        lct_min -- Local civil time, minutes part.
        lct_sec -- Local civil time, seconds part.
        is_daylight_saving -- Is daylight savings in effect?
        zone_correction_hours -- Time zone correction, in hours.
        local_date_day -- Local date, day part.
        local_date_month -- Local date, month part.
        local_date_year -- Local date, year part.
        comet_name -- Name of comet, e.g., "Halley"

    Returns:
        comet_ra_hour -- Right ascension of comet (hour part)
        comet_ra_min -- Right ascension of comet (minutes part)
        comet_dec_deg -- Declination of comet (degrees part)
        comet_dec_min -- Declination of comet (minutes part)
        comet_dist_earth -- Comet's distance from Earth (AU)
