SOLAR SYSTEM

Detailed explanation-1: -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.

Detailed explanation-2: -Much like Earth, Mercury is a terrestrial planet, which means it is composed of silicate minerals and metals that are differentiated between a solid metal core and a silicate crust and mantle. For Mercury, the breakdown of these elements is higher than Earth.

Detailed explanation-3: -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.

Detailed explanation-4: -The research argues that Mercury’s proximity to the Sun’s strong magnetic field is what bolstered the density, mass, and iron content of the rocky planet’s core.]
