It is the DISTANCE between earth and moon that governs the gravitational pull of EACH UPON THE OTHER. Since the moon's orbit around the earth is elliptical, the moon goes through perigee (its smallest distance to the earth) and apogee (its greatest distance) every month. Perigee and apogee can occur at any phase.
What is an Auction and how does it work? An Auction is where property is sold at a specific time and place to the highest bidder. Most auctions require a person to get a bidder number or other identifying item prior to bidding.
Think of an auction. The bid is the price closest to the last transaction that buyers are willing to buy at. The ask is the price closest to the last transaction that sellers are willing to sell at. You can also think of them as the market price of a stock--bid being the market price if you are selling at the market and ask being the price if you are buying at the market. The difference between the bid price and the ask price is called the spread.. It is a fee that the market maker pockets as payment for keeping the market liquid. Generally, you will only see bid and ask prices quoted for NASDAQ stocks. On the NY and American exchanges the spread is a more uniform 1/16 to 1/8 point.
