1 lightyear is about 9.5 million km.
Not true. 1 lightyear is about 9.5 x 10^12 km. that is 9.5 TRILLION km
I'll show you why: light moves at 3 x 10^8 m/s. meaning every second it will travel 300 thousand km. now there are 31 556 926 seconds in a year. So, 300 000 x 31 556 926 = 9.467 x 10^12 km
new answer;
9.46 trillion
I get 9,460,730,472,581 km

How many feet are in a light year?
2000000 ft
How many miles are there in 92000 kilometres?
There are 1.609344 kilometres in one mile. Therefore, rounded to two decimal places, 92000 kilometres is equal to 92000/1.609344 = 57166.15 miles.
Do Astronomers measure distances to stars in units called kilometers?
Well Yes, if you don't mind running into tons of 0s. A better way to measure it is using light years. It takes one year for a beam of light to travel 10,000,000,000 kilometers. A light year is 10 trillion kl.
What is the distance of proxima centauri to the earth?
Approximately 40.1 trillion kilometres. The distance of Proxima from here is 4.24 light-years. A (Julian) year is 3.15576 × 107 seconds, and the speed of light in vacuo is 2.997 924 58 × 108 metres per second. That makes a light-year 9.461 × 1015 metres. 4.24 times 9.461 × 1015 metres is 4.011 × 1016 metres, which is 4.011 × 1013 kilometres. Round to the number of significant figures in the least precise factor.
How many miles are there in 3000 kilometres?
There are 1.609344 kilometres in one mile. Therefore, rounded to two decimal places, 3000 kilometres is equal to 3000/1.609344 = 1864.11 miles.
How many light years in a year?
The distance that light travels in a vacuum in 1 year; 5.88 trillion miles or 9.46 trillion kilometres.
How many miles in a light year-?
It is approximately 10 trillion kilometres (or about 6 trillion miles). As defined by the International Astronomical Union (IAU), a light-year is the distance that light travels in vacuum in one Julian year.
A sentence about light-year?
Since light travels at about 300,000 kilometres per second, a light year is a very great distance.
Discuss the use of the term light year in relation to space and astronomy?
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.
What is a light year a unit of how far is it?
A light year is a unit of length equal to just under 10 trillion kilometres.
How long is half a light year?
1 half light year = 2.93924991 × 1012 miles or 4.7302642 × 1012 kilometres
What is the light year of Venus's?
A light year is a distance, or the total distance a ray of light can travel in 1 year (light travels at 300,000,000m per second) to be accurate. When Venus is closest to earth, it is about 38 million kilometres away (0.000004017 light years). When Venus is furthest from earth, it is about 261 million kilometres away (0.000027588 light years).
What is the relation between light year and astronomical unit?
The astronomical unit is the average distance from the earth to the sun, and is 149 598 000 kilometres. A light year is the distance light will travel in a year, the speed of light is just under 300 000 kilometres per second, so light travels one astronomical unit in just over eight minutes. A light year is 9.46x1012 kilometres, or 63239.67 astronomical units.
How many kilomaters away from earth is magellanic cloud?
There are two Magellanic clouds at distances of 160,000 and 200,000 light-years from the Earth. 1 light year is 9.46073E12 kilometres.
What unit of mesurement represents the distance light travels in one year?
The distance a beam of light travels in one year in a vacuum is called a "light year". It is equivalent to just under 9.5 trillion kilometres.
How far away are light years?
A light year is a measurement of distance. It is the distance that light travels in a year. It usually measure the distance of things in space. One light year is about 5,869,713,600,000 miles or about 9,445,950,434,502 kilometres.
How far does light travel a 1000 year?
