According to astronomer's measurement, besides the sun, our nearest star is the nearest neighbor star with 4.2 light years According to astronomer's measurement, our nearest star, except the sun, is a 4.2 light-year neighbor 1. Light year is a unit of length. How many meters is one light year equal to? 2. How many years will it take for an astronaut to leave the earth in a spaceship with a speed of 1000 meters per second? 3. What is the inspiration of the above calculation results for you to understand the universe

1. About 9.46 * 10 ^ 15m
2.1.26 * 10 ^ 6 years
3. The universe is too big, and the nearest star is so far away from us, so it's very difficult to make Star Trek

How many meters are 26.5 light years and 16 light years

The length that light years travel in a year is 300000 kilometers per second
26.5 light years = 26.5 * 365 * 24 * 3600 * 300000 * 1000M
You can calculate the rest by yourself

How many kilometers is one light year?

One light year = 3 * (10 ^ 8) * 365 * 24 * 60 * 60, approximately equal to
12 km of 9.5 * 10
A light year is the distance light travels in a year
The speed of light is 3 * 10 meters per second
365 * 24 * 60 * 60 seconds a year
Multiply the two into kilometers
