# how long would it take to travel a light year

anything that travels close to the speed of light has a different time zone than people like us, standing still. How Long Would It Take To Walk A Light-Year? Thus a light year is a measurement of distance traveled by light in the course of 1 earth year, IN A VACUUM!. Even if we were able to travel at the speed of light, it would still take us 1,400 years to get there. Multiply the number of seconds in one year by the number of miles or kilometers that light travels in one second, and there you have it: one light-year… If you burn about 80 calories per mile walked, you’d need two trillion PowerBars to fuel the trip. Lv 7. Traveling at the speed of light, it would take approximately 40 years to reach TRAPPIST-1 (not taking relativity into account for simplicity’s sake), which, in cosmic terms, is a neighborly jaunt. 1 light-year = 63240 AU (astronomical units) 63 240 / 3.9 = 16,215.3846 New Horizons would take 16,215 years just to go one light Year. Estimate: Light will travel 5,874,601,673,407.3 miles in one year. Exactly how long is a light-year? At 100MPH it takes 36 seconds to travel one mile. 4 Answers. It is probably impossible to travel faster than the speed of light. The proper definition of a light-year would be "the distance light travels in a year". To figure out how long it would take to travel one light year is simply mulitply! As defined by the International Astronomical Union (IAU), a light-year is the distance that light travels in vacuum in one Julian year (365.25 days). But it depends on the medium how much distance is in fact covered in a lightyear. Unless you were traveling at very close to the speed of light, it would take you centuries to travel that far. 1 decade ago. If your traveling at the speed it would take 1 year! Using 110 years of Billboard chart data, designers have created a stunning and mesmerising website that reveals how long it would take popular tracks to travel through the universe. The distances between stars are vast, which is why star travel is so far. How Long would it take to travel a Light Year In a space shuttle? Solved: How long would it take to travel 500 light-years at the speed of light? This table is a quick summary: Assuming you are in our fastest spacecraft as of now which has a speed of 17,500 mph Light travels at 300,000km/second. at the speed of sound _430.29 m/s, 1549. kph it would take 697204 years to travel one light year. One light year is just a little less than 6 trillion miles. And how long would it take for a flight to it. Am I … How long would a 2000 light-year voyage would take if we are to travel at 99.9% the speed of light? A light year is almost 6 trillion miles. this is because the length of objects around you become shorter as you travel closer to the speed of light. The next time someone says, "Hey, I just rode my bike 10 miles! It is hard to get a good answer to this question, because warp is only very vaguely defined. But seriously, distance and time are only relative to one another. In other words, it takes light roughly four hours to get from the sun to Neptune. 1 decade ago. Interstellar travel is the hypothetical travel by interstellar probes between stars or planetary systems in a galaxy. I read an article stating a spacecraft traveling 38000 miles an hour would take approximately 80,000 years to travel 1 light year. 6696 is how long it would take to travel 1 light year. You can really impress your friends with this information. fswaahy fswaahy It depends on what speed you are going at. Darren. You can work it out from there, or you can estimate: A light year is about 6,000,000,000,000 miles, and 36 seconds is roughly half a minute, so it would take 3,000,000,000,000 minutes, divide by 60 to get hours then divide by 24 to get days, then divide by 365 to get years. For example, if you have to travel 100 miles, and your speed is constant at 50 mph, it will take two hours for you to get there. Anonymous. The light-year is a unit of length used to express astronomical distances and is equivalent to about 9.46 trillion kilometres (9.46 × 10 12 km) or 5.88 trillion miles (5.88 × 10 12 mi). If something is travelling at less than the speed of light, it will take longer than an earth year. This question was originally answered on Quora by Jack Fraser. Fuel is not a problem with interstellar travel, since we use Newton's First Law of Motion when travelling in space. that means for the challenger to travel one light year it would take 37,256 years for a man made machine to travel one light year. For us on Earth, about 2000 years would pass, but for those making the trip, how much time would elapse for them? You cannot actually reach the speed of light, but at near light speeds, the time dilation effects of special relativity would occur, and you could make the trip in a much shorter time - as measured by you. Interstellar travel would be much more difficult than interplanetary spaceflight.Whereas the distances between the planets in the Solar System are less than 30 astronomical units (AU), the distances between stars are typically hundreds of thousands of … Unlike what the phrase may suggest at first glance, light-year isn't a measure of time - it's a measure of distance. ", you can say, "that's about 53 lightmicroseconds. It would still take much longer than a lifetime. If the universe is 93 billion light years in diameter, how long would it take to travel end to end at light speed? Which means it would travel 157,680,000 miles per year. Here’s my answer: I asked the exact same question to myself a long time ago. It would take light 53 microseconds to go 10 miles." New Horizons is covering about 3.9 AU's per year. if you went 100 kph (kilometers per hour) it would take you 94608000000 hours or 10800000 years to go one light year. How long to travel to Alpha Centauri? How long would it take to travel one light year? My estimates would be at around 40 years. So, whatever your MPH speed is gonna be, use that to determine time. Nevertheless, the Helios Probe is the fastest object ever created by humans and it travels at approximately 252,792 kph (157,078 mph). Also could you provide formula to your solution. so that multiplied by the number of light years is our total Well, things wouldn’t be all that much better. so it would take us about 3,000 years to travel one light year. Travelling at the speed of the Helios Probe it would take 4,272 years to travel just 1 light years. Relevance. Posted by Deborah Byrd in Space | May 16, 2017. Add your answer and earn points. Answer Save. the speed of a vehicle in low earth orbit is about mach 25, even at this speed it would take 40,000 years to travel one light year. It would be more feasible to use an Ion Propulsion Engine to travel a light year, though. Very good question. well given the new photonic drive they've developed, and proven on small scale, they say we should get up to speeds of 100km/second. it takes light (travelling at the speed of light, in a vacuum) one earth year to travel a light year, this is where the name comes from. If light travels at 186,000 miles per hour and a star is 75,000 light years away how long would it take for the light from the star to reach us. > How long would it take to travel to a star 6 light years away, assuming constant 1g acceleration for first half, and 1g deceleration for last half? The exact speed is 299,792,458 m/s (meters per second) or 186,00 mps (miles per second). 40,000 years, give or take. It may take a photon 100 (light) years to escape the density of our sun, but then it travels 8 lightminutes to reach earth. the answer to that is 5865696000000. well we have it all converted to years and miles so we are pretty much there. If this is accurate, it will take … It take to travel on light year why looking at the stars is a look back the distance from earth to sun 15 astronomers measure large distances light sd to cross the y way What Is A Light Year Nasa E Place Science For KidsHow Long Would It Take To Walk A Light YearHow Long… Read More » How to solve: How Long would it take to travel a light year at one-tenth the speed of light? 876000000 mpy is how fast you're traveling so divide 5865696000000 by that. 2 0. for someone travelling .999 times the speed of light, they may feel like they approached a light year in much less than a year.
