Normally, the planet Mars is easily seen and recognized by its reddish color. But during certain points in Earth's orbit, Mars is nearly on the opposite side of the Sun from us, and it is not visible.
Mars passed behind the Sun in December 2008, and should become visible in the eastern sky just before sunrise sometime in mid April 2009.
Yes, it appears as bright reddish "star" to the unaided eye.
Yes, so long as it is not `behind` the sun in its orbit. It can be seen quite clearly in the night sky, it looks like a bright red star.
The naked eye means a human can look up and see Mars, with no telescope.
Yes. It can be seen without a telescope also.
Yes.
If there is, it wasn't built by human beings from the planet Earth, and none of our remote sensing robot machines that we've sent to Mars has seen it.
Earth and Mars
All of them. That's where they were discovered from. Only Neptune cannot be seen with the naked eye.
If you are asking how long it takes for Mars to rotate on its axis, then the answer is 24 hours and 37 minutes, slightly longer than an Earth day.
No, it does not. The earth has a moon, and Mars does not. It is earth's moon, earth and the sun that are involved in eclipses. All of them. Without a moon, Mars cannot experience an eclipse.
no Mars does not go through phases as seen from earth.
Yes. It can also be seen from Earth without one.
it is doubble the brightness
Mars.
Yes it can I believe it can be seen with your eyes. It can be seen in colour through a telescope.
Mars is tremendously farther away from the Earth than the moon is.
Mars.
Mars.
No. The Sun would appear to be about 40% smaller from Mars, because Mars is about 40% further away from the Sun than Earth is.
Mercury, Venus, Mars, Jupiter, and Saturn can be seen with the naked eye.

No, Jupiter can also be seen by the human eye on earth.
