Interesting fact: Mercury is the smallest planet in our solar system and has a surprisingly large iron core relative to its size.
The answer: Mercury has a mass of about 3.3 × 10^23 kilograms, which is roughly 0.055 times the mass of Earth.
Mercury is the closest planet to the Sun and the smallest in the solar system. Despite its small size, it has a dense iron core that makes up a significant portion of its mass. Mercury's mass affects its gravity and ability to retain a thin atmosphere. Studying Mercury provides insights into planetary formation and the effects of solar proximity.
