5,878,489,000,000 miles (9,460,530,000,000 km)

Since light travels at a velocity of 186,171.1 mi/s (299,792.5 km/s), one light-year equals 5,878,489,000,000 miles (9,460,530,000,000 km).

orabout 6 trillion miles (10 trillion km)

A light-year is the distance light will travel in a year, orabout 6 trillion miles (10 trillion km).

about 6 trillion miles (9 trillion km)

Each light year is about 6 trillion miles (9 trillion km).

9.5 trillion kilometers

One light year equals 9.5 trillion kilometers, so while it may initially sound as if the end is nigh, scientists have stressed that there really is no cause for alarm over Earth's replotted proximity to Sagittarius A

10 trillion kilometers

(most stars are many light years away, and one light year equals 10 trillion kilometers or 6 trillion miles).

at a speed of 186,282 miles per second (299,792 kilometers per second

This is the distance light travels in one year at a speed of 186,282 miles per second (299,792 kilometers per second).

at an incredible speed of 300,000 kilometres a second

A light year shows the distance that light travels through a year, and travels at an incredible speed of 300,000 kilometres a second.

an amazing 5.9 Trillion miles

Light travels at an astounding186,000 miles per second, so in one light year, light would travel an amazing 5.9 Trillion miles.

5.88 trillion miles (9.46 trillion kilometers)

One light-year therefore equals 5.88 trillion miles (9.46 trillion kilometers).

light year

A light-year is the distance that light travels in one year, which is about 9.5 trillion kilometers.

5.88 trillion miles

For perspective, light travels 5.88 trillion miles in a year.

5 trillion, 865 billion, 696 million miles

In one year, light travels 5 trillion, 865 billion, 696 million miles.
