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.
A forward auction is the most common type of auction and it consists of one seller, and many potential buyers. This type of auction has been used for centuries, obviously way before the internet has been invented. A forward auction can either be B2B, B2C, or C2C. Four types of forward auctions are the English auction, the Yankee auction, the Dutch auction, and the Free-fall auction.
