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.
What is a 'Reverse Auction'. A reverse auction is a type of auction in which sellers bid for the prices at which they are willing to sell their goods and services. In a regular auction, a seller puts up an item and buyers place bids until the close of the auction, at which time the item goes to the highest bidder. In a reverse auction, the buyer puts up a request for a required good or service. Sellers then place bids for the amount they are willing to be paid for the good or service, and at the end of the auction the seller with the lowest amount wins.
