Alex Boese has a great article on About Entertainment on the history of people who claimed ownership of stars, moons, and planets and then sold deeds to plots of land on the heavenly bodies. And they had buyers!
In 2013, Maria Angeles Duran began selling plots of land on eBay. That, in itself, isn't unusual, but the land she was selling was located on the sun. She offered square-meter plots for the price of 1 euro each. By 2015, she had over 600 buyers, but then eBay pulled the plug on her, saying her auctions violated its "intangible goods" policy.
Duran didn't take this lying down. She sued the auction site for violation of contract, arguing that the sun is, indeed, a tangible object, and a Spanish court agreed to hear her case.
