How far does light travel in 1 yr Miles and Km?

Answer 1

If you are asking how far light travels ( in a vacuum ) in a year...... it travels 9,460,730,472,580.8 km. at a speed of 299,792,458 metres/second.

Answer 2

In vacuum, light travels roughly 300,000 kilometers (186,000 miles) per second.

It keeps moving at that same speed second after second, as long as it doesn't run

into material that slows it down, like air, or something that soaks it up and stops it.

At that speed, light covers about 9,460,500,000,000,000 kilometers (5,878,500,000,000 miles)

in a year. Astronomers on earth have received light from distant objects that has been

traveling through space for 13,500,000,000 years before it hit the telescope.

Answer 3

The distance light travels in a year is about 9.5 x 1012 km. (9.5 million million kilometers).

Answer 4

In a year, light will travel 9.5 x 1012 km, or 9.5 x 1015 meters.

Answer 5

5.87849981 × 10^12 miles or 9.4605284 × 10^12 kilometers

Answer 6

5.87849981 × 1012 miles
