If my memory serves me correctly, and I hope it does, it would take man approx 1000 years to travel one light year. If I am wrong, I ask for somebody to please inform me as I would appreciate the correction.
Because measuring in miles or kilometres would yield HUGE numbers ! A light year is defined as the distance light takes to travel in a calendar year. Therefore, since light travels at 186282 miles a second - this distance is 5,874,589,152,000 miles !
It takes about 3 days to travel to the moon using current spacecraft technology.
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.
It would take roughly 0.06 seconds if you find it using the equation S=Vt xD(time = Distance / speed)
The velocity of light in vacuum is a universal constant. A light year is the distance travelled at that velocity in one year. To define a sound year it would be necessary to also specify the precise characteristics of material it is being propagated through. A vacuum won't do, since sound doesn't travel through a vacuum.
Using rockets and other types of spacecraft.
Gas is extracted using conventional methods.
With current technology, it would take NASA thousands of years to travel 600 light years using conventional spacecraft. The vast distance and limitations of our current propulsion systems make such a journey unfeasible in a reasonable timescale.

It consumes less electricity for the same Lux and hence is more economic.
A conventional question to help improve your vocabulary is to ask you to make a sentence using a word you have just learned.
Rockets are launched using jet propulsion because it follows Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. The exhaust expelled at high speed propels the rocket in the opposite direction. This allows the rocket to overcome Earth's gravity and achieve the necessary velocity to reach space.
According to Legend, Wan-hu, a civil servant of the Ming dynasty, try to attempt outer pace travel by using rockets on a chair.
Mordern day weapons are called conventional. :-]

The speed of light can be measured using a microwave by sending a microwave signal from one point to another and measuring the time it takes for the signal to travel. By knowing the distance between the two points and the time it takes for the signal to travel, the speed of light can be calculated using the formula speed distance/time.
