Ka nui loa asteroids a me kā lākou mau ana. Asteroids poe lń

Asteroids a nīnūnē kŘhele, nui emi iki mahope o ke lākou Ana ia kino i loko o ka poe lń, e like Honua, Venusa, aʻo Mercury. Naʻe, ka mea hiki ole ke noonoo piha-fledged "kanaka" o ko mākou'āpana o ka Wiliau Hōkū.

ka papa kuhikuhiE kāʻei

Asteroids poe lń pulakaumaka i mau cii. Ka loa kilakila o ia i aia ma waena o nā orbits o Mars a me ka Dia. Kēia lālā o ka poe uuku wale no ua, ua kapaia ka papa kuhikuhiE asteroid kāʻei. Mass o nā mea i waiho 'aneʻi ma ka makahiki hookahi hae i negligible: ia mea wale 4% o ka Moon ka nuipa a. A he kuleana na makana i loko o keia kau hana i ka nui asteroids. A me kā lākou mau ana, a me ka neʻeʻana o ko lākou mau liʻiliʻi counterparts, e like me kiko'î e like me ka haku mele 'ana, palapala a me ka molekumu o, ua o Laielohelohe i ka noonoo ana o astronomers ma ke kakahiaka XIX kenekulia: Ceres, mua noʻonoʻo i ka nui asteroid, a me ka manawa attributable i ka helu o dwarf kŘhele, i weheia ka mea mua i loko o January 1801.

ma kela aoao o Neptune

Ke Kuiper kāʻei, Horta ao, a hoopuehu aku iwi kuamoʻo i ua noʻonoʻo a? Anoee like wahi, kahi i nui ka helu o ka poe liilii, ano lani kahi hope. Ka mua o kēia mau ua aia ma'ō aku o ka Astronomical o Neptune. Ua Ua wehe wale i ka 1992. Noiʻi manaʻo i ka Kuiper kāʻei mea nui aku, ua kīkoʻo akula, a oi nunui ma mua o ka like ho okumu ma waena o Mars a me ka Dia. Small kino ke aupuni '' aneʻi e okoa mai ka papa kuhikuhiE kāʻei mea haku mele: methane, ammonia a me ka wai i lanakila ma luna o ka hana pōhaku a me ka mea hiki ke hooheheeia, ano "kupa" kāʻei asteroids.

Ao kū i Horta i keia la ua ole ai, nae , keia kuhiakau ka pahuhopu nei me ka nui theories hōʻike no ka poe lń. Presumably ao Orta, i mea he spherical māhele'āina aia ma o aku o ka Astronomical o na hoku a ma ka loihi o ka pili ana i ka malamalama-makahiki , mai ka lā. Eia nā makahiki mea i haku o ka ammonia, methane a me ka wai hau.

Ka wahi o ka hele liʻiliʻi iwi kuamoʻo 'ano me kekahi mau Kuiper kāʻei. Epekema nō mai i kona kumu. Ua hoi kau mea oia hoi oʻano o ka hau.

Hoʻohālikelike comet asteroid

No ka pololei naauao o ke kumuhana mea e e nāu kekahi me nā Astronomical manaÿo: "Comet" a me ka "Asteroid". Elua la, aohe pono like i ka oko o kēia mau iauaeoia a hiki i 2006. Ma ka General Ahaolelo o IAU i ka la o makahiki o ka comet a me ka asteroid entrenched kekahi hiʻona, hiki oi a emi reliably wahi o kela ano lani kino i ka kekahi waeʻano.

Comet - he mea hele i ka loa elongated ka Astronomical. I ka hookokoke ana aku o ka la i ka hopena o ka sublimation o ka hau, kahi kokoke i kaʻili kai, ho okumu i ka comet a - he ao o ka lepo a me ka kinoea, a maoli he like me ka ka ho'ēmiʻana o ka mamao ma waena o ka makemake, a me ka luminary, a ua pinepine pu ma ke kahua o ka "huelo".

