How much closer to the sun would the earth have to be before it was too hot to support life?

Pretty freakin close. But then again if the Sun even got that close we'd all die =P. I think the boiling point for water is like 212 degrees Fahrenheit, so if the sun moved like where Venus is, the oceans probably would evaporate pretty quickly. Maybe about half an AU.

∙ 14y agoThe area around a star, such as our Sun, within which a planet must exist in order to support liquid water and life is known as the circumstellar habitable zone (CHZ). For the Sun, the inner edge is believed to be about 0.725 astronomical units (AU) from the Sun. The Earth's average distance from the Sun is 1.0 AU.
Therefore, according to this estimate for the inner edge of the Sun's CHZ, the Earth could be up to 25.6 million miles closer to the Sun before it would be incapable of supporting life.
This topic is debated, however, with some scientists believing the Earth to be in a much narrower CHZ.

What would most likely happen if Earth moved closer to the sun?
It would burst up in flames. If earth moved closer to the sun we would all die and suffer of the heat of the sun and also if the earth got closer to the sun earth can most likely melt.
What would earth be like if the moon were closer to the earth?
If the moon were closer to earth there would be a stronger gravity pull on earth. It could be so strong that it would take us more then 10 minutes to take 6 steps!
What would happen if the sun came closer to earth and what would happen to the plants?
If the earth got pulled in closer to the sun, or if the sun expands significantly, then the earth will get much warmer. That said, nothing like that is going to happen for a couple billion years yet.
Would an object have a greater gravitational pull closer or farther from earth?
An object have greater gravitational pull closer from earth. As we get farther from earth, the gravitational pull becomes weaker. That is why objects sufficiently away from the earth do not fall on it.
Why does earth exerts a greater force than the moon?
There are two reasons: The Earth is more massive than the Moon, and the Earth is closer to you than the Moon. If you were standing on the Moon, then the force of gravity due to the Moon would be greater because you are closer to the Moon.
What if the earth will stop revolving around the sun?
The earth would be attracted by the sun, and as it came closer the sun, the earth would melt. The earth would probably collide with the sun before or after it would melt.
Why can't we live closer to the sun?
The closer an object is to the sun, the more heat it receives. If Earth were too close to the sun it would be too hot to support life.
If the moon were closer to earth high tides would?
If the Moon were closer to the Earth, the high tides would be higher, and the low tides would be lower.
What would most likely happen if Earth moved closer to the sun?
It would burst up in flames. If earth moved closer to the sun we would all die and suffer of the heat of the sun and also if the earth got closer to the sun earth can most likely melt.
What would happen to the Earth's oceans if the earth was closer to the sun?
oceans would dry
What would earth be like if the moon were closer to the earth?
If the moon were closer to earth there would be a stronger gravity pull on earth. It could be so strong that it would take us more then 10 minutes to take 6 steps!
Would earth be hotter if it were closer to the sun?
Yes
What would earth be like if it was closer to the sun?
Warmer
What will happen if the sun came hurling against Earth?
The Earth would be completely destroyed. However, everything and everyone would burn up before the Earth ever contacted the sun. Also, the sun would not "come hurling against the Earth" for any reason. The the Earth could possibly be pulled closer into orbit with the sun, at which point many animals and plant species would immediately go extinct, depending on how much closer Earth got to the sun (AUs)
What if the Earth changed its orbit and became closer or further away from the Sun?
if the earth came closer to earth all the waters would boil up and kill everyone, if the earth was further away, the water would freeze and all life would die
What would happen if the sun orbits like the earth?
the sun moves closer to earth
What would happen if the Sun came closer to Earth?
It would get to hot. We would die.
