What is the value of one light year anyone please tell me |
| Answer» A\xa0light-year\xa0is the distance\xa0light\xa0travels in\xa0one year. How far is that? Multiply the number of seconds in\xa0one year\xa0by the number of miles or kilometers that\xa0light\xa0travels in\xa0one\xa0second, and there you have it:\xa0one light-year. It\'s about 5.88 trillion miles (9.5 trillion km).\xa0It is\xa0the\xa0distance that\xa0light\xa0can travel\xa0in\xa0one\xa0year.\xa0Light\xa0moves at\xa0a\xa0velocity of about 300,000 kilometers (km) each second. So\xa0in\xa0one\xa0year, it can travel about 10 trillion km. More p recisely, one\xa0light-year\xa0is equal to 9,500,000,000,000 kilometers. | |
