Space Distance Categories
Solar System
Distances within our solar system are typically measured in AUs. Earth is 1 AU from the Sun, while Neptune is about 30 AU away.
Interstellar Space
The closest star to our solar system, Proxima Centauri, is 4.24 light-years away. Interstellar distances are best expressed in light-years.
Galactic Scale
The Milky Way galaxy is approximately 100,000 light-years in diameter. At these scales, astronomers often use kiloparsecs (thousands of parsecs).
Pro Tip: When comparing cosmic objects, use the same unit of measurement for clearer understanding of relative distances.
Frequently Asked Questions
How accurate is this space unit converter?
Our converter uses precise astronomical constants and AI assistance to provide highly accurate conversions between all major space distance units.
Why do astronomers use different units for space?
Different units are practical at different scales. AUs work well within our solar system, while light-years and parsecs are better for interstellar and intergalactic distances.
What's the difference between a light-year and a parsec?
A light-year is the distance light travels in one year (about 9.46 trillion km). A parsec is based on stellar parallax and equals about 3.26 light-years.
