Observation of asteroids is crucial for acquiring their lightcurve data, which can be used to refine asteroid models, reconstruct theirshapes, and derive more astrophysical parameters. This study proposes a novel computational method to determine the suitable
observation windows for asteroid (101955) Bennu from 2024 to 2044, aiming to supplement its missing lightcurve data. By analyzing the variations of phase angle (α), elongation (e), and PABS latitude (Θ), the optimal observation and closest approachdates are identified. The results show that the most suitable observation windows for (101955) Bennu are from 2024-05-12 to 2024-06-22, from 2030-05-14 to 2030-07-03, from 2036-05-26 to 2036-07-12, from 2042-06-10 to 2042-07-24, and from 2043-02-28 to 2043-03-15 during which the missing PABS latitude (Θ) intervals can be filled. The proposed method provides valuable guidance for planning asteroid observations, enabling more accurate shape inversion and enhanced predictions of Earth-impact probabilities,ultimately strengthening the ability to prevent and mitigate potential asteroid impact hazards
