WebAs such, one light-year is the equivalent to 9 trillion kilometers / 6 trillion miles, and our Universe is 93 billion light-years in diameter. That’s how big our Universe is, and that’s not even the end of it. The 93 billion years is just the observable Universe, the Universe, which we can currently see. WebOne light-year is defined as the distance traveled by light in one year. Also, speed is the distance traveled per unit of time. Thus, the distance traveled by light can be written as follows: Distance = Speed × Time ⇒ 1. 00 light - year = 2. 998 × 10 8 m s × 3. 16 × 10 7 s = 9. 47 × 10 15 m Thus, there are 9. 47 × 10 15 meters in 1.00 light-year.

How long does it take light to travel 1 million miles

Web- One Light-year o Noted 1 LY o Equals the distance that light travels in one year - Useful unit because o Light always travels at the same speed o Highest speed anything can travel through space o Makes for a good standard to keep tract of distances - Light travels 3 x 105 km/s (1 km = 0.6 mile). Speed of light - 3 x 105 km/s - 3 x 108 m/s Web1 Light years = 5878499814210 Miles. 10 Light years = 58784998142100 Miles. 2500 Light years = 1.4696249535525×1016 Miles. 2 Light years = 11756999628420 Miles. A light-year, alternatively spelled light year, is a large unit of length used to express astronomical distances and is equivalent to about 9.46 trillion kilometers (9.46×10 km), or 5.88 trillion miles (5.88×10 mi). As defined by the International Astronomical Union (IAU), a light-year is the distance that light travels in a vacuum in one Julian year (365.25 days). Because it includes the time-measurement word "year", the term light-year is sometimes misinterpreted as a unit of time. church of the holy sepulchre tomb
