719 Albert, provisional designation 1911 MT, is a stony asteroid, approximately 2.5 kilometers in diameter, classified as a near-Earth object of the Amor group of asteroids. It was discovered by Austrian astronomer Johann Palisa at the Vienna Observatory on 3 October 1911, and subsequently a lost minor planet for 89 years. The asteroid was named in memory of Albert Salomon Anselm von Rothschild, an Austrian philanthropist and banker. Albert was the second Amor asteroid discovered, the first being 433 Eros.
151 Abundantia is a stony main belt asteroid. It was discovered by Johann Palisa on 1 November 1875, from the Austrian Naval Observatory in Pula. The name was chosen by Edmund Weiss of the Vienna Observatory; although the name refers to Abundantia, a Roman goddess of luck, it was also chosen to celebrate the increasing numbers of asteroids that were being discovered in the 1870s.
220 Stephania is a dark background asteroid from the inner regions of the asteroid belt, approximately 32 km (20 mi) in diameter. It was discovered on 19 May 1881, by Austrian astronomer Johann Palisa at the Vienna Observatory. The C-type asteroid has a rotation period of 18.2 hours. It was named after Princess Stéphanie of Belgium.
225 Henrietta is a very large outer main-belt asteroid. It was discovered by Austrian astronomer Johann Palisa on April 19, 1882, in Vienna and named after Henrietta, wife of astronomer Pierre J. C. Janssen. The asteroid is orbiting at a distance of 3.39 AU from the Sun with a period of 6.24 years and an eccentricity (ovalness) of 0.26. The orbital plane is inclined at an angle of 20.9° to the plane of the ecliptic. 225 Henrietta belongs to Cybele group of asteroids and is probably in a 4:7 orbital resonance with the planet Jupiter.
228 Agathe is a stony main belt asteroid, about 9 kilometers in diameter. It was discovered by Johann Palisa on 19 August 1882 at Vienna Observatory, Austria. Photometric observations during 2003 showed a rotation period of 6.48 ± 0.01 hours with a brightness variation of 0.27 ± 0.03 in magnitude. An earlier study yielded results that are consistent with these estimates. Agathe is the lowest numbered asteroid to have an Earth-MOID as low as 0.657 AU (98.3 million km). On 23 August 2029 the asteroid will be 0.659 AU (98.6 million km) from Earth.
254 Augusta is a main-belt asteroid, discovered on 31 March 1886 by astronomer Johann Palisa at Vienna Observatory, Austria. The stony S-type asteroid measures about 12 kilometers in diameter. It is the first-numbered member of the Augusta family, after which the small Asteroid family and subgroup of the main-belt has been named. Augusta was named after the German–Austrian writer Auguste von Littrow (1819–1890), widow of astronomer Carl Ludwig von Littrow, who was a former director of the Vienna Observatory.
257 Silesia is a large Main belt asteroid, about 73 kilometers in diameter. It was discovered by Johann Palisa on 5 April 1886 at Vienna Observatory, Austria.
290 Bruna is a main belt asteroid that was discovered on 20 March 1890 by Johann Palisa, an Austrian astronomer at the Vienna Observatory.
321 Florentina is an S-type (stony) main belt asteroid with a diameter of 28 km. It was discovered by Johann Palisa on 15 October 1891 in Vienna. He named the asteroid for his daughter, Florentine. Between 1874 and 1923, Palisa discovered a total of 122 asteroids.
716 Berkeley is a background asteroid from the central regions of the asteroid belt. It was discovered by Austrian astronomer Johann Palisa at the Vienna Observatory on 30 July 1911. The stony S-type asteroid has a rotation period of 15.6 hours and measures approximately 21 kilometers in diameter. It was named after the city of Berkeley, California, where the discoverer's colleague Armin Otto Leuschner (1868–1953) was the director of the local observatory.
718 Erida is a minor planet orbiting the Sun. It was discovered at Vienna on September 29, 1911, by Austrian astronomer Johann Palisa, and was named for Erida Leuschner, daughter of astronomer Armin Otto Leuschner. It is orbiting at a distance of 3.06 AU with a period of 5.34 yr and an eccentricity of 0.20. The orbital plane of this asteroid is inclined by an angle of 6.9° to the plane of the ecliptic.
722 Frieda is a bright background asteroid and slow rotator from the inner regions of the asteroid belt. It was discovered by Austrian astronomer Johann Palisa at the Vienna Observatory on 18 October 1911. The stony S-type asteroid has a notably long rotation period of 131.1 hours and measures approximately 9 kilometers in diameter. It was named after Frieda Hillebrand, daughter of Austrian astronomer Karl Hillebrand (1861–1939), and grand-daughter of Edmund Weiss (1837–1917) who had been the director of the discovering observatory.
724 Hapag is a minor planet orbiting the Sun in the asteroid belt that was found by Austrian astronomer Johann Palisa in 1911 and named after the German shipping company Hamburg America Line. It was assigned a provisional name of 1911 NC, then became a lost asteroid until it was rediscovered in 1988 as 1988 VG2 by Tsutomu Hioki and N. Kawasato at Okutama, Japan.
730 Athanasia is a background asteroid from the inner regions of the asteroid belt, approximately 4.5 kilometers in diameter. It was discovered by Austrian astronomer Johann Palisa at the Vienna Observatory on 10 April 1912. The presumed stony S-type asteroid has a rotation period of 5.7 hours and is likely very elongated in shape. It was named Athanasia, the Greek word for "immortality".
794 Irenaea is a dark background asteroid from the outer regions of the asteroid belt. It was discovered on 27 August 1914, by Austrian astronomer Johann Palisa at the Vienna Observatory. The presumed C-type asteroid has a rotation period of 9.1 hours and measures approximately 36 kilometers in diameter. It was likely named after Irene Hillebrand, daughter of Austrian astronomer Edmund Weiss (1837–1917).
827 Wolfiana, provisional designation 1916 ZW, is a Florian asteroid from the inner regions of the asteroid belt, approximately 8 kilometers in diameter. It was discovered at Vienna Observatory on 29 August 1916, by Austrian astronomer Johann Palisa, who named it after German astronomer Max Wolf. The assumed stony asteroid has a rotation period of 4.0654 hours.
941 Murray is a background asteroid, approximately 18 kilometers in diameter, located in the central region of the asteroid belt. It was discovered by Austrian astronomer Johann Palisa at the Vienna Observatory on 10 October 1920. The X-type asteroid has a short rotation period of 3.4 hours. It was named after British professor Gilbert Murray (1866–1957).
964 Subamara, is a stony background asteroid from the outer regions of the asteroid belt, approximately 20 kilometers in diameter. It was discovered by Austrian astronomer Johann Palisa at the Vienna Observatory on 27 October 1921. The S-type asteroid has a rotation period of 6.9 hours. It was named for the observatory's "very bitter" observing conditions due to light pollution.
1073 Gellivara, provisional designation 1923 OW, is a dark Themistian asteroid, approximately 27 kilometers in diameter, located in the outer regions of the asteroid belt. It was discovered by Austrian astronomer Johann Palisa at the Vienna Observatory on 14 September 1923, and later named after the Swedish town of Gällivare.
1235 Schorria, is a Hungaria asteroid, sizable Mars-crosser, and exceptionally slow rotator from the inner region of the asteroid belt. The carbonaceous C-type asteroid has an outstandingly long rotation period of 1265 hours and measures approximately 5.5 kilometers kilometers in diameter. It was discovered by Karl Reinmuth at Heidelberg Observatory in southwest Germany on 18 October 1931, and named after German astronomer Richard Schorr (1867–1951).
