What happens when Earth is engulfed in a comets coma? : Lets speculate!
Purely hypothetical and speculative thread here... However this is a 100% possible scenario, IMO...

What would happen if a comet with a very large coma passed closely enough to Earth that our planet became completely engulfed in the coma?

I know ISON will not pass closely enough to Earth for this to happen. Even if the coma explodes and expands after passing the Sun, it would have to be a gigantic expansion to reach Earth. However, other comets, in the future may come close enough.

So what would happen to Earth?

Would it depend on what gasses make the coma? Let's just say it was the average composition of gasses for comets, average for what we know to exist.

Would it block the sunlight, or just filter it?
Would the sky be a strange color as it passed by?
Would it have any effect on electricity, the power grid, or other?
Would there be more lightning from the friction created by the particles in the coma?
Would there be fall-out... comet dust fall all over Earth?

Do we have any record of this ever happening before?

Maybe a plague.

Some people believe the Black Plague was caused by a comet.

No, you don't.

The sky will be orange-ish pink. It may block or amplify sunlight. I'm sure somebody knows what materials are present...unless of course they are unknown materials.....

I see several days...maybe three...of a constant and intermittent hail of hot rocks and fire-stones. Every mineral or substance in the debris field of the comet will heat up as it enters our atmosphere. It will be the luck of the draw as to where it lands.gasp

Fires everywhere. Forests full of bugger-outters engulfed in massive firestorms. The smoke and burned chemicals permeate the air with gases that sicken and kill both men and animals.

The cities fare a bit better in the long run as few trees are available for fuel. Houses will burn...but hit and miss. The streets will be covered in broken glass.

Some incoming rocks will be tiny...like being hit by machine guns with 22 shells.

Some rocks will be huge and take out entire areas...filling the skies with soil and smoke. Much will rise high enough to stay in the atmosphere for weeks or more...making it dark and cold after the fires burn out.

That is the comet's coma part...it does not include the destruction from earthquakes and the possible crustal shift...gasp

Have a nice day.

You would see a few extra shooting stars by night. The comet would be very prominent in the sky.

Last time that happened we had the great chicago fire and phestigo fire in wisconsin. Everything exploded in flames and burned up. It has been reported the flames danced from place to place as things burst into fire that should not have.

And then after all that has happened, it's tail of ice will sweep over the planet and flash freeze everything in existence. Earth will resemble the ice planet Hoth from Star Wars.

Comet Venus? I'm not so sure about that theory, I can't prove it wrong but I just believe either.

Why would anything happen?

If it breaks up going around the sun and turns into buckshot. We can talk
