What is Mercury’s mass and diameter?
Distance, Size and Mass Mercury has a radius of 2.439 km or 1516 mi, and a diameter of 4.879 km or 3.032 mi. It is about the size of the continental United States, slightly bigger. It has a mass of about 3.285 × 10^23 kg or about 5.5% that of Earth.
Is Mercury 1/3 the size of Earth?
With a radius of 1,516 miles (2,440 kilometers), Mercury is a little more than 1/3 the width of Earth. If Earth were the size of a nickel, Mercury would be about as big as a blueberry. From an average distance of 36 million miles (58 million kilometers), Mercury is 0.4 astronomical units away from the Sun.

What is the hottest planet?
Venus’ thick atmosphere traps heat creating a runaway greenhouse effect – making it the hottest planet in our solar system with surface temperatures hot enough to melt lead.
Can you see Mercury from Earth?

Why is Mercury so heavy?
(For more information about mercury, click here.) Mercury has a density of 13.5 g/mL, which is about 13.5 times denser than water (1.0 g/mL), so a small amount of mercury like this feels unexpectedly heavy. Mercury also has a very high surface tension, so small droplets of mercury form nearly spherical beads on glass.
Why is Mercury GREY?
Patches of a carbon-rich material called graphite — the same stuff that’s in a pencil — cover Mercury’s surface, tinting it dark gray. These patches are thought to come from an ancient carbon crust that’s been hiding underneath Mercury’s surface, a study published in Nature Geoscience says.
