Image Details
Caption: Figure 5.
(Upper:) Composite of 21 uncontaminated Hubble images of Bennu (total exposure 6090 s) at rH = 0.924 au on UT 2023 September 24/25. No significant radial structures are evident. (Lower:) Same but for a composite image of 133P/Elst–Pizarro at rH = 2.725 au on UT 2013 July 10 having 3984 s total integration (from D. Jewitt et al. 2014) with azimuthal plot on the right. The dotted circles in the left-hand panels for both objects have radius 100 pixels = 4﹩\mathop{.}\limits^{^{\prime\prime} }﹩0. A vertical red line marks the projected negative heliocentric velocity vector. Vertical black lines show significant radial image artifacts.
