Mars is about twice as big as the Moon.
With a radius of 3396km, the planet Mars is about the same size as the inner and outer core of the earth (which is around 3490km radius in total).
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.
Mars has a diameter of roughly twice (2 times). This will give it a volume of approximately 8 times, larger. NB This is calculated by mathemtical ratios. Linear , A : B =(Diameter)Moon ; Mars = 1:2 Area , A^(2) : B^(2) Volume , A^(3) : B^(3) = Moon : Mars = 1^(3) : 2^(3) = 1 : 8
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, the moon and sun are not the same size. The sun is much larger than the moon.
No, the moon is not the same size as the sun. The sun is much larger than the moon.
no, say if you weighed 1kg on earth than you would weigh 0.1 on the moon and 0.3 on mars
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.
Earth is about 12,742 kilometers in diameter, so objects that are roughly the same size could have diameters within that range. Examples include Venus, Mars, and the Earth's moon, which all have diameters that are relatively close to that of Earth.
