Basically, it moves at a speed of 299,792,458 meters per second (1080 million km/hour; 671 million mph), which works out to about 9,460.5 billion km (5,878.5 billion miles) per year. I read an article stating a spacecraft traveling 38000 miles an hour would take approximately 80,000 years to travel 1 light year. This calculation takes into account the speed of light, which travels at 299,792.458 kilometers per second in a vacuum. How long would it take to travel 1 light years? Take the Sun for example, it is the closest star to Earth and its light takes about 8.3 minutes to reach Earth and its inhabitants.

One light-year is about 6 trillion miles (9 trillion km). On a calm sea, with a clear sky and excellent visibility, an observer with 20/20 vision can spot an object just 8.7mm in size (or 1/30th of an inch) from a distance of 17.8km. In space, it is easier to measure distance with the help of light years. around the world. Therefore, it would take a photon of light (a particle of light) one year to travel the approximate 5.88 trillion miles in a vacuum that makes up one light year.

A light-year is the distance light travels in one Earth year. For example, the nearest star to us is about 4.3 light-years away. The baseline temperature of outer space is 2.7 kelvins (opens in new tab) minus 454.81 degrees Fahrenheit, or minus 270.45 degrees Celsius meaning it is barely above absolute zero, the point at which molecular motion stops. eiusmod tempor incididunt ut labore et dolore magna aliqua. To do so, you will need a speed of almost the speed of light, so in the reference frame of Earth, you will have spent just a tad more that 1000 yr to travel 1000 ly.

In one Earth year of, A light year is the distance that light travels in vacuum in one year, about 6 trillion miles or 10 trillion kilometers. Exploring the universe at the speed of a light year would significantly speed up the whole process, and we can only hope for that for now. If we say that the fastest possible speed humans can travel in space is 20,000 km/hr, then the speed of light is 54,000 times that speed. No. Space is very, very cold.
