Description kāʻei asteroids o ka poe lń. Main kāʻei asteroids

Description o ka poe lń he ole wale 'ike e pili ana i ka ewalu kŘhele a me Pluto, akā, mau hale, a me ka helu nui o cosmic kino. O nā ka Kuiper kāʻei, ka hoʻopuehuʻia iwi kuamoʻo, i ka Oort ao, e like me ka asteroid kāʻei. Ka mea hope, e e kūkā mai ma lalo nei.

ka wehewehena

Kaʻia "asteroid" Ua hakuloli e William Herschel haku mele Charlza Berni. Ke olelo nei o Helene kumu, a 'o ia hoʻi "e like me ka hoku". Ke ano o ia i ka makahiki i ua pili i ka mea i ka hoʻopaʻa 'ana o hakahaka o ka makahiki ma telescope asteroids mea like i Star: nana aku la e like wahi like kŘhele a pau me nā huila.

Like me neia, aole mea i ho'ākāka 'ana o ka makahiki i kēia lā. I ka papa kuhikuhiE ano hiʻona o ka asteroid kāʻei mea, a like hale - nui. I ka lalo kali o - 50 m + anawaena uuku kino Space -. He meteor. Ka luna kali - ke anawaena o ka dwarf Honua Ceres, aneane 1000 ei.

Location a me kekahi mau hiʻona

Ke asteroid kāʻei ke moe ma waena o nā orbits o Mars a me ka Dia. I kēia manawa, ua oi aku 600.000 o kona mea, o ka mea ma luna o 400.000 i ko lakou mau helu, a hiki i ka inoa. Kahi o 98% o ka hope - mea asteroid kāʻei loihi, mai ka lā ma ke kaawale, o ka 2.2 hiki i 3,6 AU. Ua nui loa ke kino i waena o lākou - Ceres. Ma ka halawai o ka MAC i ka makahiki 2006,ʻo ia, a me Pluto a me kekahi mau 'ē aʻei kūpono i ke kūlana o ka dwarf Honua. ʻO kēia nui Vesta, Pallas, a Giga pu me Ceres hoolilo 51% o ka huina o ke kaupaonaʻana o ka asteroid kāʻei.

shape

Cosmic kino, aha i ke kāʻei, ma ka hou ana i na Ana i koe i ka helu o ke kī 'ano. i kahi pohaku mea, kuai i loko o kā lākou mau orbits a puni i ka lā a pau o ia mau mea. Loina o ka asteroids hoikeia mai ana, e like me ka rula, ka mea, i ole ma ka shape a me ka milo. Images ia ma ka spacecraft, e lele ma ka asteroid kāʻei i loko o mākou poe lń, ua hookupaa iho la ia mau mea nā mea mahuʻi. E like me ka noiʻi, i kēia palapala - i ka hopena o pinepine hookui hookahe koko ana asteroids i kekahi i kekahi, a me na mea.

'ole

I ka lā, ua hōʻike 'astronomers ekolu papa o asteroids e like me ka papa kuhikuhi' ona i loko o ko lākou haku mele:

• kalapona (Class C);
• silicate (papa S) me ka predominance o ka silikone;
• mea hiki ke hooheheeia (M kaha).

Ka mua mooolelo no ka hola 75% o nā asteroids ikeia. Kēia Mea Maluna, nae, kekahi haumana ka mea, i manaoia pono. I ko lakou manao, i ka naʻikepili mai i maopopo aku nei au i hehee ai predominates i loko o nā kino cosmic o ka asteroid kāʻei.

I ka makahiki 2010, he kime o astronomers i ka hana hoihoi loaʻa e pili ana i ka haku mele 'ana o asteroids. Ua loaʻa epekema ma ka ili o Themis lawa ka nui mea o keia ciia, wai hau. Ke huli i keʻae i kahiko o ka'āina i ke kuhiakau i kekahi o na kumu o ka wai ma luna o ka mea opiopio Honua, he asteroids.

