the speed of light is 3 x 108 meters per second or m/s.
Light takes 1 secs to travel = 3 x 108 meters
1 year = 365 days = 365 x 24 hours (8760 hours) =8760 x 60 mins ( 525600 mins)
= 525600 x 60 secs (31536000 secs)= 31536000 seconds.
Total distance in meters travelled by light in 1 year = 31536000 x 3 x 108 meters 94608 x 1011 meters95 x 108 Kms
I have done the calculations multiple times based on the fact the the speed of light is 300,000 km/s and have come to the conclution that light travles 9,467,280,000,000 km in one year. This is the distance of a light year
Second of the year * speed of light. = 31536000*300000 = 9460800000000km are there in a light year.
A very long distance - about 17,609,140,800,000,000 miles.
Tricky, but at a guess. 146,965,634,333,010,000 miles or about 147 quadrillion miles
Light will travel 2.562211 x 10*15 km. in 6500 years.
1 light year = 5,878,600,000,000 (5.8786 x 1013) miles (rounded)
25,000 light years = 146,965,000,000,000,000 (1.46965 x 1017) miles (rounded)
About eight minutes.
671,080,888 mph
Approx 59 ly.
Eris is far less than a light year away. Eris varies in distance between 99 and 37 astronomical units away, which works out to 0.00059 and .00156 light years.
There are many black holes in the universe .Scientists believe that there might be a black hole in the centre of our Milky Way galaxy which is about 25,000 light years from earth, and that that is why it rotates about its axis.
The figure isn't unanimously agreed. In a quick web search, we found estimates ranging between 315 and 525 light years.
10,700 million light-years.
