Why is the AU impractical for measuring the distance to Alpha Centauri?
Answer
The calculation results in a very large number (hundreds of thousands of AUs), making light-years or parsecs more manageable.
For interstellar distances, converting the distance to AUs yields huge numbers, which is why astronomers switch to larger scales like light-years or parsecs for conceptual clarity.
