This will line_3: give the first true image of this outermost planet line_4: in the solar system, the only one of the outer planets that line_5: has not been visited by the Voyager probes. Pluto will line_6: subtend approximately 20 pixels across, while Charon, line_7: separated from Pluto by about 70 pixels, will be only 10 line_8: pixels across. The image will add important constraints line_9: to ground-based eclipse mapping reconstructions, and greatly line_10: improve our knowledge of the orbital elements of this line_11: intriguing system ! ! end of abstract general_form_proposers: lname: MACCHETTO fname: F. inst: CALTECH country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: For FOC pretties program. ! !end of general form text general_form_address: lname: MACCHETTO fname: DUCCIO title: DR category: PI ! lname: MACCHETTO fname: F.