Asteroids coma e hana a nui i ka emi elongated ka Astronomical. A o ka poe e oni ana a trajectories i 'ano like me ka comets a manaoia ka ai-i kapaia o ka Korata: o ka mea ole comets (i mea ole a me ka mea ole comet i kapaʻia nā mea pau ka liu o nā mea a pau e yiaeaiiacaaeneiie waiwai a me ka hana i palapala ai kekahi).

Ka nui loa asteroids a me kā lākou mau ana

Maoli nui ma ka lewa loa o ka ukana i loko o ka papa kuhikuhiE asteroid kāʻei mea uuku loa. Ka hapa nui o ka nui o ke kino ke aupuni 'ma waena o Dia a me Mars, buke no ka eha o ka mea - ka mea, o Ceres, Vesta, Pallas a me ka gig. Mua i loko o ka makahiki 2006 ua noʻonoʻo i ka nui asteroid, a laila ka mea i haawiia mai i ke kūlana o ka dwarf Honua. Ceres - he kūpono kou hoʻopoepoe kino me ka anawaena o ma kahi o 1000 ei. Kona nuipa mea ma kahi o 32% o ka huina kaumaha o nā mea a pau iʻikeʻia nā paena kāʻei.

Ka loa papakaukau mea ma hope o Ceres o Vesta. Ma o ka nui o ka asteroid mamua o kona wale palladium (ma hope o ka hoʻomaopopo pono o Ceres, he dwarf Honua). Pallas ua ike okoa ia mai na mea e ae, a me ka unusually ikaika iho k'ki.

Gig - ka ha i ka nui a me ke kaumaha o ka mea Main kāʻei. I loko nō kona nui, ka mea, uaʻike mea ma hope mau puu uuku asteroids. O ke kumu ho i ka mea i ka gig - he loa pōwehiwehi mea.

A pau kēia mau kino revolve a puni ka Sun ma ka e like me mamua, e like me na hoku a, a me ka mai i kela kapa o ke alanui o ke noi ana o ka Honua.

hiʻona orbits

Ka nui loa asteroids a me kā lākou mau ka hele hoi ia paha i ka ia kānāwai, e like me ke koena o ka neʻeʻana kāʻei o ka 'ano like ke kino. Lākou mau orbits i mau, ua waiho olohelohe ia ma na hoku a, o ka oi aku o Dia ka lawe i ka nui keiki kanaka nunui.

By iki eccentric orbits ka ao ka a pau na asteroids. Honua asteroids kēia mau waiū Dia E ho'ākea i kekahi 'oni iki orbits. Mau offsets hiki ke ho'ākāka 'ia me he oscillation puni kekahi awelika kūlana. Ma kēlā me kēia mea oscillation asteroid ka hāhai mai i kekahi mau haneri o ka makahiki, no laila, na loina i ka lā i Aole lakou e lawa i ka möakäka hou a hōʻoia i kaʻimi naʻauao? Aiey iauaeoia. Nohona ma, nae, ke kuhiakau o ka loli orbits mea, he pono ole.

Ka hopena o ka pohupani hale orbits - mahuahua i ka manawa kūpono o ka hookui hookahe koko ana. I ka 2011, i ka 'ikepili paipai i Ceres, a Vesta i na maka i ka wā e hiki mai i i.

Ka nui loa asteroids a me kā lākou mau hana ma lalo o ka scrutiny o kānakaʻepekema mau. Waiwai hoʻololi i kā lākou orbits a me nāʻano a pau i hookaheia mālamalama ma luna o kekahi o ka makahiki kumu i loko o nā KālailaiʻIkepili kaʻina ua pinepine extrapolated a me ka mea nui ma mua o asteroids. asteroids ka hele ana këia a me ka hoʻohana 'ana i ka spacecraft, i ka manawa i ukali o kekahi mau mea. One March 6, 2015 Ua hookuu ia ma luna o ka Ceres ka Astronomical.
