Hermes, the Messenger of Gods & Asteroid No. 69230 Hermes - Tulln an der Donau, Austria - Extraterrestrial Locations on Waymarking.com

The new fountain installed at the end of shopping street Wienerstarsse in Tulln an der Donau in 1994 during the street reconstruction is called Hermes fountain (Hermesbrunnen). On its top a darkened brass statue of the Greek God Hormes is installed. It is the work of Hungarian artist Márkus Péter and the statue almost the copy of the statue installed on one of Budapest fountains.

69230 Asteroid

69230 Hermes is an Apollo, Mars- and Venus-crosser binary asteroid that passed Earth at about twice the distance of the Moon on October 30, 1937. It is named after the Greek god Hermes. At the time, this was the closest known approach of an asteroid to the Earth. Not until 1989 was a closer approach (by 4581 Asclepius) observed. At closest approach, Hermes was moving 5° per hour across the sky and reached 8th magnitude.

It was discovered by Karl Reinmuth in images taken at Heidelberg Observatory on October 28, 1937. Only four days of observations could be made before Hermes became too faint to be seen in the telescopes of the day. This was not enough to calculate an orbit, and Hermes was "lost". It thus did not receive a number, but Reinmuth nevertheless named it after the Greek god Hermes. It was the only unnumbered but named asteroid, having only the provisional designation 1937 UB.

On October 15, 2003, Brian A. Skiff of the LONEOS project made an asteroid observation that, when the orbit was calculated backwards in time (by Timothy B. Spahr, Steven Chesley and Paul Chodas), turned out to be a rediscovery of Hermes. The orbit is now well known, and Hermes has been assigned sequential number 69230. In retrospect it turned out that Hermes came even closer to the Earth in 1942 than in 1937, within 1.7 Moon distances, without being observed. On October 30, 1937, it passed 0.00494 AU (739,000 km; 459,000 mi) from the Earth and on April 26, 1942, it passed 0.0042415 AU (634,520 km; 394,270 mi) from Earth.

Radar observations led by Jean-Luc Margot at Arecibo Observatory and Goldstone in October and November 2003 showed Hermes to be a binary asteroid. The primary and secondary components have nearly identical radii of 300–450 m (980–1,480 ft), and their orbital separation is only 1,200 metres.
