Pengawa nyeliahka empas asteroid

Pengawa nyeliahka empas asteroid mungkur chara ke ulih dikena objek semak Bumi (NEO) ba kus ke bisi potensial belantak enggau Bumi ulih dialirka jauh, nagang penusah empas ke ngerusak.

Beberapa chara dikena nyeliahka empas asteroid udah dipejuraika.^[1] Bisi dua chara nyeliahka empas asteroid: ngubah trajektori utai nya ngambika enda belantak enggau Bumi, tauka ngubah utai nya enggau chara mechahka iya ngambika serpihan ti diasilka nya enda belantak enggau Bumi tauka saiz iya ti mit agi ngurangka penusah ti nyadi udah nya ngagai Bumi.^[2]

Empas kinetik

Empas kinetik ulih dijapai ngena utai ti besai, baka kapal angkasa tauka utai bukai ti semak Bumi ngambika belantak enggau asteroid, ngambika ulih ngelimpangka jalai asteroid. Chara ti baka tu udah tradisional bepelasarka meri empas ngagai pusat geometri asteroid. Dalam taun 2025, Lee Kin Thong merambu ngambika belantak eksentrik ungkup asteroid enggau paksi setengah besai mit dalam timpuh orbit sida enggau sukut intersepsyen ke besai agi maya empas ngembuan penguntung ke besai agi ngelimpangka asteroid nya jauh enggau penetap ke besai agi ari empas pusat geometri tradisional.^[3]

NASA ngelancarka kapal angkasa ti dikumbai "Uji Pengarah Asteroid Ganda" (DART) ti berat 610 kg kena 24 November 2021. Pengudah 10 bulan bejalai ba luar angkasa, DART belantak enggau asteroid "Dimorphos" ti dikumbai 26 September 2022. Penusah belantak nya dirikod ulih "LICIACube". Iya nunjukka orbit "Dimorphos" dipandakka 32 minit pengudah penusah empas nya nyadi.^[4]^[5]^[6]
