What if Earth had two sun?

Answer 1

First off, it depends on where they are. We would have a much shorter night, or none at all. The earth would stay hot, and the winters would be shorter and warmer.

Answer 2

About half of the stars in the Universe are non-singles...
That is to say, more than half of them are Doubles, Triples, or Clusters. Doubles are usually called Binary Stars.

First off, were our Sun not a single star, and actually a Binary Star, then our orbit around the pair would be greatly confused, even irregular. Since our planet is only one of several orbiting the Sun, the orbits of those planets would also be greatly confused, even irregular.

Second, the location of the Earth some 93,000,000 Miles from the Sun gives us a specific amount of heat and illumination. Were the amount of heat and illumination (not to mention X Rays and Gamma Rays) would be greatly magnified. At present there is all manner of concern in the news about a warming of just one or two degrees F. Were
our heat and light to be from two sources you should imagine a cook, scortched, burned out rock in place of the lush green planet you now see.

Thirdly, I strongly suspect that the irregularity in gravitational pull from a binary star would have upset all possible stable orbits of objects around the central point and caused the objects to fall into the center of the binary pair (destruction of all objects). Photos of binaries sucking materials out of space objects may be found by doing a search using the key words:

Curious About Astronomy

to get over to a site created by Cornell University for interested people such as yourself. Once there look for info
on stars, and binary stars. You will be impressed with the info on this site.

Answer 3

This hypothetical statement has two answers, depending on how earth's orbit was in relationship to the binary.

A) If earth orbited BOTH stars(like they were 1 star),for life as we know it was to survive, it would have to be MUCH farther from the suns. The orbit of earth would likely be a little different

B) If earth orbited ONE star and passed by another, life as we know it would never evolve because earth would be in a perpetual noon and WAY too hot.

If you want a diagram, e-mail me through YahooAnswers, I'll give you my e-mail and attach an image showing the orbit paths of options A and B

Answer 4

It defnately would mess up or 24 hour day let alone the size of a year, but depending on the position of the new sun man kind would most likely survive and adapt.

Answer 5

earth would be a much hotter place and humans could never survive. If the sun was near pluto it wouldn't effect earth. but it would mess up our rotation.

Answer 6

if there were to be 2 suns and it was day time 24hours, then the world probably melt and be hot lava because it would keep on warming up and not losing enough heat because there would be no night time. we would all die (we wouldnt exist in the first place)

Answer 7

earth wouldn't be like it is today. a binary system would exert a gravitational pull into directions that more than likely would not even support a planetary body to rotate around it.
though not impossible, the variables would have to be so precise that it is mathematically impossible.

Answer 8

you would have a bright day 24 hours and day if you could tell the end.
