How much is 424 light years to an earth year?

Answer 1

Light Years isn't a time, it's a distance or a length.

1 Light year is the distance that light travels in one year.

That is = 9,460,730,472,580,800 metres (in one year)

= 9,460,730,472,580.8 kilometres (in one year)

Answer 2

It's the distance light will travel through space in 4.2 years if it doesn't bump into

anything and get absorbed.

Here are some rough numbers to put it in perspective, if that's even possible.

Each of these is rounded:

-- 24,691,000,000,000 miles (24,691 billion)

-- as far as 987,600,000 trips around the Earth

-- 103,700,000 times as far as the moon is from Earth

-- 265,000 times as far as the Earth is from the Sun

-- about 507,000 times as far as the nearest that Mars can ever get to Earth

-- If the average height of every human being presently alive on Earth is 5 feet,

and a lot of them get together and stand on each others' shoulders (to get into

space without a space-ship), it would only take 251 million people stacked up to

reach the Moon ... less than double the population of Russia. So they would begin

to think that this is a pretty easy way to go places, and they might decide to get a

lot more people together and go to some more exotic places. But they would soon

be disappointed.

If all of the 7 billion people presently living on Earth got together and got stacked

up on a Sunday afternoon, they would reach only 0.14 of the distance to Mars

when it's as near Earth as it can ever be, and only 0.07 of the distance to the Sun.

Regarding your 4.2 light years ... If all of the 7 billion of us couldn't find a few more

friends to join in, then in order to reach that distance, we would have to stack up

3.7 million times over.

Answer 3

• The distance to Proxima Centauri - our nearest star (apart from the Sun)
• 265,606 AU
• 3.97342193 × 1013 kilometres
• 2.46896992 × 1013 miles
• 1.30361612 × 1017 feet
• 1.56433934 × 1018 inches
• 3.97342193 × 1018 centimetres

Answer 4

One light-year equals the distance light travels on one year. Since the speed of light is 299 792 458 meter per second, a light-year in vacuum is 9 454 254 955 488 000 m.

m/s = 31536000(60*60*24*365) m/year

Since the middel distance to the moon is 384 390 km, it takes the light 1.3 sec from the earth to the moon.

t = s/v => 3.84e+008 / 2.99e+008 = 1.3 sec

4.3 light year in vacuum is: 9 454 254 955 488 000 m * 4.3 = 4.065329631e+016 m (SI unit)

= 2.35e+013 miles

Answer 5

Let's clear something up: a "Lightyear" is a measure of DISTANCE (about 9.46 trillion kilometers), not time. If you're a photon, 424 light years is 424 times further than you can travel in a vacuum in one Earth year, but other than in ways similar to that it isn't meaningful to compare distances with times.

You've basically done the equivalent of asking "How tall is green?" There may be a context in which the question is reasonable (for example, if you have dowel rods that are color-coded by length), but without supplying that context it's pretty much nonsense.

Answer 6

1 light year is the distance traveled by light in a full year.

So 4 light years is the distance that light travels in 4 years.

If something is 4 light years away from the earth, the light will take 4 years to reach us.

Answer 7

It is how far light travels in 4.2 years (about 2.469*10^13 miles (1 light year is equivalent to about 5.879*10^13 miles)).

Answer 8

4.3 Parsecs = 14.0250359 light years

Answer 9

I'm not sure how long it would take the star to get here,

but the light that shines from it takes 4.4 years.

Answer 10

4 light years is the distance that light travels through vacuum

during a time interval of four years.

In rounded numbers, it's roughly 23,514,800,000,000 miles.
