Which planet in our solar system has the biggest solid core?
While Earth has the largest solid inner core, the planet with the biggest solid core overall is Mercury .
Εδώ είναι γιατί:
* Γη: Earth's solid inner core is about 1,220 kilometers (758 miles) in radius, made primarily of iron and nickel.
* υδράργυρος: Mercury has a massive solid core that makes up a whopping 85% of its radius. This core is likely composed of iron and sulfur, and it's about 3,600 kilometers (2,237 miles) across.
Therefore, even though Earth's inner core is denser and hotter, Mercury's core is significantly larger in volume.
