Sun vs. Moon: What's the Difference?
By Janet White || Published on December 2, 2023
The Sun is a star at the center of our solar system providing light and heat, while the Moon is Earth's natural satellite reflecting the Sun's light.
Key Differences
The Sun is a massive, luminous sphere of plasma, a star that is the primary source of light and heat for the planets in the solar system. In contrast, the Moon is a solid, rocky body orbiting Earth, illuminated by the Sun's light.
The Sun’s surface, known as the photosphere, is where light is emitted, making it visible from Earth. However, the Moon's surface, covered in craters, mountains, and lava plains, reflects the sunlight, making it visible in our night sky.
The Sun is essential for Earth’s climate and weather, influencing life through its energy. Whereas, the Moon affects Earth by causing tides, stabilizing the planet's rotation, and influencing various biological rhythms.
In terms of size and composition, the Sun, composed primarily of hydrogen and helium, dwarfs the Moon, which is made up of silicate rock. The Sun's immense gravity holds the solar system together, while the Moon's weaker gravity affects Earth's tides.
Culturally, the Sun has been worshipped in many societies as a life-giving deity, symbolizing power and energy. The Moon has often been associated with mystery and romance, influencing various aspects of culture, including calendar systems and mythology.
