Zero. "Second" is a unit of time, whereas "light year" is a unit of distance.The question is equivalent to asking: "How many days in a mile ?"
The speed of light is 186,282 miles per second.
1 light year = 9.4605284 × 1015 meters
31556926 seconds in a year
1 light year = 9.46 × 1018 millimetres
There are approximately 5.84 x 1012 (5,840,000,000,000) miles in one light year. This information is far from correct. There are 97,909,819,200 miles in a light year. Light travels 186,282 miles per second, & there are 525,600 is second in a year. 525,600 × 186282 = 97,909,818,200
A "light year" is the distance that light travels in one year. Light travels so fast that the speed of light is measured in miles per second or km per second. You probably already know how many seconds are in a minute (60), how many minutes are in an hour (60), how many hours are in a day (24), and how many days are in a year (365.24). So if you knew the speed of light, you could multiply all those numbers together and figure out how far light travels in a year. The speed of light is 186,000 miles per second or 300,00 kilometers per second.
No, that would be a light-second. A light year is the distance light travels in one year, which is 5,865,696,000,000 miles (5.87 trillion miles). Or 946,080,000,000,00 light travel 300,000 km per second
A light year is the distance traveled by light at a speed of 186,000 miles per second in a year. So the answer would be insignificant and hardly noticed.
light travels at 175000 miles per second divide 500million by 175000 and you will see how many seconds it takes a light year is 175000x seconds in a year try it
A light year is the distance that light can travel in a year.5,865,696,000,000 miles or 9,460,800,000,000 kilometresThis can be worked out because we know how far light travels in a second (186,000 miles per second / 300,000kilometers per second), we can therefore use simple maths to work out the answer.186,000 miles/second x 60 seconds/minute x 60 minutes/hour x 24 hours/day x 365 days/year = 5,865,696,000,000 miles/year.
The information about a light-year is not relevant to answer this particular question. To find out how far light goes (in a vacuum) in any specific time, simply multiply 300,000 (km/second) by the number of seconds.
It is hard to measure because light travels at such a high speed in one second that in one year, it would be too large a number to calculate. Try finding our the speed of light per second or minute and using conversions to calculate how many miles it would be. :)
A light year is the distance that light travels in a year, so it is a measure of distance, not time. Light travels at about 186,000 miles per second or about 300,000 kilometres per second. There are 31,536,000 seconds in a year. There is about 5,869,713,600,000 miles in a light year or about 9,445,950,434,500 kilometres.
Since light travels at about 300,000 kilometres per second, a light year is a very great distance.
-Light travels at 299,792,458 meters per second.-There is 31,556,926 seconds in one year.-Light travels 9,460,528,412,464,108 meters in one year and after doing the math, light travels 9,460,528,412,464.108 kilometers in one year.
The speed of light is 299,792,485 meters per second so if you travelled at this speed for a whole year that would be a light year.
