How long would it take to travel 1 light years?
about 37,200
Saying we were a space shuttle that travelled five miles per second, given that the speed of light travels at 186,282 miles per second, it would take about 37,200 human years to travel one light year.
How long does it take to travel 1 light year at the speed of light?
A light year is the distance that light travels in vacuum in one year, about 6 trillion miles or 10 trillion kilometers. One might therefore conclude that in order to travel one light year at one tenth the speed of light, this trip would take 10 years.
How long does it take reach Mars?
The trip to Mars will take about seven months and about 300 million miles (480 million kilometers). During that journey, engineers have several opportunities to adjust the spacecraft’s flight path, to make sure its speed and direction are best for arrival at Jezero Crater on Mars.
What is the speed of an astronaut in space?
According to “the internet”, the ISS (International Space Station) travels at around 7.66 km s so let’s assume the astronaut travels that fast, so we have our v. A rough approximation of c = 300,000 km s. So let’s work that out for a period of 1 year of space travel (which is roughly 3.154 × 107 seconds (that’s 31,540,000 seconds):
Do astronauts age slower in space?
So no matter the value of t, the amount of time the astronaut experiences, an observer would not see that the astronaut had aged at all. But keep in mind that the astronaut would experience time in what s/he considered normal! But perhaps an astronaut will age slower in space than on Earth.
Why do astronomers measure light-years?
Measuring in light-years also allows astronomers to determine how far back in time they are viewing. Because light takes time to travel to our eyes, everything we view in the night sky has already happened. In other words, when you observe something 1 light-year away, you see it as it appeared exactly one year ago.
How many miles does light travel in a year?
In a vacuum, light travels at 670,616,629 mph (1,079,252,849 km/h). To find the distance of a light-year, you multiply this speed by the number of hours in a year (8,766). The result: One light-year equals 5,878,625,370,000 miles (9.5 trillion km).
