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.
No, Mars is actually smaller than Earth. But if the valles marineris was on Earth it would stretch across most of North America!
None, because only half an Earth can fit inside of Mars.
Earth is about 1.88 times larger than Mars.
Earth has the greater gravitational pull. Mars pulls with only about 38% of Earth's gravity.
Mars has roughly twice the Earth's period of revolution.

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.
Earth is about 1.88 times larger than Mars.
Earth has the greater gravitational pull. Mars pulls with only about 38% of Earth's gravity.
No it is the smallest
No, its smaller than the Earth.
Comparing diameters, Mars is about 53% the size of Earth. So, the volume of Mars is about 15% of Earth.
Mars is about twice as big as the Moon.
Actually, the answer is Mars. Mars' revolution is 1.88 years which is almost twice as the revolution of Earth.
Mars has roughly twice the Earth's period of revolution.
It takes mars twice as long to make a full revolution around the sun than it takes earth.
