Let 'K' be the speed expressed in kilometers per hour. (1K kilometers/hour) x (1 light-year / 9.46073 x 1012 kilometer) x (1 hour / 60 minute) = ( 1.76167 x 10-15 K ) light-years per minute (rounded)

### Why do astronomers use light-years rather than kilometers or astronomical units to measure distance to stars and galaxies?

light years are a much more managable unit once you're talking distances of that scale. a light year is about 9.5X10^15 m. it's so much easier to use light years, especially when you're talking millions and billions of light years! but for calculations we don't use light years, it's just something that's easy to understand and compare.

### Why is an object 15 million light years away like looking at an object 15 million years ago?

Because you might have seen it in a telescope years ago idk Another Answer A light year is a measure of distance. If an object is 15 million light years away, the light you are looking at in this moment was produced 15 million years ago. If a star that far away went supernova at this moment, we wouldn't know it for another 15 million years. The light we see on the surface of our… Read More

### How many light years is the universe?

If one is assuming the Big Bang theory is in essence true, then one need only take the age of the Known Universe, and multiply by two. You see, the fastest that anything could have streaked out from the Big Bang is light speed, so if the Known Universe is 15 billion years old, then it would be 30 billion light years wide. The problem with that answer is that it ignores the expansion of… Read More
