We investigated the cause of somewhat bimodal distribution of the Near-Earth Asteroids (NEAs) inclination. Numerical integrations, in term of Newtonian gravitation including thermal effect, were carried out on 270 artificial objects for 400 thousand years and on a thousand random-selected NEAs for one million years. Orbital coupling between distributions of semi major axis (a) and inclination (i) segregated at about 2 AU turns out to exhibit bump at about inclination of about 20°. This bump is emerged because of the diversity in orbital mobility of NEAs between regions of a 2 AU, in which correspond to the secular and the mean-motion resonances. NEAs which located at a > 2 AU are dominated by the asteroids whose i < 15° and are protected by the secular resonance (υ 6 ) of Saturn. In addition, thermal effect play a role in delivering NEAs through perihelia of the Terrestrial planets, mainly affect orbital diffusion of NEAs when passing through the υ 6 region, and somehow restrain NEAs from falling into the Sun.[/vc_column_text][vc_empty_space][vc_separator css=".vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}"][vc_empty_space][megatron_heading title="Author keywords" size="size-sm" text_align="text-left"][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=".vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}"][vc_empty_space][megatron_heading title="Indexed keywords" size="size-sm" text_align="text-left"][vc_column_text]Inclination,Near-earth asteroids,Thermal effect[/vc_column_text][vc_empty_space][vc_separator css=".vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}"][vc_empty_space][megatron_heading title="Funding details" size="size-sm" text_align="text-left"][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=".vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}"][vc_empty_space][megatron_heading title="DOI" size="size-sm" text_align="text-left"][vc_column_text]https://doi.org/10.1063/1.4917148[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
