If a light year takes light to travel a year...?

Question

Then how long would a light month/week/day be? Also how long does it take light to travel to earth?

I mean about how many miles is a light month/week/day. I already know how long a light year is. (A month counts as 30 days)

Answer 1

It takes like 1 second to travel 186,000 miles. So:

1 Light Minute = 11,160,000 Miles
8 Light Minutes = 89,280,000 Miles = 1 Astronomical Unit (AU) - This is the time it takes light to reach earth from the Sun. Used to measure relatively short distances in space.
1 Light Hour = 669,600,000 Miles
1 Light Day = 16,070,400,000 Miles
1 Light Week = 112,492,800,000 Miles
1 Light Month = 485,142,000,000 Miles
1 Light Year = 5,821,704,000,000 miles

Answer 2

well... a light year is more a term of distance. at 186,000 miles per second, you can do the math. so, a light month is still a month, but the light has only traveled for a month, so about a twelfth the distance of a light year. light from the sun hits earth in about 8 minutes... give er take a bit

Answer 3

The dimension "light Year"is a unit of astronomical distance which was invented by convenience and set by Astronomy.
It means if you multiply the travel time, in number of seconds in one year ,of light by "C"which is the velocity of light you obtain the distance to a particular celestial body in meters.
If the time the light travels in one month,week,day or hours you have to convert the time into seconds applied to the formula above in order to measure the distance in meters.
Light from the Sun is emitted radially as it moves orbiting the Galaxy.The rays to the Earth come at an angle depending which direction you are observing light. The ray would travel a distance of 498.3 light seconds from the Sun to a point on Earth.

Answer 4

The above answers are correct, here's some clarification.

A year is a unit of time, but a light year is a unit of distance - just like a meter or a mile. It is defined as the distance light travels in one year. Similarly, a "light minute" would be the distance light travels in one minute. You could create lots of possible unit combinations (eg, light weeks or sound minutes), but only light years are used in science.

Light travels at 299,800 kilometers per second (186,300 miles for the 3% of the world's population who doesn't use metric) in a vacuum, slightly slower in air or transparent liquids. A light second is therefore 299,800 kilometers. Just multiply the speed of light in km per second times the number of seconds in the time unit you want to get the distance for, such as a light minute or light month, etc.

For example, to find out how far one light year is, multiply 299,800 (km/hr) x 60 (sec/min) x 60 (min/hr) x 24 (hrs/day) x 365 (days/yr) and you get 9.46 x 10^12 km. There are 60 seconds in a minute, 3,600 seconds in an hour, 86,400 seconds in a day, 604,800 seconds in a week, 2,592,000 seconds in a 30 day month.....and you should be able to figure out the rest for yourself.

The exact time it takes for light to travel from the sun to the earth depends on whether we are at apogee or perigee, but the average distance between the sun and the earth is about 149 million km. At 299,800 km per second, that means it takes about 497 seconds, or 8.28 minutes.

Light reflected from the earth's moon takes about 1.26 seconds to reach the earth, not including the time it takes to get from the sun to the moon.

Light from the planets and stars takes a lot longer than 8 minutes - the edge of the universe is over 20 billion light years away - that's why astronomers use light years to measure great distances in space instead of meters or miles. Other distance units used by astronomers are parsecs (parallel seconds) and AU (astronomical units), and they are both based on known astronomical constants.

Answer 5

A light-year is a measure of distance NOT time. As is a light-month or a light-day.

A light-year or lightyear (symbol: ly) is a unit of measurement of length, specifically the distance light travels in a vacuum in one year. While there is no authoritative decision on which year is used, the IAU recommends the julian year.

Other units of measurement of distance used in astronomy are a parsec and an Astronomical Unit. Here are some conversion factors:

9.461×10^15 metres
9.461×10^12 kms
9.461×10^18 mm
94.607×10^24 Å

63.241×10^3 AU
3.26 parsecs

US customary / Imperial units
372.47×10^15 in
31.039×10^15 ft
10.346×10^15 yd
5.879×10^12 miles

So if a light-year is just under 6 trillion miles, a light-month must be just under half a trillion miles and a light day about 16.3 billion miles

It is about 40 light minutes from the Sun to Jupiter, 5.5 light hours to Pluto, 4.2 light years to the nearest star (Proxima Centauri) 10.5 light years to the nearest star with a planet (Epsilon Eridani) and 20.4 light years to the nearest star with an inhabitable planet (Gliese 581c).

Hope that helps put it all in perspective.

Answer 6

A light year, month or day essentially is the time it takes light to travel 1 year, month or day. Light travels about 300,000 kilometers a second so in a 24 hour period or 1 day light would travel 2,592,000,000,000 kilometers. Just keep multiplying it out to get to a month or year.

Answer 7

You seem to be pretty much hopelessly loconfused by the concept(s) of speed, distance, and time.

A light year is the distance that light travels in one years time.
A light month/week/day would be defined the same way.

The time it takes for light to travel to the Earth depends on where it's starting from.

Answer 8

i dont know the first part of the question but it takes like 8 minutes for light to travel from the sun to earth.

Answer 9

a light month is a distance. it's how far light can travel in a month. it's pretty far. a light minute is how far light can travel in a minute. they say it takes 8 minutes for light to reach us from the sun. therefore, the sun is 8 light minutes away from earth.

Answer 10

What direction? alongside the sting or around the diagonal? And is the quantity you're conversing of cube formed or another shape? a delicate 300 and sixty 5 days is a level of distance, so it incredibly is attainable to have a volume measured in cubic gentle years (whether a wierd ingredient to do). yet you provide the quantity; no longer the size. A volume of one cubic gentle 300 and sixty 5 days would desire to be bounded by making use of a cube one million gentle 300 and sixty 5 days on the two section. it could have one section equivalent to 0.5 gentle years, a component equivalent to a minimum of one gentle 300 and sixty 5 days, a component equivalent to 2 gentle years (extra like an oblong field than a cube). If the quantity have been cube formed (one gentle 300 and sixty 5 days on the two section), it would take one gentle 300 and sixty 5 days to pass parallel to between the aspects. it would take one million.seventy 3 years to pass from one nook to the choice nook of the cube. you could desire to arise with a brilliant number of different valid solutions reckoning on the form of the quantity (the 0.5, one million, 2 shape might take one million/2 a 300 and sixty 5 days at minimum and a pair of.34 years max). In different words, you do no longer provide sufficient counsel to respond to the two question.
