Believe it or not, but a crazy Australian fan "buys" Shah Rukh Khan a piece of the moon every year on his birthday.

"Yes, an Australian lady buys a little land on the moon for me every year on my birthday."

"She has been buying it for a while now and I get these certificates from the Lunar Republic Society," Shah Rukh Khan told a newspaper.

The Bollywood star who celebrated his 44th birthday Monday has apparently met his fan and she keeps in touch with him all year through mails.

"She writes me colourful emails (in the sense one line is red, one is blue and so on). I feel blessed to have the love of so many people worldwide."

According to one online lunar real estate agency, http://www.lunarregistry.com/, the Sea of Tranquility is the most sought-after address on the moon.

A 4,047 sq m plot of land (1 acre) costs US $37.50 (S$52.50). The actor currently "owns" several acres on the moon.

An "ownership package" includes a beautifully engraved parchment deed, a satellite photograph of the property and an information sheet detailing the geography of one's region.

An interactive Full Moon Atlas on CD-ROM is available at an additional cost.

People are allowed to buy up to 161, 874.2 sq m (40 acres) per transaction.

Proceeds from the purchase of the plots on the moon, go toward the Lunar Republic Society's programme for privatised human-based exploration, settlement and development of the Moon.

Now while there are many websites on the internet (based in the US, UK and Russia) that allows you to buy land on the moon, it doesn't mean you can charge NASA or other space agencies for trespassing when they land on your property.

Property ownership is permanently registered by the International Lunar Lands Registry in its annual publication, which is copyrighted and deposited in the United States Library of Congress.

It has international patent and trademark offices, including in the United Kingdom (UK Patent Office), Japan (Japan Copyright Office), Russia (Rospatent) and with the United Nations (UN Depository Library), in compliance with the Berne Convention.
