Want to have lunch with Apple CEO Tim Cook at the company's new "spaceship" Apple Park headquarters in Cupertino, California? It won't come cheap.

In partnership with online auction site Charitybuzz, Cook is auctioning off a lunch with him at Apple's 175-acre campus that has yet to be finished. The proceeds will go to the Robert F Kennedy Human Rights organisation. The estimated value of the exclusive lunch is a whopping $100,000 (£77,477).

Interested bidders will have until 16 May to bid on the exclusive lunch. The highest bidder will be able to bring a guest to share the experience that will last around one hour. The cost of the meal is included.

There have been nine bids on the lunch so far with the highest one at $84,888 at the time of writing. A similar auction for a coffee with Cook in 2013 sold for $610,000.

The winning bidder will get the unique opportunity to chat and dine with the powerful executive of one of the most valuable and innovative companies in the world.

"Tim was recently honoured with the Newseum's Free Speech award for creating technology that changed the way people communicate and for using his position to take a public stand on issues like racial equality, privacy, the environment and LGBT rights," Charitybuzz's website reads.

"He has also been named Person of the Year by the Financial Times and he was ranked #1 on Fortune magazine's 2015 list of the World's Greatest Leaders. Apple has ranked #1 on Fortune's World's Most Admired Companies for the past ten years, including each year Tim has been CEO."

The lucky winner will also get to check out Apple's brand new, futuristic headquarters that was conceived of by late co-founder and CEO Steve Jobs.

The campus, which has been in development since 2014, runs on 100% renewable energy and one of the largest on-site solar energy installations in the world. It includes a 100,000 sq ft fitness centre for Apple employees, secure R&D facilities, the Steve Jobs Theatre, two miles of walking and running paths for employees, a meadow, orchard and pond.

There will be a visitors centre open to the public as well that includes an Apple Store and a cafe. Recent drone footage showed the campus is in the final stages of construction.

More than 12,000 employees are moving into the ring-shaped building over six months.
