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.
It is so fast that light can travel about seven times around Earth in one second!! Thatâs about light. What is a light year then? Light Year is the distance that light can travel in one year. Considering that light can travel about 300,000 kilometers (km) each second, in one year, it can travel 9,500,000,000,000 kilometers. Phew! It would be easier to say that one light year is about 10 trillion km.
