Mercury
Mars is about half the size of Earth in terms of diameter.
That depends what you mean by "size". Diameter: 0.38 times the diameter of Earth. Radius: same number, since the radius is half the diameter. Volume: the ratio of the diameters cubed. Mass: 0.055 times Earth's mass.
Mercury is larger than the moon and so is closer in size to Earth than the moon is. It should be noted that Mercury is closer in size to the moon than it is to Earth.
The diameter of Mercury is 4,879 kilometers, which is about 38 percent of Earth's diameter. Earth is about three times the size of Mercury.
Mercury is larger. size of Mercury: 4879 km size of Earth's Moon: 3475 km
The gravity on Mercury is about 38% of Earth's gravity, which means that objects weigh less on Mercury compared to Earth. This is due to Mercury's smaller size and mass compared to Earth.
