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?"
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 answer to how many light years is M99 away from earth it is 25100 light years away!
9.68 light years
At the speed of light 1.5 million 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.
3.262 light years.
