No. Mars is about 1/2 the size of Earth and has just 1/10 the mass. A simple comparison is the relationship of a US half-dollar (Earth) to a US dime (Mars).


Size is in terms of diameter which is measured as miles and not square miles. Mars has a diameter of about 4,222 miles whereas Earth has a diameter of 7962 miles .


one year on mars is equivalent to 780 earth days


Mars is approximately half the size of the Earth.


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


It is estimated that about 1.3 million planets the size of Mars could fit inside the sun. By comparison about one million planets the size of earth could fit in the sun.


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)


Mars is smaller than Earth.


Yes, Mars is almost exactly half the size of Earth as it is 0.533 times the size.


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


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.


Earth is roughly twice the size of Mars.


mars is smaller in volume than earth


Yes, Mars is about half the size of Earth


Earth is roughly twice the size of Mars.


Smaller, Mars is about half the size of Earth

The planet Mars is smaller than the Earth. It is also smaller than the planet Venus, which is the planet that is closest in size to the Earth (but like Mars, Venus is smaller than the Earth).


No, Mars is smaller than Earth. Earth is approximatley 12,750 kilometers in diameter. Mars is approximately 6800.


No, Mars isn't twice the size of the Earth. The equatorial diameter of the Earth is 7,926 mi (12,760 km), while the equatorial diameter of Mars is 4,220 mi (6,792 km). So we can tell that the Earth is twice the size of Mars, not the other way round.


Mars takes 687 Earth days to revolve around the Sun, so one Mars year is equivalent to 1.89 Earth years.


Venus has 1.79 times the surface area of Mars. Venus-12,104 km Mars-6,788 km


it's smaller than the Earth, about the size of Mars


Mars rotates on its axis once in 24.6229 hours, while Earth does that in 23.9345 hours. So Mars has a day about 30 minutes shorter than Earth.
