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).


Comparing diameters, Mars is about 53% the size of Earth. So, the volume of Mars is about 15% of Earth.



This is a function of distance - an object appears smaller the further away it is. Although Jupiter is many times the size of Mars, the two planets appear to be about the same size because Jupiter is also much further away from Earth than Mars is.

Mars has a similar size to the Earth. There may be life on Mars. Actually, the Earth is almost twice the size of Mars (1.88 --> 1). Venus is much closer to the size of Earth (1.05 --> 1)

Earth is not smaller than Mars, Mars is about half the size of Earth which makes Mars is smaller than Earth


Mars' diameter is about half that of the Earth and it's mass is only 10% of the Earth's.The total surface area of Mars is about the same as the total land area of the Earth.


The size of Mars is similar to Earth's size, and its gravitational pull is about the same force of that of Earth. Mars has a layer of frozen liquid beneath its dusty orange surface. This liquid is believed to be the same liquid as Earth's water. Mars is also believed to possibly support living microbes like those on planet Earth.


because mars is a lot smaller than the earth (mars is about the same size as the earth) it is said that the interior of mars has cooled. Therefore convection of the asthenosphere is not possible and continental drift does not occur. We think the earth is headed in the same direction as mars and the earths interior will eventually cool to a solid.


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.


Earth is about twice the size of Mars. The radius from core to surface of Mars is 3396km whereas the radius from core to surface of Earth is 6371km.


Yes Mercury (smallest), Mars and Venus (nearly the same size asEarth).
