# What is the mass and density of Mercury?

## What is the mass and density of Mercury?

The mass and volume of Mercury is only about 0.055 times that of Earth. But because Mercury’s small mass is enclosed inside of a tiny body, the planet is the second densest in the solar system, weighing in at 5.427 grams per cubic centimeter, or 98 percent of the density of our planet.

Is Mercury a dense planet?

Structure. Mercury is the second densest planet, after Earth. It has a large metallic core with a radius of about 1,289 miles (2,074 kilometers), about 85 percent of the planet’s radius.

### What is the density of each planet?

Saturn is mainly composed of the lightest two gases known, hydrogen and helium. It is the only planet in our solar system whose density is less than water….Planetary Densities.

Planet Average Density (gm/cm3) Required Mass for 70 cm3 (gm)

How do you find the density of mercury?

(Atomic mass of mercury = 200) Hint: Density is defined as mass of a unit volume of a material substance. The density formula is d = M / V, where d is density, M is mass, and the volume is V.

#### What is the mass of planet Mercury?

Why is Mercury less dense than Earth?

Compared to Earth, Mercury is much smaller, which is why it inner regions are subject to less in the way of compression. Therefore, its high density is believed to be the result of a large, and iron-rich core.

What is Mercury density?

Mercury is a very dense, heavy, silver-white metal that is a liquid at room temperature. (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.

### What planets are smaller then Mercury?

Planet takes a mere 13 days to orbit its star. Exoplanets in the Kepler-37 system, compared with Solar System bodies. The smallest of the planets, Kepler-37b, is only slightly larger than the Moon, and noticeably smaller than Mercury. What’s the smallest exoplanet we can detect from Earth?

Does the planet Mercury have a smaller mass than Earth?

While both are terrestrial in nature, Mercury is significantly smaller and less massive than Earth, though it has a similar density. Mercury’s composition is also much more metallic than that of Earth, and its 3:2 orbital resonance results in a single day being twice as long as a year.

#### What planet is more dense mercury or Venus and why?

Mercury is the only other planet that has a density similar to Earth’s. Venus is the only planet which is similar in more ways then one. Because of this, Venus has been referred to as Earth’s twin. The diameter of Venus is 7,521 miles or 12,104 kilometers. This is close to the 7,926 miles or 12,756 km diameter of the Earth. Venus’ mass is roughly 80 percent that of Earth’s. 95% of Earth’s density is the density of Venus.
