Imizekelo yeeasteroids

Ilizwi asteroid ithatha ukuba "inani lenkwenkwezi”. I-asteroid ngumzimba omncinci kuneplanethi kwaye mkhulu kune-meteorite. Ingaba ngamatye, icarbonaceous okanye isinyithi. Ii-Asteroids zijikeleza ilanga kwaye i-orbit yazo ingaphakathi kuleyo yeNeptune. Ngamanye amagama, bakwiNkqubo yeSola.

Uninzi lwee-asteroids zilele kumtya phakathi kweendlela zikaMars kunye neJupiter, ezaziwa njengebhanti yeasteroid. Nangona kunjalo, zikhona nezinye iiasteroids ezikufutshane neJupiter kunye nenani elikhulu eliwela ukujikeleza kwezinye iiplanethi.

Ubungakanani bee-asteroids buyahluka kakhulu. Eyona inkulu eyaziwayo ziikhilomitha ezili-1,000 ubude, ngelixa ezinye ii-asteroids ziziimitha ezilishumi ubude. ICeres yeyona asteroid inkulu.

Ubume bayo bungqukuva.

Ii-Asteroids azifane zibonwe ngeliso lenyama eMhlabeni. Nangona kunjalo, oku kunokwenzeka kwiimeko ze-asteroids kufutshane neplanethi yethu, ukongeza kwiVesta, i-asteroid engaphezulu kweekhilomitha ezingama-500, ebekwe kwelona bhanti.

I-Asteroids inokuhlelwa ngokweeparameter ezahlukeneyo:

Indawo: isikhundla sakho ngokumalunga nelanga kunye neeplanethi. Lo mgama ulinganiswa kwiiYunithi zeenkwenkwezi (AU). I-AU enye ilingana nomgama ophakathi komhlaba kunye nelanga.
Ukuqulunqwa: kugqitywa enkosi kukufunxwa kwembonakalo.
Ukubeka ngokwamaqela: zisekwe kumaxabiso: i-axis ebaluleke kakhulu, ubungqongqo kunye notyekelo lwe-orbit.

Ukufunda ngee asteroids kunye nezinye izinto zasezulwini kusetyenziswa umlinganiselo obizwa ngokuba yi "absolute magnitude", obubonakala bubukhulu obunokubakho kumgama ozii-parsecs ezilishumi kwindawo engenanto kwaphela. Lo mlinganiselo usetyenziswa kuba unxulumene ngokuthe ngqo nokukhanya kwezidalwa zasezulwini, nokuba umgama wazo ungakanani na emhlabeni. Ngesi sizathu, kwezinye iimeko idatha ethile malunga ne-asteroids (enje ngobubanzi) ayifumanekanga, kodwa ubukhulu bayo buhlala busaziwa.
