(CBS News) Saturday's Powerball win could make you as rich as Elton John.

The current jackpot is a staggering $320 million, the net worth of Britain's biggest star.

It will be the sixth-largest ever draw in Powerball history, but could grow even larger as people hear of the amount at stake, and rush to buy a ticket in the next 24 hours.

No one has won the Powerball jackpot since early February, when Dave Honeywell in Virginia bought the winning ticket for the $217 million jackpot.

The largest Powerball jackpot ever came in at $587.5 million in November. The winning numbers were picked on two different tickets - one by a couple in Missouri and the other by an Arizona man - and the jackpot was split.

Nebraska still holds the record for the largest Powerball jackpot won on a single ticket - $365 million. That jackpot was won by eight workers at a Lincoln, Neb., meatpacking plant in February 2006.

The odds of winning Saturday's Powerball are 1 in 175 million ... that's just over half of the jackpot.
