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 reverse auction (also called procurement auction, e-auction, sourcing event, e-sourcing) is a tool used in business-to-business procurement. In this process, the role of the buyer and seller is reversed, with the primary objective to compete purchase prices downwards. In an ordinary auction (also known as a forward auction), buyers compete to obtain a product or service. In a reverse auction, sellers compete to obtain business.
