How long would it take to travel a light year? The distance of a light year. How long would it take the space shuttle to go one light-year? The shuttle orbits the Earth at about 5 miles per second (18,000 mph). Light travels at 186,000 miles per second, which is about 37,200 times faster than the shuttle. So the shuttle would need about 37,200 years to go one light-year.

According to astronomers what is a light year it is a math question? Light moves at a velocity of about 300,000 kilometers (km) each second. So in one year, it can travel about 10 trillion km. More p recisely, one light-year is equal to 9,500,000,000,000 kilometers.

How long would it take to travel a light year? A light year is 9.4605284 × 10^15 m, or 9.4605284 × 10^12 km. So it'd take you about 237123803 hours, which works out at 27069 years or over 27 millenia. And the nearest star to Earth is 4 light years away. This is why most scientists think we'll never achieve interstellar travel.

What is a light year? A light year is the distance that light can travel in a year, or: 186,000 miles/second * 60 seconds/minute * 60 minutes/hour * 24 hours/day * 365 days/year = 5,865,696,000,000 miles/year. A light year is 5,865,696,000,000 miles (9,460,800,000,000 kilometers). That's a long way! Using a light year as a distance measurement has another advantage -- it helps you determine age. Let's say that a star is 1 million light years away. The light from that star has traveled at the speed of light to reach us.

- But how far exactly is a light-year? Light travels 186,000 miles per second. There are 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day, and 365 days in a year. Multiply these together to get 31,500,000 seconds in a year.

Speed of light First of all, a light-year is the distance light travels in one year. The star Alpha Centauri is about 4 light-years away, so light from Alpha Centauri takes 4 years to get to the Earth. Now, if we wanted to travel to Alpha Centauri, we would have to know how fast our spaceship is travelling. The fastest rockets move at about 20,000 mph.

1 light year is equal to how many years of the Earth? Light travels at 300,000 kilometers per second, and the distance it travels in a single year is 9,460,730,472,580.8 kilometers. That’s a light year. So, for example, the star Alpha Centauri is 4.467 light years away from us, so a beam of light would take 4.467 years to get from Earth to Alpha Centauri.

- Therefore, a light second is 186,000 miles (300,000 kilometers). A light year is the distance that light can travel in a year, or: 186,000 miles/second * 60 seconds/minute * 60 minutes/hour * 24 hours/day * 365 days/year = 5,865,696,000,000 miles/year. A light year is 5,865,696,000,000 miles (9,460,800,000,000 kilometers).

What is a light year? ­So to measure really long distances, people use a unit called a light year. Light travels at 186,000 miles per second (300,000 kilometers per second). Therefore, a light second is 186,000 miles (300,000 kilometers).

Light-year A light-year is equal to 9,460,730,472,580.8 km (about 9.461 Pm; 5,878,625,373,183.61 statute miles; about 63,240 astronomical units or about 0.3066 parsecs. The exact length of the light-year depends on the length of the reference year used in the calculation, and there is no wide consensus on the reference to be used.

How long would it take to travel a light year? Light year is a unit of distance.The light travels 300,000 kil,ometer per second,the distance traveled by light in one year is called Light year. So if you travel at speed of light, it will take one year. Object with mass can never reach the sped of light.

How do you calculate a light year? One light year is the distance that light travels in one year. The speed of light is 186,000 miles per second, or 300,000 km per second. There are 60 seconds in a minute, and 60 minutes in an hour. There are 24 hours in a day and a year is 365.25 days long. So, multiply 186,000 times 60 times 60 times 24 times 365.25.

The Milky Way If Voyager were to travel to the center of our Galaxy, it would take more than 450,000,000 years to travel the 8 kpc. If it could travel at the speed of light, an impossibility due to Special Relativity, it would still take over 26,000 years to arrive!

How Far Does Light Travel in a Year? As a result, looking at objects billions of light-years from Earth is to see billions of light-years back in time. Yes, light travels at an extremely fast speed. But given the sheer size and scale of the Universe, it can still take billions of years from certain points in the Universe to reach us here on Earth. Hence why knowing how long it takes for light to travel a single year is so useful to scientists.

- Radio signals that carry the data travel at the speed of light which is about 300,000 kilometers per second. At this speed, the signals can reach Earth in as little as 4 minutes (78 million km), or can take as long as 21 minutes (377 million km). Engineers refer to this length of time as the one-way light time..urveyor will take 309 days to reach Mars. In theory, the ideal transit time is 259 days. However, the journey can take anywhere between seven to 10 months depending on type of trajectory chosen and the precise locations of Earth and Mars at the time of launch.

How long does it take to travel 500 light years? Light travels at a speed of 1.08*10^9 km/h. Therefore light travels at a speed of approximately 17,647 times faster than Voyager 1. 17,687*500 = 8.8 million years. It would take modern technology's most successful space probe 8.8 million years to reach Kelper 186.

- by John Carl Villanueva on September 10, 2009. 1 light year is the distance light can travel in vacuum in one year’s time. This distance is equivalent to roughly 9,461,000,000,000 km or 5,878,000,000,000 miles.This is such a large distance. For comparison, consider the circumference of the Earth when measured at the equator: 40,075 km.This visible-light image shows the galaxy dubbed UGC 3789, which is 160 million light-years from Earth.hat assignment is given to the parsec. 1 parsec is approximately equal to 3.26 light years. Another commonly used unit of distance is the astronomical unit or AU, wherein 1 AU is the average distance between the Earth and the Sun, and is roughly equivalent to 150,000,000 km.

Speed of light A light year is the distance light travels in one year. That distance is 5,900,000,000,000 miles. That’s right, five trillion, nine hundred billion miles that light travels in one year. It is often rounded up to 6 trillion miles in a year or that a light year equals a distance of 6 trillion miles.
