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.
An astronomical unit (A.U.) is the average distance between the Earth and the Sun, which is about 93 million miles or 150 million kilometers. Astronomical units are usually used to measure distances within our solar system.he speed of light is about 186,000 miles or 300,000 kilometers per second. So, in one year light travels a distance of about 5,880,000,000,000 miles or 9,460,000,000,000 kilometers or 63,240 A.U.. This distance is 1 light-year.
