Stamp for Pluto's discoverer

Here is a campaign to promote a stamp for the discoverer of Pluto. Clyde Tombaugh died 10 years ago on January 17 so he eligible to be on a stamp.

Baxter started a Web site,www.clydetombaugh.com, in January 2006 to collect online signatures for his petition asking the Citizens' Stamp Advisory Committee to approve a stamp honoring Tombaugh. U.S. Postal Service policy states a person must be dead at least 10 years before being honored on a postage stamp -- making Tombaugh eligible as of Jan. 17.

"I don't know what kind of impact the petition will have, but I figured it couldn't hurt," Baxter said.

Baxter said he has collected about 2,000 signatures so far, and hopes to get a lot more before submitting the petition to the CSAC later this year. Among the petition signers is Michael Brown of the California Institute of Technology, who in January 2005 discovered Eris, a dwarf planet that measures about 70 miles wider than Pluto and is the farthest known object in the solar system.
