78 Diana

78 Diana (dye-an'-a) is a large and dark main-belt asteroid. Its composition is carbonaceous and primitive. It was discovered by Robert Luther on March 15, 1863, and named after Diana, Roman goddess of the hunt. 78 Diana occulted a star on September 4, 1980. A diameter of 116 km was measured, closely matching the value given by the IRAS satellite.

Photometric observations of this asteroid during 1986 and 2006–08 gave a light curve with a period of 7.2991 hours and a brightness variation in the range 0.02–0.104 magnitude. Based upon radar data, the near surface solid density of the asteroid is 2.7+0.8
−0.5 g cm⁻³.

Diana is expected to pass about 0.003 AU (450,000 km; 280,000 mi) from (29075) 1950 DA on August 5, 2150. Main-belt asteroid 4217 Engelhardt (~9 km in diameter) will pass about 0.0017 AU (250,000 km; 160,000 mi) from (29075) 1950 DA in 2736.

Diana (Saint-Gaudens)

Diana – also known as Diana of the Tower – is an iconic statue by sculptor Augustus Saint-Gaudens. Once a famous New York City landmark, the second version stood atop the tower of Madison Square Garden from 1893 to 1925. Since 1932, it has been in the collection of the Philadelphia Museum of Art.

First Version (1891-1892)

"Diana" was commissioned by architect Stanford White as a weathervane for the tower of Madison Square Garden, a theater-and-dining complex at 26th Street and Madison Avenue in Manhattan. He talked his friend Saint-Gaudens into creating it at no charge, and picked up the cost of materials. Model Julia "Dudie" Baird posed for the body of the statue. Its face is that of Davida Johnson Clark, Saint-Gauden's long-time model and mother of his illegitimate son Louis.

The first version – built by the W. H. Mullins Manufacturing Company in Salem, Ohio – was 18 ft (5.5 m) tall and weighed 1,800 lb (820 kg). Saint-Gaudens's design specified that the figure appear to delicately balance on its left toe atop a ball. However, the Ohio metal shop was unable to pass the rotating rod through the toe, so the design was altered and the figure instead was poised (less-gracefully) on its heel.
