Now that Oracle is actively decommissioning the site, it could, if it chose to do so, sell off the domain name and pocket a million or even more, experts estimate.

The Sun.com domain name could be worth between $1 and $2 million, estimated Jeff Kupietzky, CEO of Oversee.net, of much sought-after domain names.

"At just three letters it is short and memorable," he said, in an e-mail interview. "It is a positive word that has a high search volume."

"Sun.com is appealing because it could be used in a number of ways," said Paul Nicks, director of domain aftermarket services for the Go Daddy registrar. "Solar power companies, companies with 'sun' currently in their name, domain name investors or anyone looking to leverage the history behind the name could have a bidding interest."

Nicks estimated that, should the name be auctioned, it could fetch between $800,000 and $900,000.
