How many per sec are there in one light year?

How many per sec are there in one light year?

The more commonly used light-year is also currently defined to be equal to precisely 31,557,600 light-seconds, since the definition of a year is based on a Julian year (not the Gregorian year) of exactly 365.25 days, each of exactly 86400 SI seconds….

How many km does light travel a year?

Light-year is the distance light travels in one year. Light zips through interstellar space at 186,000 miles (300,000 kilometers) per second and 5.88 trillion miles (9.46 trillion kilometers) per year.

How long would it take to travel 93 billion light years?

How many years it takes light to travel x distance. It would take light 93 billion years to go 93 billion light years. But the universe will expand more during that time. The visible part of the universe is 93 ly in diameter.

How do you convert light year to megaparsec?

You can do the reverse unit conversion from light year to Mpc, or enter any two units below: The SI prefix “mega” represents a factor of 10 6, or in exponential notation, 1E6. So 1 megaparsec = 10 6 parsecs.

How do you convert km to light years?

The kilometre is unit of length in the metric system equivalent to one thousand metres. 1Km is equivalent to 0.6214 miles. Kilometers to Lightyears formula. ly =. km * 0.00000000000010570. Lightyears. A lightyear is the distance that light travels in one year.

How to convert Mly to kilometers (km)?

We need to convert the million light years (MLY) or the million parsecs (Mpc) to kilometers (km). 1 LY = 9.461 x 10 15 m = 9.461 x 10 12 km (Appendix 6 & 1 km = 10 3 m)

What is the length of 1 pc in miles?

The parsec (symbol pc) is a unit of length used in astronomy. It stands for “parallax of one arc second”, and is approximately 19,131,554,073,600 (19 trillion) miles. A light year, abbreviated ly, is the distance light travels in one year: roughly 9.46 × 1012 kilometres (9.46 petametres, or about 5.88 × 1012 (nearly six trillion) miles).
