3.26 light years make 1 par sec.
The number of years in a second... by definition!
Rastaban is the second-brightest star in the constellation of Draco. It's estimated to be situated at a distance of about 380 light years from Earth.
The distance from the Moon to Earth is a little more than one light-SECOND, meaning it takes light a little over a second to travel that distance.
"How many light years does Dschubba have?" "How many light years does Dschubba have?"
I think what you are asking is how many hours it takes light to travel 310 light-years. If that is what you meant, then it takes light about 2,717,460 hours to travel 310 light-years. 310 x 365.25 x 24
They really are not comparable. Light travels 186,000 miles per second, and one AU is about 8.3 light-MINUTES. You can probably do the math, from minutes to hours to days to years as well as I can. Or, you could google "1000 light years in AU" and get the answer
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
The speed of light is 186,282 miles per second.
9.68 light years
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.
It takes light 40 years to travel a distance of 40 light years.
