The bond albedo of borrelly is 0. 009 ± 0. 002, the lowest of any object in the solar system. The physical photometric parameters of the comet are similar to asteroids, but the optically active portion of its … At encounter the near-nucleus coma was dominated by a prominent dust jet that resolved into at least 3 smaller jets emanating from a broad basin in the middle of the nucleus.
Images from the ds1 micas ccd camera reveal in three dimensions, the complex characteristics of borrelly's nucleus, coma, and jets. Observations with the hubble space telescope (hst) during the previous apparition of borrelly yielded an estimated rotation period of 25 0. 5 h, nucleus size of 4. 4 0. 3 by 1. 8 We present imaging and spectroscopic data on comet 19p/ borrelly that were obtained around the time of the deep space 1 encounter and in subsequent months. In the four months after per-ihelion, the … In support of the nasa deep space 1 (ds1) mission to comet 19p/borrelly, we obtained hubble space telescope (hst) images and ultraviolet (uv) spectra of the comet near the time of the ds1 flyby in … The nucleus, coma, and dust jets of short-period comet 19p/borrelly were imaged from the deep space 1 spacecraft during its close flyby in september 2001. A prominent jet dominated the near-nucleus …
