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 involves a buyer holding an auction for the purchase of a good or service and sellers biding on the price that they are willing to charge the buyer for it. The bidding is competitive, and all other things being equal, the lowest bidder will win the opportunity to sell to the buyer.
