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. New Horizons is covering about 3.9 AU's per year. Well, things wouldn’t be all that much better. Interstellar travel is the hypothetical travel by interstellar probes between stars or planetary systems in a galaxy. Very good question. Estimate: Light will travel 5,874,601,673,407.3 miles in one year. Add your answer and earn points. Travelling at the speed of the Helios Probe it would take 4,272 years to travel just 1 light years. 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. In other words, it takes light roughly four hours to get from the sun to Neptune. 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… 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). How Long Would It Take To Walk A Light-Year? > 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? I read an article stating a spacecraft traveling 38000 miles an hour would take approximately 80,000 years to travel 1 light year. 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. My estimates would be at around 40 years. Even if we were able to travel at the speed of light, it would still take us 1,400 years to get there. So, whatever your MPH speed is gonna be, use that to determine time. 2 0. How long to travel to Alpha Centauri? 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 … And how long would it take for a flight to it. For us on Earth, about 2000 years would pass, but for those making the trip, how much time would elapse for them? This question was originally answered on Quora by Jack Fraser. 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. Assuming you are in our fastest spacecraft as of now which has a speed of 17,500 mph 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. But seriously, distance and time are only relative to one another. If this is accurate, it will take … It would be more feasible to use an Ion Propulsion Engine to travel a light year, though. At 100MPH it takes 36 seconds to travel one mile. Which means it would travel 157,680,000 miles per year. 4 Answers. 1 decade ago. so that multiplied by the number of light years is our total How Long would it take to travel a Light Year In a space shuttle? Thus a light year is a measurement of distance traveled by light in the course of 1 earth year, IN A VACUUM!. It would still take much longer than a lifetime. 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. Answer Save. Also could you provide formula to your solution. 876000000 mpy is how fast you're traveling so divide 5865696000000 by that. this is because the length of objects around you become shorter as you travel closer to the speed of light. How to solve: How Long would it take to travel a light year at one-tenth the speed of light? The exact speed is 299,792,458 m/s (meters per second) or 186,00 mps (miles per second). Posted by Deborah Byrd in Space | May 16, 2017. now how many miles are in a light year? at the speed of sound _430.29 m/s, 1549. kph it would take 697204 years to travel one light year.

Anonymous. the answer to that is 5865696000000. well we have it all converted to years and miles so we are pretty much there. The proper definition of a light-year would be "the distance light travels in a year". Unless you were traveling at very close to the speed of light, it would take you centuries to travel that far. See answer GrcC8ookwo8ris is waiting for your help. 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. No, this isn't a trick question, but many people might think so. But it depends on the medium how much distance is in fact covered in a lightyear. The distances between stars are vast, which is why star travel is so far. 6696 is how long it would take to travel 1 light year. ", you can say, "that's about 53 lightmicroseconds. One light year is just a little less than 6 trillion miles. Lv 7. 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. A light year is almost 6 trillion miles. Here’s my answer: I asked the exact same question to myself a long time ago. If something is travelling at less than the speed of light, it will take longer than an earth year. so it would take us about 3,000 years to travel one light year. This table is a quick summary: If you burn about 80 calories per mile walked, you’d need two trillion PowerBars to fuel the trip. It is probably impossible to travel faster than the speed of light. How long would a 2000 light-year voyage would take if we are to travel at 99.9% the speed of light? You can really impress your friends with this information. Light travels at 300,000km/second. If your traveling at the speed it would take 1 year! Fuel is not a problem with interstellar travel, since we use Newton's First Law of Motion when travelling in space. anything that travels close to the speed of light has a different time zone than people like us, standing still. Am I … 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.
