Elements that Construct the Sun, Earth, and Moon

☀️ Sun

• Hydrogen (~74%): Primary fuel for nuclear fusion.
• Helium (~24%): Fusion product, second most abundant.
• Trace elements: Oxygen, carbon, nitrogen, iron, neon, magnesium.

🌍 Earth

• Iron (~35%): Core composition.
• Oxygen (~30%): Found in silicate minerals and atmosphere.
• Silicon (~15%): Major crustal element.
• Magnesium (~13%): Mantle component.
• Other elements: Sulfur, nickel, calcium, aluminum.

🌙 Moon

• Oxygen (~43%): Bound in oxides and silicates.
• Silicon (~21%): Major crustal component.
• Magnesium (~19%): Present in lunar rocks.
• Iron (~10%): Found in basalts and core traces.
• Other elements: Calcium, aluminum, titanium.
