* The Sun's Life Cycle: The Sun is currently in the main sequence phase of its life, where it fuses hydrogen into helium in its core. This phase will last for approximately 10 billion years.
* Red Giant Phase: After the main sequence phase, the Sun will expand into a red giant, engulfing Mercury, Venus, and potentially Earth.
* White Dwarf Formation: After the red giant phase, the Sun will shed its outer layers, leaving behind a dense core called a white dwarf. This process will take several hundred million years.
The timeline:
* Current Age: 4.6 billion years old
* Main Sequence Phase: 10 billion years (approximately)
* Red Giant Phase: Several billion years
* White Dwarf Formation: Several hundred million years later
Therefore, the Sun is still billions of years away from becoming a white dwarf.
