The average age of the surface of Venus has been determined primarily from the Magellan mission.
mostly rock and iron!!!!The surface of Mercury is most similar to the surface of the moon. Both are about the same age (very roughly) and both are covered with impact craters.
For every 100 pounds of a person's weight on Earth, he would weigh 37 pounds on Mercury. Every child is above average.
The question is inappropriate because the surface of Mercury is not unmapped!
the sun
Mercury has an average surface temperature (67°) closest to the Earths average surface temperature (14°C). The temperature on Mercury varies a lot though - you could argue that Mars is closer in temperature.
It is 3.7 ms^(-2)

Meteorites smash into Mercury's surface to be so rocky

Mercury does have a solid surface
Mercury is the liquid with the strongest surface tension.
the sun
At the surface of Mercury, it's about 0.38 times Earth's surface gravity.
