Mars has lost its molten core (and as a result, it's magnetic field), its liquid water, and most of its atmosphere. These may someday happen to Earth, though hopefully not for billions of years.

How does the curiosity not float away while on Mars?
Just like Earth's gravity holds you to Earth, and doesn't let you float away, Mars, too, has some gravity (less than Earth), which won't simply let objects float away into space.
Can Human goes to Mars and back to Earth?
We have the technology for it but there are too many other problems about going to mars
What planet is too cold for liquid?
Mars, because the warmest day on Mars is barely the coldest day on Earth.
Do aliens live on the planet mars?
No. There is no evidence of life on Mars.
How is planet earth better than living on planet mars?
On Earth their is water and oxygen which we need to live, but on planet Mars there isn't these things. Also planet Earth just the right distance from the sun so we arent too hot but arent too cold just the right temperature to survive, whereas Mars is too cold.
Why does carbon dioxide ice exists on mars and not on earth?
Mars is cold enough for carbon dioxide to solidify at its poles. Earth is too warm for dry ice.
Can aliens live on Venus?
No, Venus is too hot, acidic and the pressure is too great to support any form of life. There may be life however on Mars. Photos indicate that there was water on Mars and has 'greenary' on the poles. It is possible that Mars was once like Earth and over time became a desert like we are doing to the Earth at the moment. The Martians probably took refuge underground and are still there. Underground colonies may also exist from Martians on Earth - as suspected by some in Central America.
Why does Mars have crators?
Mars has craters because the atmosphere is too thin for meteors to burn up in, (as most do before they hit the earth). There are also craters on Mars, because there is almost no erosion on Mars, as there is on earth to cover up the evidence of impact.
Why is Mars too cold to live on?
It is farther away from the sun than Earth is.
What does mars Venus and earth have anything to do with the Goldilocks syndrome?
Goldilocks's porridge was not too hot, not too cold but just right. The Earth is not too hot (like Venus) and not too cold (like Mars), but just right. It isn't surprising because life developed on Earth so it got used to the conditions at an early stage.
Which planet do most known extrasolar planets least?
Mars The inner planets such as Mars, Earth or Mercury. these are too small to identify in other systems and too close to the star.
Is the orbit of Mars closer to Earth than the orbit of Venus?
No. The orbit of Venus is closer to Earth's orbit than the orbit of Mars, by an average of 38 million kilometers (Venus 108 million km, Earth 150 million km, Mars 230 million km)Mars is only the closest planet to Earth when Venus is on the opposite side of the Sun from Earth and Mars is on the same side as Earth and Mars is not too far ahead or behind the Earth in their orbits.It can be as long as an entire Earth year that Mars is not closer, and it will only be closer for less than 4 months at a time.
