Two comets to cut it close to Earth’s orbit next week

What would our world be like if several thousand years ago an astronomer calculated that the orbit of a comet would cause a direct collision in the future? Our calendar would be a countdown of years so year 8 would mean eight years until the end of the world.

NO, No, remember it is all Trumps fault, then Bush’s fault. Get it right bud! Sarc.

There is also a luner eclipse of the blood moon the same day. Nobody notices that.

Assume this is the result of a comet which broke up and the breakup was recent. How confident should we be of the projected trajectory?

I know nothing about the subject and you seem to know a great deal. Any knowledge you can share is greatly appreciated. Thanks, "grania"

[JusPasenThru]

Will we be able to see Uranus?

[BenLurkin]

I certainly hope not, Ollie.

and you seem to know a great deal.

No, I know next to nothing.

Famously, comets can exhibit non-Newtonian motion when in the inner Solar System (due to heating). I.e., the eruption of geysirs / gas jets and other violent reactions can alter their otherwise Newtonian trajectories. But I don't believe that a significant alteration of their courses within only the next few weeks should be expected - at least, nothing of the order of magnitude that would be necessary to put them on a collision course with Earth, if that's your worry.

Looks like there’s a very minor penumbral lunar eclipse the day after - during the Fast of Esther. Interesting as the moon is likened to the Jewish People and lunar eclipses are “messages” for them.

I expect there will be 2 or 3 significant events next week.

Two comets will zoom by Earth next week within a couple million miles

Okay, I'm not going to worry about them. Get back to me when they find one that will pass within 75 feet of the Earth.

Thanks fieldmarshaldj.

Daddy would have gotten us Uzis...

Brussels airport, Brussels metro station.

[DeathBeforeDishonor1]

You called it but I dont think we are done.

[Mr. M.J.B.]

Agreed.

The next four days and mid to late April are of note here.

[DeathBeforeDishonor1]

I hear ya and now why. Later
