A parasecond is actually the long name of a parsec. The name originated in 1913 when light years were being used to measure distances to far away stars. The numbers were getting too high so a scientist (not sure which one) suggested a new unit named a parasecond (shortened to parsec) by combining he two words "parallax" and "arcsecond". Hence why any star with a parallax angle of 1 arcsecond is one parsec away. 1 parsec is roughly 3 light years.

There are about 31.56 million seconds in a year. Since light travels at a speed of about 299,792 kilometers per second, there are roughly 9.461 trillion kilometers in one light year. So, there are 9.461 trillion light seconds in a light year.
In a vacuum, light would cover 11,176,900 miles in one minute. (rounded)

How many light seconds are there in a light minute?
60.
How many kilometers are in 8.7 light years?
The answer of this question is at the end of the next paragraph if you don't want to know how I got it. There are 60 seconds per minute, 60 minutes per hour, 24 hours per day, and 365 days per year. The speed of light is 186,000 miles per second. I'll show you the math that I did. 60 times 60 is 3,600. 3,600 is how many seconds are in an hour so multiply it by 24 to get how many seconds in a day which is 86,400 seconds. Then you would need to find out how many seconds are in a year so you multiply 86,400 by 365 and get, 31,536,000 seconds. Now that you know how many seconds are in a year all that has to be done is multiplying the speed of light by that number. 5,865,696,000,000 miles, or 5 trillion 865 billion 696 million miles are in 1 light-year. Since you want how many miles are in 8 light years you have to multiply 5,865,696,000,000 by 8. You get 46,925,568,000,000 miles.
How many years are in 1 light year?
9,460,730,472,580.8 km Light travels at 299,792.458 km/sec. There are 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day, and 365.24 days in a year. Multiply all those together to get the distance that light travels in one year.
How long is a light year what does a light year describe?
A light-year is the distance light can travel in one year. Light travels at 186,000 miles per second. Multiply that by 3600 seconds in an hour and then by 24 hours in a day and 365 days in a year and you will get the distance in one light-year.A light year is defined as 9,460,730,472,580,800 meters exactly, derivedfrom the distance that light travels in vacuum in one Julian year.
How many km would light travel in a minute?
-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.
How many seconds does a ray of light travel in a year?
There are only 31,536,000 seconds in a year. So, light can only travel for 31,536,000 in a year.
500 million miles is how many light years?
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
How many seconds in a ligth year?
None, since a light year is a measure of distance and not of time.
How many meters are there in 19.0 light -year?
Having "A light-year is the distance light (speed = 2.998 108 m/s) travels in one year," you will then find how many seconds are in a year (31,556,926 seconds), multiply that number by 19 (given). Once you get how many seconds total in 19 years (599,581,594 seconds in 19 years) you will then multiple that number times the speed (2.998 108 m/s).Final Answer: 1.798 x 10172med
How many days in one lightyears?
two different units of measure. It's like asking how many seconds in a mile.But there are 365.25 light days in a light year if you assume a day = 86,400 seconds and you use the Julian definition of a year.
How many seconds does light travel in one year?
Light travels 31,536,000 seconds in a year, just like, let's say, a snail that never stops creeping. But light travels farther than a snail does in the same time. For example, in a year, light travels 9,454,254,955,000 kilometers (5,874,601,673,000 miles).
How Many seconds in the year?
There are about 31.5 million seconds in a year.
How many seconds are a year?
1 year = 31,556,926 seconds
14890 light seconds are equal to how many minutes?
Light seconds is a distance not a time.
How many meters are there in twelve billion light year?
A light year is the distance light can travel in one year. Light travels at a speed of around 2.99*108 m/s. Multiplying that by the number of seconds in 12 years gives you 1.135*1017m.
How many seconds on a year?
1 year = 31,556,000 seconds (rounded)
How many light seconds are there in a light minute?
60.
