He aha mea he meteor? Meteora: Hawaii photo. Asteroids, comets, meteors, meteorites

Asteroids, comets, meteors, meteorites - Astronomical mea i ikeia e ia i ka ia no ka mea uninitiated i loko o nā kumu o ka 'epekema a ano lani kahi. I mea e oko i loko o kekahi mau aoao. Ka waiwai i emi iho asteroids, comets, meteors, meteorites, e hoomanao e lawa. Lakou kekahi i kekahi mea like: like mea i ke koko, e like me na poe uuku wale, pinepine hoʻolaha me ka lewa'ōpala. Ia mea he meteor, pehea ia i kekahi, mai ka asteroid a comet, aha nō kā lākou waiwai a me ka molekumu o, a ana au i ke ma lalo nei.

waʻa, aea

Comets - makahiki mea, oia no ka paʻahau kinoea, a me ka pohaku. Ka mea, originate i loko o ke kaawale ana wahi o ka poe lń. Hoikehonua, haumana i? Aaeaaaaony i ka papa kuhikuhiE kumu o comets - Ua interconnected Kuiper kāʻei, a me ka hele liilii iwi kuamoʻo, a hypothetically na Oort ao.

Comets i loa elongated orbits. Ma ke kokoke i ka Sun, ka mea hana i ka coma a me ka huelo. Mau kumu he poe e yiaeaiiacaaeneiie gaseous waiwai (ka wai uahi, ammonia, methane), ka lepo a me na pohaku. Ke poo o ka comet a coma, - i ka iwi o ka minuke (particles), ai olinolino a me kaʻike pono. Ua loaʻa he spherical shape a hiki kona i kā mākou nui ma ka wanaao i ka lā ma luna o ka mamao o 1.5-2 Astronomical Unit.

Ma mua o ka coma o ka comet nucleus ka moana. He IeAUPIIe, IAa IO eiaao He kŘpa a uuku ka nui a me ka elongated shape. Ma ka nui loa mai o ka 'ōlelo o ka la - i ka mea a pau i koe o ka comet. Ua ninoieo o ka paʻahau kinoea a me nā pōhaku.

'ano o nā comets

Na Mea Maluna o kēia mau ano lani kahi i kā lākou alapine (frequency) o ke lapaau a puni ka honua. Comets e lele a puni o ka Sun ma ka emi o ka 200 o kona mau makahiki, ua kapaia pōkole-manawa. Loa pinepine, ka mea, hāʻule i loko o ka pā wahi o ko mākou planetary'ōnaehana, mai ka Kuiper kāʻei a hoopuehu aku iwi kuamoʻo. Loa-au comets e haliu ae la ia a hiki i ka manawa i oi aku mamua o 200 makahiki. Ko lakou "'āina" - ka Oort ao.

"Small Ka"

Asteroids komo o ka hardwood. I nui ka mea, he mau loa wahi emi mahope kŘhele, eia nae lala kekahi o kēia mau makahiki he mea i ukali. Ka hapa nui o ka nīnūnē kŘhele, ka mea i kapaia e like me mamua, i kia ma ka papa kuhikuhiE asteroid kāʻei, Aia ma waena o nā orbits o Mars a me ka Dia.

I ka huina helu o ia ano lani kahi, i ikeia no ka 2015 loa 670.000. I loko nō ia he kilakila helu, i ka makana o ka asteroids i loko o ka hū o nā mea i loko o ka poe lń mea negligible - wale 3-3.6 m 10 ²¹ kg. He wale 4% o ka like aiao o ka Moon.

E nā asteroids, i nā mea a pau uuku kino. Ke ana no ka koho o ke anawaena. Inā ia aku i 30 m, o ka mea ua manaoia e ia i asteroid. Kino me ka liʻiliʻi Ana i kapaia meteoroids.

Mea Maluna o asteroids

Ke kumu o ka Hoʻohui 'ia o kēia mau ano lani kahi mea he mau mea kiko'î. Asteroids hui hiʻona o ko lākou mau orbits a me ka pae o ka hiki malamalama i ka lewa, mai ko lakou mau surfaces.

E like me ka lua o ana i ka papa kuhikuhiE papa ekolu:

• kalapona (C);
• silicate (S);
• mea hiki ke hooheheeia (M).

Ka waeʻano mua mai nā 'o ka hola 75% o nā mea a pau i keia la ikeia asteroids. Me ka hou o ka ipu, a B piha study o ia mau mea Mea Maluna Hoʻonui i ka pono.

meteoroids

Meteoroid - kekahi 'ano o ka cosmic kino. Kēia mea,ʻaʻole i nā asteroids, comets, meteors paha meteorites. Ke peculiarity o kēia mau mea - uuku nui. Meteoroids ma na Ana i kau ma waena o nā asteroids a me ka makahiki i ka lepo. Penei, ka mea e lawe aku i ke kino me ke anawaena o ka emi o 30 m. Ua hoʻoholo kekahi kānakaʻepekema i ka meteoroid like me kaʻoʻoleʻa kino me ke anawaena o ka 100 m + i 10 m. E like me kā lākou mau kumu, ka mea e iniiaiie paha kiʻekiʻe, i ua hanaʻia ma hope o ka make ana o ka nui mea.

