English: Diagrams showing the location and characteristics of the en:Juno clump of en:asteroids. Circles show asteroid sizes to scale (mean diameter), when present.

In the top diagrams, the en:proper orbital elements are plotted (en:inclination i_p vs. en:semi-major axis a_p on the left, and en:inclination i_p vs. eccentricity e_p on the right) for numbered en:asteroids in the en:main belt.

In the bottom enlargements, one has:

• core family members (shown in red) are those identified by the 1995 Zappala (V. Zappala et al, Icarus Vol. 116, p. 291 (1995)) HCM method analysis. The data set is here.
• additional significant family asteroids (shown in orange).
• additional significant non-family asteroids (shown in light blue).
• numbered asteroids in general (shown as small blue dots), from the AstDys database.

The location of asteroids that are very large and/or explicitly named on the plot is shown by a light cross within the circle.

Asteroid diameters were obtained from two sources:

• (thick circles): From the IRAS survey, when available (data set here).
• (thin circles): Otherwise, by assuming an albedo of 0.238 (value for en:3 Juno), and estimating from absolute magnitudes from the AstOrb database here.

The diagrams were created by me (Piotr Deuar) using proper element data for 96944 en:minor planets, which was obtained from the AstDys site. Data was dated March 2005, calculation was by Z. Knezevic and A. Milani.
