This planet is named in honor of Brown University, Providence, Rhode Island. ... Its astronomical history dates back to the transit of Venus in 1769, observed by Prof.Benjamin West. Two local streets are named Planet and Transit. The naming of the planet is also a tribute to the international reputation of Dr. Smiley.[5]
