.

A fly-by on the outer edge of the solar system would be a probable scenario (instead of a “full hit” in the form of a flythrough through the solar system itself), similar to the star Gliese 710, which in about 1.3 million years is believed to be the Oort cloud will penetrate.

The gravity of such a body would be the greatest threat.In the event of a “remote” flyby at the edge of the solar system, there is a risk that the vagabond would interfere with the orbits of objects in the Oort cloud, which could then lead to an asteroid bombardment of the Earth.

Here the necessary measures are clear – you have 1000 years to develop an appropriate defensive system.Presumably this can also succeed and the main problem will then be funding for 1000 years, rather than technical hurdles.

I wouldn’t be surprised if for 995 years various people and political groups deny the neutron star’s approach (fake news!) and want to leave the development community of a planetary defensive system.That is how climate change works.

If a higher approach to the solar system core is to be assumed, at least the inner planets are lost without rescue.Their orbits are disturbed and they themselves are probably thrown out of the solar system or into the sun.

The question now is how society handles it.Does she deny it? Are doomsday cults emerging? Is there any interest in giving humanity, or at least its heritage, a chance to escape?

If that were the case, then in 1000 years we would surely get a reasonably passable generational spaceship.Or at least a few probes with embryos, data archives and fully automatic colonization and cloning systems. Perhaps a society digging itself into a dark, cold hiking planet.

But it is also probable here that significant parts of humanity will deny the danger or refuse to cooperate (why should I renounce… I’m already dead… etc) the corresponding means cannot be raised and humanity becomes a remnant on a cold planetary wanderer (or plunges into the sun in a spiral orbit).

In this case, they probably discuss, until the last day, about really important things… so diesel, meat sausage and Islam.
