Chakavanzika cheTrojans nevaGiriki
Chakavanzika chehupenyu pamwe ndicho chikuru, asi kwete chega chakavanzika cheSistimu yedu iyo masayendisiti ari kurovera pfungwa dzavo. Kune vamwe, semuenzaniso, vaTrojans nevaGiriki, i.e. mapoka maviri ema<em>asteroid anotenderera Zuva mumikoto yakada kufanana neyokutenderera kweJupiter (4). Iwo akakomberedzwa akatenderedza mapoinzi ekusunungurwa (misoro yemakona matatu akaenzana ane hwaro huri chikamu cheZuva-Jupiter).
4 Trojans uye maGreek Orbiting Jupiter
Nei kune zvakawanda zveizvi zvinhu uye nei zvakarongwa nenzira yechienzi? Mukuwedzera, "munzira" yeJupiter kunewo asteroids e "musasa wechiGiriki", iyo inobata Jupiter mukufamba kwayo kwekufamba, ichifamba-famba panzvimbo yekusunungurwa L4, iri mu orbit 60 ° mberi kwepasi, uye ku "Trojan camp" tevera kuseri kwepasi, pedyo neL5, mune orbit 60 ° kuseri kweJupiter.
Zvekutaura nezvazvo Kuiper belt (5), kushanda kwayo, maererano nedzidziso dzechinyakare, hakusi nyorewo kududzira. Mukuwedzera, zvinhu zvakawanda zviri mariri zvinotenderera nenzira yechienzi, yakarerekera kusingawanzoitiki. Munguva pfupi yapfuura kwave nemafungiro ari kukura ekuti kusakanganiswa kunoonekwa munharaunda iyi kunokonzerwa nechinhu chikuru, iyo inonzi nyika yepfumbamwe, iyo, zvisinei, haina kuonekwa zvakananga. Masayendisiti ari kuyedza kubata neanomalies nenzira yavo - vari kuvaka mhando nyowani (6).
5 The Kuiper Belt Around The Solar System
Somuenzaniso, maererano nezvinodanwa Nicene modhi, iyo yakatanga kuratidzwa muna 2005, solar system yedu yaive idiki pakutanga, asi mazana mashoma emamiriyoni emakore mushure mekuumbwa kwayo. kutama kwepasi kuenderera mberi nekutenderera. Iyo Nice modhi inopa mhinduro inogoneka pakuumbwa kweUranus neNeptune, idzo dziri kure kutenderera kuti dziumbe kunyangwe mukutanga kwezuva nekuti density yenzvimbo yaive yakadzikira ipapo.
Sekureva kwaFrancesca DeMeo, nyanzvi yesainzi kuUS Harvard-Smithsonian Center yeAstrophysics (CfA), Jupiter yaive pedyo neZuva kare seMars ikozvino. Zvadaro, ichidzokera kunzira yayo yazvino, Jupiter yakaparadza rinenge bhandi rose reasteroid - chete 0,1% yehuwandu hweasteroid yakasara. Kune rimwe divi, kutama uku kwakatumirawo zvinhu zvidiki kubva kubhandi reasteroid kusvika kumucheto kwesolar system.
6. Mhando dzakasiyana-siyana dzekuumbwa kwemapuraneti masisitimu kubva kumaprotodisk enyaya.
Zvichida kutama kwehofori dzegasi mugadziriro yedu yezuva kwakakonzerawo kuti ma<em>asteroid nema<em>comet avongane nePasi, zvichipa pasi redu mvura. Izvi zvinogona kureva kuti mamiriro ekuumbwa kwemapuraneti ane zvinhu zvakaita sepasi pePasi haawanzo kuwanda, uye hupenyu hunogona kugara huripo pamwedzi ine chando kana makungwa makuru enyika. Iyi modhi inogona kutsanangura iyo inoshamisa nzvimbo yeTrojans nemaGreek, pamwe nehombe yeasteroid bombardment iyo nzvimbo yedu yepasirese yakaitika makore angangoita 3,9 bhiriyoni apfuura uye ayo maratidziro anooneka zvakajeka pamusoro peMwedzi. Zvakaitika paNyika ipapo Hadean era (kubva kuHadhesi, kana kuti Gehena rechiGiriki rekare).
