Questions:

What is the distance of one light-year? Please define ly. What is light year meaning? What is one light-year? How much is a ly? How far is one light year? How long is 1 ly? Definition. How long to travel a light year? What is ly formula? How many kilometers in one light year?

Light year is a unit of distance. The unit is related to astronomy, astrophysics. Light year is the distance traveled by light in 1 year. Light photons travel at the speed of 300,000 km/sec in a vacuum. You will need 200 million years to walk 1 ly distance on foot.

1 year has 365 days,

300 000 kilometers per second * 60 seconds * 60 minutes *24 hours * 365 days = 9 460 800 000 000 kilometers.

Question:
What does the e mean?

Answer:
Mathematically the exponent e (or index or power) of a number 10 says how many times to use the number 10 in a multiplication. It means “times 10 to the power of”. Examples:

5.6e-2 = 5.6 * 10-2 = 5.6 * 0.01 = 0.056

1.1e-1 = 1.1 * 10-1 = 1.1*0.1 = 0.11

2e+6 would be a 2 followed by 6 zeros (2,000,000).

1.0e+0 = 1.0 * 100 = 1*1 = 1

1e+1 = 1 * 101 = 1*10 = 10

1.5e+2 = 1.5 * 102 = 1.5*100 = 100

an so on.

1.496e+8 = 1.496 * 108 = 1,496 * 100000000 = 149,600,000

One light year distance. How many kilometers in a light year?

One light year is equal to 9.460E+12 km, or 9 460 000 000 000 km.

I still dont understand How long does a light year travels ...

Guest: 2024-11-07 10:57:05

A light year is the distance light travels in a year, equal to 9,460,730,472,580.8 kilometers.

According to the International Astronomical Union (IAU) definition, a light year is equal to the distance that light travels in a vacuum, without the influence of gravitational fields, in one Julian year. This is the definition recommended for use in popular science literature.

Historically, a light year was defined as the distance that light travels in one tropical year, which refers to the time it takes for Earth to complete one full orbit around the Sun, based on the standards established in 1900. This measurement was primarily used in astronomy to express vast distances between celestial bodies.

A new definition for the light year has been introduced, which differs from the original one of the light year by approximately 0.002%. This small variation considers more precise measurements, but it does not matter. It represents our understanding of light and astronomical distances. It is important to note that the light year is generally not utilized in contexts requiring high levels of precision. As a result, for practical purposes, there is no significant difference between the old and new definitions of a light year, and both are commonly understood similarly within the scientific community.
