695 Bella is a minor planet orbiting the Sun.
Although this asteroid has dynamic properties that make it a candidate for the Maria family, the spectral properties of the object indicate it is most likely an interloper. Instead, it may have been spalled off from 6 Hebe or its parent body. 695 Bella and 6 Hebe orbit on opposite sides of the 3:1 Kirkwood gap, and the two have similar orbital elements. [2]
Hebe is a large main-belt asteroid, containing around 0.5% of the mass of the belt. However, due to its apparently high bulk density, Hebe does not rank among the top twenty asteroids by volume. This high bulk density suggests an extremely solid body that has not been impacted by collisions, which is not typical of asteroids of its size – they tend to be loosely-bound rubble piles.
Lameia is a typical main belt asteroid. It was discovered by Austrian astronomer Johann Palisa on 5 June 1885 in Vienna and was named after the Lamia, a lover of Zeus in Ancient Greek mythology. 248 Lameia is orbiting the Sun with a period of 3.88 years and a low eccentricity (ovalness) of 0.067. The semimajor axis of 2.47 AU is slightly inward from the 3:1 Kirkwood Gap. Its orbital plane is inclined by 4° to the plane of the ecliptic.
Ornamenta is a relatively large main-belt asteroid, measuring 118 km in diameter. It is classified as a C-type asteroid and is probably composed of carbonaceous material.
Ottilia is a large main-belt asteroid. It was discovered by Max Wolf on March 16, 1895, in Heidelberg. It is named after the Germanic folkloric character Ottilia.
Hungaria is a relatively small asteroid orbiting in the inner asteroid belt. It is an E-type (high-albedo) asteroid. It is the namesake of the Hungaria asteroids, which orbit the Sun on the inside of the 1:4 Kirkwood gap, standing out of the core of the asteroid belt.
1578 Kirkwood, provisional designation 1951 AT, is a Hilda asteroid from the outermost regions of the asteroid belt, approximately 52 kilometers in diameter. It was discovered on 10 January 1951, by astronomers of the Indiana Asteroid Program at Goethe Link Observatory in Indiana, United States. The asteroid was named after American astronomer Daniel Kirkwood.
945 Barcelona is a minor planet orbiting the Sun in the Asteroid belt. It was discovered 3 February 1921 from Barcelona by the Catalan astronomer Josep Comas i Solà (1868–1937) and named for the city of Barcelona (Spain), the birthplace of the discoverer. It has an estimated diameter of 25.5 km.
616 Elly is a minor planet orbiting the Sun. It is a member of the Maria family of asteroids.
677 Aaltje is a main-belt minor planet orbiting the Sun, discovered by August Kopff at Heidelberg on January 18, 1909. It was named after the Dutch singer Aaltje Noordewier-Reddingius.
686 Gersuind is a minor planet orbiting the Sun that was discovered by German astronomer August Kopff on 15 August 1909 from Heidelberg. It was named after a character in Gerhart Hauptmann's play Gersuind.
714 Ulula is a main belt asteroid. It is orbiting the Sun near the 3:1 Kirkwood Gap with a period of 4.04 years and an eccentricity of 0.057. It was discovered by German astronomer J. Helffrich on 18 May 1911 from the Heidelberg Observatory and was named after an order of owls. The asteroid has a mean radius of 20 km and is spinning with a rotation period of seven hours. Its pole of rotation lies just 4–14° away from the plane of the ecliptic. The surface spectrum shows a pyroxene chemistry and is consistent with mesosiderites/HED meteorites.
729 Watsonia is a rare-type asteroid and namesake of the Watsonia family from the central region of the asteroid belt. It was named after the Canadian-American astronomer James C. Watson. Watsonia occulted the star 54 Leonis on 2013 Mar 03 at 01:48.
780 Armenia is a minor planet in the asteroid belt orbiting the Sun. It is named after the Kingdom of Armenia, now Armenia. This object is orbiting at a distance of 3.11 AU with an eccentricity of 0.097 and a period of 5.50 yr. The orbital plane is inclined at an angle of 19.1° to the plane of rotation. This asteroid spans a girth of ~94 km. The long rotation period of this asteroid necessitated light curve data from more than one latitude. The overlapping data provided a solution with a period of 19.891±0.002 h and a brightness amplitude of 0.18±0.03 in magnitude.
781 Kartvelia is a minor planet orbiting the Sun that was discovered by Russian astronomer Grigory Neujmin on January 25, 1914. Kartvelia comes from the historic name for the inhabitants of the nation of Georgia. This object is orbiting at a distance of 3.22 AU with an eccentricity (ovalness) of 0.12 and a period of 5.78 yr. The orbital plane is inclined at an angle of 19.1° to the plane of the ecliptic.
787 Moskva is a minor planet orbiting the Sun. It is a dynamic member of the Maria asteroid family orbiting near the 3:1 Kirkwood gap. This is an S-type (stony) asteroid spanning 27 km. The surface mineralogy is consistent with mesosiderite silicates.
875 Nymphe is a minor planet orbiting the Sun. It is a member of the Maria family of asteroids.
879 Ricarda is a minor planet orbiting the Sun that was discovered by German astronomer Max Wolf on July 22, 1917.
897 Lysistrata is a minor planet orbiting the Sun that was discovered by German astronomer Max Wolf on August 3, 1918.
975 Perseverantia is a minor planet orbiting the Sun that was discovered by Austrian astronomer Johann Palisa on 27 March 1922.
The Maria family is a collisional asteroid family located in the inner parts of the intermediate asteroid belt, near the 1:3 Kirkwood gap. The family consist of several thousand stony S-type asteroids. It is named after its parent body and lowest numbered member, the asteroid 170 Maria. It is also known as the Roma family, named after its alternative parent body, 472 Roma.
