When 1570 Brunonia was discovered on October 9, 1948 by Sylvain Julien Victor Arend at the Royal Observatory of Belgium in Uccle, Belgium, Arend wrote to Smiley:
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.<ref></ref>
