AU Full Form In English
The full form of AU is “Astronomical Unit”. It is a unit of measurement used in astronomy to describe the average distance between the Earth and the Sun. One Astronomical Unit is approximately 149.6 million kilometers (92.96 million miles). AU is commonly used by astronomers to express distances within our solar system, making it easier to understand and compare vast spaces between planets, comets, and other celestial objects. Using AU simplifies calculations and communication in the field of space science.
AU Full Form In Hindi
AU का फुल फॉर्म “एस्ट्रोनॉमिकल यूनिट” है। यह खगोलशास्त्र में दूरी नापने की एक इकाई है, जिसका उपयोग पृथ्वी और सूर्य के बीच की औसत दूरी को व्यक्त करने के लिए किया जाता है। एक एस्ट्रोनॉमिकल यूनिट लगभग 1.496 करोड़ किलोमीटर (92.96 मिलियन मील) होती है। AU का उपयोग खगोलविदों द्वारा हमारे सौरमंडल के भीतर की दूरी को समझने और तुलना करने के लिए किया जाता है। इससे अंतरिक्ष विज्ञान में गणना और संचार सरल हो जाता है।
