It will take 1 year, as soon as you and Albert work out how to travel at the speed of light. ;)
Light travels 9,460,730,472,580.8 Km. in one year.
well it depends on what you are measuring your 'much' in. First thing is, a light year is a distance not a time. It is defined as the distance light would travel in the time of one human year. Now to define this: light travels at ~300000000ms-1 and there are 31536000s in one year, so light will travel: 300000000*31536000 = 9.5x1015 metres in one year (that is 95 followed by 14 zeros! so a long distance) so in 9.7 light years light will travel 9.2x1016 metres. Which is a very very long distance.
95,000,000,000km/ph/lt/yrs is the speed of light. It takes light that long for light to travel to earth in about 1 light year. 95,000,000,000km/ph/lt/yrs is the speed of light. It takes light that long for light to travel to earth in about 1 light year.
A light year is the distance that light can travel in a year.5,865,696,000,000 miles or 9,460,800,000,000 kilometresThis can be worked out because we know how far light travels in a second (186,000 miles per second / 300,000kilometers per second), we can therefore use simple maths to work out the answer.186,000 miles/second x 60 seconds/minute x 60 minutes/hour x 24 hours/day x 365 days/year = 5,865,696,000,000 miles/year.
a year
A lightyear is the distance that light can travel in one year.
If you are talking about an electromagnetic wave, it will travel a light-year per year. That's how the "light-year" is defined. The frequency (1400 MHz) is irrelevant in this case.
A lightyear is not a measure of time but a measure of length that light can travel in 1 year. It would take 28 years for light to travel a lightyear
Light takes about 8 minutes to travel from the sun to the earth.We have a misconception here, a light year is a unit of distance not time. This confusion is very common!
A light year is a unit of space, not time. It is the distance light travels in a year. Eris is far less than a light year away.
if you are going the speed of light, it would take 1 year.
What, walking, swimming? a long time. By definition one light year is how far LIGT travels in one year. That's 5.8 trillion miles, or 5,800,000,000,000!
Canis Major at 25,000 light years away a light year is equal to the time it takes light in one year to travel. Speed of light is roughly 671,000,000 mph.
There is currently no technology that would enable human astronauts, from NASA or from any other organization, to travel one light year. There are some theoretical proposals for ideas that might work, but nothing even on the horizon for now. we can travel in space ROUGHLY 30,000 mph...at that rate it would take us ROUGHLY 22,366 years to travel 1 light year
at the speed of sound, 768 mph, it would take 891,837 years.
im not sure about galaxy, but for light to reach our Earth from the sun it takes about 8 minutes
Approximately 4.3 years. The distance is 4.3 light-years; a light-year is the distance you can travel in a year, at the speed of light. Please note that current technology doesn't allow us to travel anywhere near the speed of light.
