    Core Planet
Click For Summary
The core of a rocky planet, such as Earth, is significantly different from the Sun's core in several key aspects. The Sun's core is a vast, extremely hot, and dense plasma region primarily composed of hydrogen and helium, reaching temperatures of about 15 million degrees Celsius. In contrast, Earth's core is much smaller, composed mainly of iron and nickel, and exists in solid and liquid states at temperatures around 5,000 to 7,000 degrees Celsius. Additionally, the density of the Sun's core is far greater than that of Earth's core. These fundamental differences highlight the distinct nature of planetary and stellar cores.

Note temperature, density, size, and composition.
But other than that...

You would be hard pressed to find materials that differ more. The Sun's core is a huge, hot, super dense region of plasma made up mostly of hydrogen and helium. The Earth's core is a much smaller region made mostly of relatively cool metals in a solid or liquid state.

Thread 'Population 3 star (Pop III) candidate LAP1'

"Pop III stars are thought to be composed entirely of helium and hydrogen with trace amounts of lithium, the ingredients left over after the Big Bang. They formed early on, around 200 million years after the universe began. These stars are extremely rare because they died out long ago, although scientists have hoped that the faint light from these distant, ancient objects would be detectable. Previous Population III candidates have been ruled out because they didn't meet the three main...