I ko lakou komo ana i ka honua i ka lewa meteoroid glows. A maanei mākou e, ua kokoke i ka pane ana i ka ninau, aha mea he meteor.

pana hoku

I kekahi manawa, i ka amo ana no hoku ma ka lani po kekahi koke akula nô ia, wehewehe he uuku piʻo a me ka nalo. ʻO wai ka mea i loa ike i ka me, ua ike no oia i ke meteor. Kēia "pana hoku" i i ole pili i ka maoli hoku. Meteor -ʻaneʻane ka lewa kŰia i ia lŘlŘ ka wā ea i loko o ka iwi o ko mākou Honua uuku pepa paia mea (mau meteoroids). Ka malama'ālohilohi o ka waihonaʻike hilinaʻi nui ma luna o ka palapala cosmic kino nui. Inā he meteor alohi oi ma mua o ka lima o ka nui, ka mea, ua kapaʻia he fireball.

e kiai ana ia

Mauʻike manaʻo hiki ke mahalo wale mai ka Honua ma ka mea i ka lewa. Meteors ma ka Moon paha Mercury hiki ole ke malama, no ka mea, nele ea eke.

Inā "haule hoku" kupono rula e ike hiki kela po. E aho nō eʻai i nā meteors i ka manawa kupono, a ma ka loihi, mai ka nui a me ka emi ikaika kumu oʻimi hoʻopunipuni malamalama. ¶ A i loko o ka lani, e ia i ka mahina. Ma keia hihia, ka mea hiki ke ike i ka maka kapa ole ma lalo o 5 no hora. Mea, e alakai ana i ke ano o ka mea hookahi "My Stars" e revolve a puni i ka lā i loko o ka likeʻole ma o orbits. No laila, hiki ole ke wānana pololei i ka wahi a me ka manawa o ko lākou mau helehelena i loko o ka lani.

muliwai

Meteora, kiʻi o ka a i kekahi hōʻike i loko o ka pauku, e like me ka rula, i he mau mea kaʻu okoa kumu. Ka mea, i kekahi hapa o kekahi o kekahi mau poe lehulehu o ka poe liilii, ano lani kahi revolving a puni ka honua o ka kekahi ala. I kā lākou mau hihia, i ka maikaʻi wā no ka pane-mai (manawa, e nana ana i ka lani, hiki koke maopopo mea mea he meteor) ua i ho'ākāka 'nani maikaʻi.

Roy i kēia mau makahiki he mea ua i kapaʻia he meteor auanei. Ma ka hapanui o na hihia, ka mea i hanaʻia i loko o ka make ana o ka comet nucleus. Kanaka huna kahawai e neʻe maila ia laua i kekahi i kekahi. Naʻe, i ka Honua i ka ili honua ia mea ia e kinoea ka mea, mai ka hana i ho'ākāka 'uuku wahi o ka lani. Keia wahi ua kapaia radiant koko. Ka inoa o ka meteor nalo, e like me ka rula, i haawi i ka huihui i loko i ka mea o ka pilikia makapō ioauoa (radiant) a ma ka inoa o ka comet, ka'opi o ka i alakai aku ai i kona helehelena.

Meteora, i mea oluolu, e kiʻi i kekahi Hawaii photo me ka hana lako e hai aku i na mea nui lua i pele i ka Perseids, Quadrantids keia -Aquarids, Lyrids, ka Geminids. Ka huina i ka lā, ka mea ike i ke ola ana o ka 64 kahawai, a ma kahi o 300 e kali ana e hooiaio ai.

lani pohaku

Meteorites, asteroids, meteors a me comets - e pili pū ana i loko o kekahi aoao ai kekahi i ka manaʻo o nā ana hoʻohālike. Ka mea mua o ka wa huakai i haule i ka Honua. Loa pinepine, ka mea, i ke kumu o asteroids, ma ka liʻiliʻi loa - he comet. Meteorites i pricelessʻikepili ma luna o nā wahi likeʻole o ka poe lń ma kela aoao o Honua.

Ka hapa nui o kēia mau kino i haule iho ai ma luna o mākou Honua, ka mea, i he uuku loa ka nui. Ka loa kilakila ma kona Ana meteorites haalele iho la ko läkou 'o ka hopena, ia mea kekahi', a ma hope o miliona o ka makahiki. Maopopo loa o ka lua kokoke i ke kulanakauhale o Winslow, Hawaii. I ka haule ana o ka meteorite i loko o ka makahiki 1908, allegedly, kena ae la ka Tunguska hanana.

Oia nui mea "e kipa i" ka Honua kela makahiki kakaikahi miliona. Ka hapanui o meteorites loaʻa nāʻano uku ma ka nui, akā, mai lilo i emi waiwai no ka 'epekema.

E like me kānakaʻepekema, i kēia mau mea ke hai aku i ka puu e pili ana i ka manawa o ke kahua o ka poe lń. Presumably, ka mea, he poe (particles) o ka mea i hana i ka mea opiopio Honua. Kekahi meteorites hiki iā mākou, mai Mars a me ka mahina. Oia cosmic aea ae e aʻo i kekahi mea hou e pili ana i ke kokoke mea ole nunui koina ma ka loihi mai kāna huakaʻi i.

I ka hoʻopaʻanaʻau i ka oko ao i ho'ākāka 'ia i loko o kēia' atikala hiki ia he lau o ka mea, e haawi i ka hou 'ana o ke kino i loko o ka lewa. Ke asteroid, oia no ka hana pohaku pohaku a comet, i mea he aeie ana o ka hau, i ka anai loa paha meteoroids i reentry Honua flare meteor, puhi i loko, a me ka hina ana, haliu ae la ia ma meteorites. Recent hoʻowaiwai i ko makou ike ana i ka mea mua ikaika.

Meteorites, comets, meteors, a me asteroids a me meteoroids - i komo o ke ana puni kalepa. I ka like o kēia mau mea lawe i na makana nui i ka hoomaopopo ana o ka ke ao holoʻokoʻa. Me ka hou o ka lako a pan no ka Astrophysics kiʻi 'ike hou aku e pili ana i kēia mau mea. Pau nei, "Rosetta" nuʻukiaʻimi maopopo nō ia i ka nui o 'ike hiki ke loaa ma ka piha study o kēia mau cosmic kino.
