will the earth gradually heat up fromm 2 many stars surrounding it?

Question

there are so many stars in the universe.. woudnt u think that gradually the light from the stars would reach the earth and would warm earth bit by bit

qjmox14x wat does this mean? It's been 4 and a half billion years?. and y would u ask another question on a question-->how long do you think it takes to heat a planet up??? nice 1

Answer 1

The Earth receive Galactic power of radiation from the Universe.The Amount of power density received excluding the Sun's radiation is 1.1 x10^-11 joules per seconds per steradians.
The Earth receives radiation from the Sun of aprox. 1380 joules per second per meter square.is being absorbed from the Sun .
So the heating of the Earth depends how much heat Energy is radiated on Earth from the Sun for a certain amount of specified time. The contribution of heat energy from the cosmos to Earth is very small compared to that of the Sun.

Answer 2

Since the earth is probably expanding, there is no chance of this happening. Everything in the universe is moving away from each other so far down the road in the future everything will just burn out and end. Besides the stars are millions and billions of light years away and it takes so long for their light/heat to hit the earth that many stars we see in the night sky may have actually exploded by now (but we are still seeing their light cause it takes so long to get there).

Answer 3

There is plenty of room between stars. The sky is dark at night BECAUSE there are so few stars in so much space.

By this theory, outer planets would be as warm as inner planets, which they are not. Mars is colder than any Earth winter. Saturn is so cold, methane and butane fall like rain on Saturn's moon Titan. To make these a liquid on Earth, it takes huge freezers.

Answer 4

It's been 4 and a half billion years. How long do you think it takes to heat a planet up??? No, distance stars are so far away their radiant heat has absolutely zero effect on our planet.

Answer 5

No, you can tell this isn't going to happen because:
1) it's dark at night, so at present the energy from all the stars is much less than the energy from the Sun, and
2) on average, the stars are moving away from us, due to the Hubble flow (which we can detect by spectroscopy), so in future the sky will be even darker than it is now.

Answer 6

The inverse square law says that as light and heat move away form their source, they become weaker. Stars are so far away that their heat is so amazingly weak that they don't have any effect on us, we're just too far away.

Also, we can't hold onto enough heat to cause damage- ti woudl simply radiate away. However, the sun will one day heat itslef up (as fusion processes continue it heats up), which will affect us. But not for billions of years.

Answer 7

When the solar system approaches the galactic center the earth will have been long ago been vaporized by the expanding sun.

Answer 8

nooo theres no way that would ever happen. not until earth was dead and had no life on it anyways. our closest star is the sun. we're not moving close enough to it for it to rapidly increase the temp of the earths surface

Answer 9

We don't even get 1/360 of the energy of the sun. Do the math as we don't get very much.

Answer 10

I would say there is a very good chance of it happening, as it appears starlight has already cooked your brain.....
