Donât worry about it. 63% is no big deal and for 8 hours it is absolutely nothing. In fact, some folks like their cigars at 63% RH all the time. Your humidor will slowly return to a higher RH and if, after a few days, it doesnât then add some water to your humidifier.
A light-year (abbreviation: ly), sometimes written light year, is a unit of length used informally to express astronomical distances. It is approximately 9 trillion kilometres (or about 6 trillion miles). As defined by the International Astronomical Union (IAU), a light-year is the distance that light travels in vacuum in one Julian year. Because it includes the word year, the term light-year is sometimes misinterpreted as a unit of time.
So a light year is about (I've rounded off a bit) 5,878,786,100,000 miles. That's almost 6 trillion miles. The distance from the earth to the Sun is 93 million miles. The distance to the nearest star is 4.3 light years, and the distance to the Andromeda galaxy is 2 million light years.ating Newest Oldest. Best Answer: A light year is the distance that light travels in one year. The speed of light is 186,287.5 miles per second. You can find out the number of seconds in a year by multiplying the number of seconds in a minute (60) by the number of minutes in an hour (60).
