How long does it take to run 17 kilometers per second to cover 1 light year?

1 light-year = the distance traveled in 1 year at the speed of light.

1 year is equal to = 365 * 24 * 3600 = 31,536,000 seconds.

The speed of light is 300,000 kilometers per second.

So 1 light year = 31536000 * 300000 = 9460800000000 km.

So 9460800000000 km 17 km seconds = seconds.

Seconds = Year 17647 21 days, 11 hours, 2 minutes and 24 seconds.

So, 17 kilometers per second took about 1 light year in 17647, 21 days, 11 hours, 2 minutes and 24 seconds.

A light-year is a unit of length, not a unit of time! Light-years are generally used to calculate the distance between stars, which refers to the distance that light travels in a vacuum for one Julian year, which is calculated by time and velocity. The speed of light is 300,000 kilometers per second, so one light-year is 9,460 billion kilometers.

The speed of light is 300,000 kilometers per second.

300,000 divided by 17 is approximately equal to 17,647, so it's 17,647.

A light-year is the length of a year that light travels.

Looks like you're asking the Voyager probe, which takes more than 15,000 years to get out of the solar system.

One light year is 946,080,000 kilometers of road.

Light-years, a unit of length, refers to the distance that light travels in a year, which is about 9,460 billion kilometers (or 5,880 billion miles).

Light can travel 300,000 kilometers in one second, and light years are the astronomical unit of elongation, which is literal.

The distance traveled in a year by light in a year 365 days in a year and the road taken in one minute by light: 300,000 kilometers per second * 60 seconds = 18 million kilometers in one hour of light and the road done in one hour: 18 million kilometers * 60 minutes = 108,000 kilometers in a day of light

108,000 km * 24h = 2592,000 km in one year alone: 259,2000 km * 365 days = 946,080,000 km.

A light-year is not a unit of time, but a measure of the distance of cosmic objects. Due to the large distance between celestial bodies in the universe, the wild reeds encountered are calculated using light years. Light-year, which literally refers to the distance that light travels in a straight line in a vacuum, is calculated from time and the speed of light.

Definitions

The distance traveled by a photon in free space and at infinity from any gravitational or magnetic field in a Julian year (defined as a day).

Because the speed of light in a vacuum is 299,792,458 meters per second (exact), one light-year is equal to 9460730472580800 meters (exact), or miles, or nautical miles, or about meters or kilometers.

。The propagation speed of light (electromagnetic waves) in a vacuum, the accepted value is c=.

or exact value), which is one of the most important physical constants.

Light travels about 10,000 kilometers per second.

Light generally travels about 10,000 kilometers per second, which is the fastest speed in nature.

Light-years are the distance traveled by light in a year:Light travels 300,000 kilometers per second, there are 365 days in a year, there are 24 hours in a day, and there are 3,600 seconds in an hour, so one light year = 300,000 x 365 x 24 x 3,600 = 9,460 billion kilometers (approximately).

Definition of the speed of light:The speed at which light or electromagnetic waves propagate in a vacuum or medium.

Definition of the speed of light: c=299792458m/s

Calculated value of the speed of light: c

Note: Gamma rays are faster than the speed of light, and gamma rays are reflected more than 27 times in the mirror to exceed the speed of light, and have exceeded the speed of light in many instrumental measurements (the average of 100 gamma ray speed experiments is

Light generally travels about 10,000 kilometers per second, which is the fastest speed in nature. A light-year is the distance traveled by light in a year: light travels 300,000 kilometers per second (approximate value here), there are 365 days in a year, a day has 24 hours, and an hour is 3600 seconds, so one light-year = 300,000 x 365 x 24 x 3,600 = 9,460 billion kilometers (approximately).

Light travels 10,000 kilometers in one second.

That's about 300,000 kilometers per second.

Since the beginning of the 20th century, our theories have been subject to Einstein's limit to the speed of light, which is 186282 miles per second (about 300,000 kilometers per second).

Even if we accelerate the spacecraft to this speed, it will take nearly a decade for the backup oak to reach our nearest star system, Alpha Centauri (about light-years away) and back.

In addition, the spacecraft itself also needs to consider the energy limit imitation system. Therefore, it is necessary to break through the limits of the speed of light to achieve these goals. Scientists have carried out many related experiments, such as the experiment conducted by Lijunwang Wang of Princeton University in the United States in 2000 and the experiment conducted by German scientists in 2007.

Initially, scientists were convinced that no matter or information could break through the speed of light, but light pulses could. In a vacuum, pulses of light measured at different locations appear to propagate at an incredible speed. However, this speed still won't help us much in space travel.

The 2007 experiment is still controversial.

That's about 300,000 kilometers per second.

Einstein's verification of the speed of light is 186282 miles per second (about 300,000 kilometers per second).

1 light year is about a trillion kilometers. The light-year is a very commonly used unit of length in astronomy, and the light-year refers to the distance that light travels in a vacuum for one year, which is equivalent to the speed of light multiplied by one year, and the product of speed and time is the distance.

Introduction to Lightyear. The light-year is a very commonly used unit of length in astronomy, and the light-year is the distance that light travels in a vacuum for one year, which is equivalent to the speed of light multiplied by one year, and the product of speed and time is the distance, and 1 light-year is about a trillion kilometers.

1 light-year is very far away for us, but for the vast universe, this distance is close at hand, we are located 10,000 light-years away from the center of the Milky Way, the diameter of the Milky Way is 100,000 light-years, but the Milky Way is only one of the trillions of galaxies in the universe, and there are many galaxies that are very far away from us.

Although a light-year is a unit of length, it can also reflect time, because how many light-years away means how many years light travels in the universe. For example, it took 2.5 million years for the light emitted by the Andromeda Galaxy to reach the Earth, which means that we are now seeing the Andromeda Galaxy 2.5 million years ago.

A light-year is about a trillion kilometers. A light-year is a unit of measurement of distance that refers to the distance that light travels in a vacuum for a year at a speed of 299,792,458 meters per second. Therefore, it is more convenient and practical to measure the distance between celestial bodies in the universe by using light-year units.

Expanding: Light-years are used to measure distances far beyond the solar system, for example, our Milky Way is about 100,000 light-years in diameter. At this distance, it becomes very impractical to use other units of distance, such as kilometers or miles.

Secondly, light years can also be a convenient representation of the relationship between time and distance. For example, if a star is 10 light-years away from Earth, it will take 10 years for us to see its light reach our eyes. So what we're seeing is actually the light from 10 years ago, not the present.

Due to the very long distance, the use of light-year rocks as a unit of measurement for cosmology also has its limitations. While light-years are a convenient way to measure the distance between galaxies, for farther distances, such as the edge of the universe, we need to use more units to measure. In this case, astronomers use more advanced techniques, such as magnitude, redshift, and standard candle (a type of star that can determine the distance of a star), to help them determine the greater distance.

In short, one light-year is equivalent to about 10,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 Although the light-year has its limitations, it is still one of the most useful units in cosmological research. <>

To convert 17 meters per second into kilometers in hourly scale, you need to perform the following steps:

1.Convert 17 meters per second into meters per hour: 1 second = 1 3600 hours, so 1 second 17 meters of rapid leakage = 17 meters of seconds = (17*3600) meters of hours = 61200 meters of hours.

2.Convert the number of meters into kilometers: 1 kilometer mu is rotten = 1000 meters, so 61200 meters per hour = 61200 1000 = kilometers per hour.

Therefore, 17 meters per second is equivalent to kilometers per hour.

Light travels 299792458 meters per second, about 300,000 kilometers per second. The same is true for other media.
