关于 天文单位 (au)
Originally based on Earth's mean distance from the Sun, the astronomical unit (AU) was fixed in 2012 at exactly 149,597,870,700 meters. Planetary scientists use AUs to express distances within the solar system: Mars orbits at about 1.52 AU, Jupiter at 5.2 AU, and the outer edge of the Kuiper Belt at roughly 50 AU.
关于 秒差距 (pc) (pc)
Approximately 3.26 light-years (30.857 trillion km), the parsec is defined as the distance at which one astronomical unit subtends one arcsecond of parallax. Professional astronomers prefer parsecs over light-years because parsecs relate directly to the trigonometric parallax method used to measure stellar distances.
