Mars is about twice as big as the Moon.
Mars is bigger than the Moon, having about twice as much surface area as the Moon. Mars-6,788 km Moon-3,476 km
August the 27th of this year (2009) is when Mars is to be the closest it has ever been to the earth. It is supposedly to be about the same size in the sky as the moon.
probably ganymede, its the largest moon in the solar system (about the same size as mars) and it made up mainly of ice.
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, it is a hoax. Google "Mars size of moon".
The moon does; it causes the tides. Mars is just there ... without it Earth would be just the same.
No.
no, say if you weighed 1kg on earth than you would weigh 0.1 on the moon and 0.3 on mars
No. Mars and Earth never collided. Around 4.6 billion years ago another planet is believed to have collided with Earth, resulting in the formation of the moon. This planet, known as Theia, was probably about the same size as Mars.
Mars is about 80 million km away from the moon, the same (strangely enough) as the distance from Earth to Mars. So, not really. Although I guess it depends on your scale.
no
It depends what size you would call normal, but Mars is about the same size as Earth.