nā Hiʻona

Ka mńmń holo 'awelika i i mea e ka Astronomical i ka lā i kēia wahi mea 20 km / mau. Ma keia hihia, kekahi kipi o ka papa kuhikuhiE asteroid kāʻei pana aku au i ekolu i eiwa Honua makahiki. No ka hapanui o ia wehewehe aku ma kekahi hōʻemi iki inclination o ka Astronomical a hiki i ka ecliptic pelane - 5-10º. Eia naʻe, he mau mea nona ka ala hana me ka honua pelane o kuapo puni ka malamalama nui kilakila huina o ka mai, e 70º. Kēia hiʻona lilo i ke kumu no ka Mea Maluna o asteroids i loko o nā subsystems: ka mea i lalo, a spherical. Ke inclination o orbits o nä mea o ke 'ano mua, ua emi ma mua a me ka ewaewa ole i ka 8º, i ka lua o ka - oi aku ma mua o ka mea i hoakaka ia waiwai.

muli

Ma ka umikumamaiwa kenekulia ka scientific kaiāulu i ua hoʻomano kamaʻilio nui kuhiakau e pili ana i ka mea i make Phaethon. Ka mamao mai Mars a hiki i Dia loa ai kilakila, a laila hiki kekahi, i ka Astronomical o kekahi Honua. Eia naʻe, ua manaʻo i keia la ua kuhi obsolete. Hoikehonua, astronomers hoopili aku kēia i ka wahi, kahi i ke kāʻei o asteroids, ka Honua ana pono i hiki ole. Ke kumu no keia ma Dia. Ke kinoea pilikua mea no loko o ka kakahiaka kuʻina o kona ho okumu i ka gravitational ia ma luna o ka wahi, e waiho kokoke ana i ka lā. He o Laielohelohe hapa o ka waiwai o keia ciia. 'Aʻole i lawe pio ai ma ka Dia kino i hoʻopuehuʻia i loko o kekahiʻaoʻao, protoasteroidov māhuahua wikiwiki, hoonuiia i ka helu o ka hookui hookahe koko ana. E like me ka hopena, aole lakou i kūkulu wale i ka nui a me ka leo, akā, e noho uuku. I ka holo ana o ia mau loli 'ka likelihood o kŘhele ma waena o Dia, a Mars lilo Aʻohe.

mau keiki

Dia a me kēia lā "aole e haalele wale" ka asteroid kāʻei. Kona ikaika umekaumaha ke kumu loli ma na orbits o kekahi o na kino. Ma lalo o kona aoao, he ka ai-kapa ole-e hele mau mea i loko o a aohe mea kokokeʻaʻohe asteroids. Kino leleʻaneʻi ma muli o ia i ka hookui ana me kekahi mea, ua pahu mai mai o ka ciia. I kekahi manawa, i kēia ka Astronomical ua hoʻololi ai i ka mea haʻalele i ka asteroid kāʻei.

hou apo

I ka papa kuhikuhiE asteroid kāʻei mea ole wale. Ma kona kae ua kau like i emi kilakila hoʻonaʻauao elua. I kekahi o kēia mau apo ua aia 'ana ma luna o ka Astronomical o Dia, a ua poe ma nā pūʻulu o nä mea:

• "Helene" mua kinoea kanaka nunui o ka hola 60º;
• "Trojans" ma hope o ka ua helu o nā degere.

A ano hiʻona o kēia mau kino i ke kumupaʻa o ko lākou neʻe. He hiki no i ka wahi o asteroids ma "Lagrange kumu", a i 'O ke kaulike ma nā mea a pau gravitational keiki ma luna o kēia mau mea.

I loko nō o ka kŘpa a pili koke ana i ka Honua, me ka asteroid kāʻei mea insufficiently hoʻopaʻa 'ana a me ka hoʻopaʻa nui na mea pohihihi. Ka mua o kēia, o ka papa, o ka kumu o na poe uuku wale no ka poe lń. Aia He He kamaʻilio ma keia manao, oiai ka mea, puhi hoomaopopo lawa, mākou i ole i loaa i ka maopopo e hooiaio ai.

Hoala nīnau a me kekahi mau hiʻona o ka 'ole o asteroids. Ua uaʻike, no ka laʻana, ua hiki kāʻei mea e pili pū ana i loko o kekahi kanaka e mahalo loa ai okoa mai kekahi i kekahi. I ka like o nā 'ano o nā asteroids a me kā lākou me Kinohi mea e pono nā no ka hoʻomaopopo i nā hanana mua i ke kahua o ka poe lń me ko kakou ike ana ia, a no ke kukulu ana i theories e pili ana i ka keʻano o ka hanaʻana' ia i loko o keʻena māhele o ka cosmos, i loko o nā nenoai o nā hoku.
