how close to the sun would the earth need to be to

[pontifex]

make the oceans boil and evaporate?
what would this do to the rest of the earth (plants, soil, air, etc)?

 

[krunchykrome]

I think if the sun was close enough to evaporate oceans, we'd all be dead.

Yeah, this is definitely a question for science gurus.
I mean, c'mon, who knows what would happen to all biological life at sterilizing temperatures, right?

well i'm not really asking what would happen to us, more like what it would do to the environment.

there would be no environment. It would be a dead planet.

I don't know but I think the tanning bed business would fold.

Aren't we considered an animal? I think we and all plant life would die.

ok, so i didn't word my question properly...give me a fvcking break

Ice caps melting would be my first thought... that would really mess with the water parameters and I'm not sure who/what would/could survive in those extreme conditions. With water parameters ruined, supporting life would be hard, especially the aquatic life forms. At that point, sure, it would boil and such, but that won't matter.

To answer your question, I'm not sure, we could maybe make estimates based on other planets between the Sun and Earth and the kind of temperatures they have. I'm not sure how to do this because you'd have to take the atmosphere into account.

Well somewhere between here and venus. That at least narrows it down a lot.

The two planets have a different make up but set in the same orbit I wonder how close they would become to resembling each other. Either way Venus is super hot at the orbit and range from the sun.

If the sun was close enough for solar energy to provide enough heat to bring elevently billion billion gallons of ocean to a boil, then all life, as we know it, would cease and all traces of life would be incinerated.

 

[pontifex]

would it remove all oxygen?
would it iradiate the ground or anything? would it be possible for humans to survive underground with current technology?

if that happened and somehow the earth moved back into position or to another position further away, would it be possible for life to start anew?

 

[FleshLight]

It's a complex question since the closer the sun is to the earth, the higher the input of longwave radiation. Such higher inputs would increase carbon emissions (by photosynthesis, fossil fuel use, etc), which increases the temperature of the earth and reduces albedo, increases sea level, etc. The oceans, clouds, and snow all reflect the radiation and their changes must be taken into account.

 

[irishScott]

There are so many factors that determine the Earth's temperature that it would be impossible to answer that conclusively without some insane research. The earth is not just a ball of water and land. The atmosphere, mantel, crust, and gravity would all affect everything in varying ways that would inevitably alter the temperature of the Earth in some way or another.

It's not as easy as asking how close to move water to the sun before it boils.

 

[AgaBoogaBoo]

Well, one thing that we should maybe estimate before trying to find the distance - how much of an increase in temperature is needed for it to boil?

Gee, I wonder

Somewhere between where our orbit currently lies and venus' orbit. Astronomically speaking, it wouldn't have to be very much closer for what you're describing to happen.

Venus is 67,084,000 miles from the sun and it is much like you describe and not all that different at least in size from Earth.

Earth is 93,000,000 miles from the sun. That is a difference of roughly only about 26 million miles. Just making a rough esitmate I'd say that if the earth were just half that distance closer to the sun it'd probably exterminate all life on the planet as we know it.

 

[theprodigalrebel]

Venus has a mean surface temperature of 450C. I guess halfway between the Earth and Venus, things will get really hot?

Most plant/animal life will start dying of heat/dehydration once temps start going north of 60C. Oh, and the polar ice caps would melt and spell doom for low lying coastal areas. Tsunamis and all sorts of cool stuff would start happening.

Too many factors, I am sure.

Solar flares would have to be taken into account. The average temperature of the sun and then how it dissapates has to be taken into account but I am guessing since space is ideal for experiementation (close to absolute zero), you can just figure how heat disappates. Boiling is 100 F or close to 22 C right, so then you would just calculate the dissapation factor and then match it as close to that number as possible (295 K). It may have to be slightly closer due to atmosphere, but I am betting that the atmosphere would be swallowed up and actually be fuel to raising the temperature so who knows.

**EDIT**
G2 stars have an average of 5500K. Anyone know a heat dissapation equation for space?

Stick your finger in your mouth. 2 degrees hotter is about 100F.

I think you mean 100C
