Mars won't collide with the Earth, so it's kind of pointless to wonder what would happen if it did.
However, the last time a body the size of Mars hit the Earth, we got the Moon out of the deal ... if the Giant Impact hypothesis is correct, anyway. What more or less happened was that the Earth wound up with most of the metal "core" of both the proto-Earth and Theia (the name given to the Mars-sized colliding body), and quite a lot of lighter rock splashed rather spectacularly high and eventually re-coalesced into the Moon.
If something of any significant size does collide with Earth, we won't be here to worry about it. A body much smaller than Mars would be sufficient to completely wipe out all higher forms of life on the Earth. Bacteria might survive an impact with something say 20 miles across; it's not terribly likely that anything else would.
This is a bogus question; Mars will never get close to Earth.
There is a hoax e-mail going around that on August 27, Mars will "LOOK AS BIG AS THE FULL MOON!!!!!"
It's a lie. Mars will not be especially close to Earth in August, and will never appear bigger than a dot in the night sky.
Mars would undergo significant changes starting with a higher mean surface temperature. This would result in the melting of frozen carbon dioxide on the polar caps, resulting in a runaway green house effect. As the surface temperature warms, water ice on the caps will eventually melt too, giving mars a warmer and wetter climate similar to earths today. Unfortunately, due to the fact that Mars has no magnetic field to block solar winds, much of the water vapor will be lost into space.
Earth on the other hand would experience a decrease in global temperature. Much of the lost ice on both caps will be renewed, and sea levels would decrease to well below pre-industrial levels. Humans would still be able to live a reasonably comfortable life due to earths already abundant atmosphere of green house gases. However if the burning of fossil fuels continued, global warming would still occur and the earths temperature will continue to rise even in its new Martian orbit.
Other than that, the days will be less bright and years would be longer. The night sky would be slightly darker due to the absence of Venus' close proximity, however Jupiter would appear brighter.

What do you think but it will hit the moon probably because it is getting inches and inches away so the probability is about 100 out of 1,000,000. So the probability for earth 1000 out of 100,000,000,000,000,000,000 so don't worry!
If the sun will be close to earth, earth's temperature will increase. It will be too hot.
Earth would potentially burn up from being too close to the solar flares of which the sun radiates.
Some planets are too far from the Sun, and some are too close to the Sun, while planet Earth has the perfect spot for life.
Mercury does not have any air. It is too close to the sun to have the kind of atmosphere that we have on Earth.
Earth will no longer be protected from the rays of the sun, which mean that earth will then be too hot for anything to survive.

The earth will come to an end
The Earth is not too far and also not too close.
i think that the answer is the sun but if that is not right i hope i was close.
Because its just at the correct distance from the sun. Its neither too close to the sun nor its too far away from 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.
Too Close to the Sun was created in 2009.
No. Ison's orbit never brough it anywhere close to Earth. The comet distentegrated in November 2013 after passing too close to the sun.
The Earth is the only planet to have water in a liquid state because it is neither too close nor too far away from the sun. If it was too close, the sun's heat would vaporize the water . If it was too far away, the water would be frozen solid.
