Kāʻei Kuiper

kāʻei kuiper

Ua ʻike mākou ʻaʻole e pau pololei ka ʻōnaehana solar ke hala mākou i ka orbit o ka honua Pluto. Hoʻonui iki kēia ʻōnaehana solar e ka kāʻei kuiper. No ka hiki ʻana i laila, pono mākou e hele i kahi mamao loa ma waho o Neptune a me Pluto. I kēia manawa, ʻo Arrokoth (2014 MU69) ka mea mamao loa i loaʻa i kahi mokulele. Aia ma kahi i ʻimi ʻia ai, aia kahi ʻāpana o ka ʻōnaehana solar i ke anuanu a me ka pōʻeleʻele a kapa ʻia ʻo ke kāʻei Kuiper. Aia kona koʻikoʻi ma ka ʻoiaʻiʻo aia nā kī e hoʻomaopopo ai i ke ʻano o ka hana ʻana o ka ʻōnaehana solar.

No laila, e haʻi mākou iā ʻoe i nā mea āpau e pono ai ʻoe e ʻike e pili ana i ke kāʻei Kuiper, kona ʻano a me kona kumu.

He aha ke kāʻei Kuiper

kāʻei kuiper i ke ao holoʻokoʻa

ʻO ke kāʻei Kuiper kahi ʻāpana ʻano donut (i kapa ʻia ʻo Tor ma geometry) i loko o nā miliona mau mea paʻa paʻa hau. Kapa ʻia kēia mau mea he mau mea kāʻei Kuiper.

He wahi kēia i hoʻopiha ʻia me nā miliona o nā kino lani i hiki ke hoʻokumu i nā hōkūhele, akā naʻe, ʻo ka ʻumekaumaha o Neptune ua hoʻopuehu i kēia lewa. ka pale ʻana i kēia mau kino lani liʻiliʻi mai ka hui ʻana e hana i kahi honua nui. Ma kēia manaʻo, ua like ke kāʻei Kuiper me nā asteroids nui e hoʻopuni ana iā Jupiter ma ka ʻōnaehana solar.

Ma waena o nā kino lani i ʻike ʻia ma ke kāʻei Kuiper, ʻo ka mea kaulana loa ka honua dwarf Pluto. ʻO ia ke kino lani nui loa ma ka Kuiper Belt, ʻoiai ua ʻike koke ʻia kahi honua dwarf hou (Eris) like me ka nui ma ka Kuiper Belt.

A hiki i kēia lā, ʻo ke kāʻei Kuiper ʻO ia ka palena ʻoiaʻiʻo o ka lewa, ʻike liʻiliʻi a ʻimi ʻia. ʻOiai ua ʻike ʻia ʻo Pluto i ka makahiki 1930 a ua wānana ʻia kahi kāʻei o nā mea hau ma waho o Neptune, pono e hoʻomaopopo ʻia ua ʻike ʻia ka asteroid mua ma kēia māhele o ka ʻōnaehana solar i ka makahiki 1992. Pono ke aʻo ʻana a me ka ʻike o ka Kuiper Belt. e hoʻomaopopo i ke kumu a me ka hoʻokumu ʻana o ka ʻōnaehana solar.

Kumukanawai o ka Belt Kuiper

wahi hope o ka ʻōnaehana lā

I kēia manawa, ua helu ʻia lākou ʻoi aku ma mua o 2.000 mau kino lani i ke kāʻei Kuiper, akā, hōʻike wale lākou i kahi hapa liʻiliʻi o ka huina o nā kino lani ma kēia māhele o ka ʻōnaehana solar.

ʻO nā mea o ke kāʻei Kuiper he comets a me asteroids. ʻOiai ua like lākou, ʻokoʻa ka haku mele a me nā asteroids. He kino lani ko Comets me ka lepo, nā pōhaku, a me ka hau (gasua hau), aʻo nā asteroids i hana ʻia me nā pōhaku a me nā metala. ʻO kēia mau kino lani he koena o ka hoʻokumu ʻana o ka ʻōnaehana lā.

ʻO ka nui o nā mea hana i ka Kuiper Belt he mau ukali e hoʻopuni ana iā lākou, a i ʻole nā ​​mea binary i hana ʻia me ʻelua mau mea like ka nui, a ʻo ka orbit a puni kahi kiko (waena maʻamau o ka nuipaʻa). Pluto, Eris, Haumea a me Quaoar kekahi mau mea lawe mahina ma ke kāʻei Kuiper.

I kēia manawa, ʻo ka nui o nā kino lani i hoʻokumu ʻia i ke kāʻei Kuiper he 10% wale nō o ka nui o ka Honua. Eia naʻe, ua manaʻo ʻia he 7 a 10 ka nui o ka nui o ke kāʻei Kuiper ma mua o ka honua. i hana ʻia mai 4 mau hokele nunui (Jupiter, Saturn, Uranus a me Neptune).

Nā kumu o ka emi ʻana o ka pohō nui

asteroids i ke ao holoʻokoʻa

ʻO nā mea i loaʻa ma ke kāʻei Kuiper i kapa ʻia ʻo KBO. ʻO ka lilo ʻana o ka nuipaʻa i loko o kēia kāʻei lani hauʻoli ma muli o ka ʻai ʻana a me ka luku ʻana o ke kāʻei Kuiper. ʻO nā comets liʻiliʻi a me nā asteroids i hoʻokumu ʻia e hui pū kekahi me kekahi a māhele ʻia i mau KBO liʻiliʻi a me ka lepo, i puhi ʻia a i ʻole i loko o ka ʻōnaehana lā e ka makani lā.

I ka pau ʻana o ke kāʻei Kuiper, ua manaʻo ʻia kēia wahi o ka ʻōnaehana solar kekahi o nā kumu o nā comets. ʻO kekahi ʻāina kumu no nā comets ʻo ke ao Oort.

Hoʻokumu ʻia nā Comets ma ke kāʻei Kuiper i ka wā i hoʻokumu ʻia ai nā ʻōpala ma hope o ka huki ʻana o KBO i loko o ka ʻōnaehana lā e ka gravity o Neptune. Hoʻokumu ʻia nā Comets ma ke kāʻei Kuiper i ka wā i hoʻokumu ʻia ai nā ʻōpala ma hope o ka huki ʻana o KBO i loko o ka ʻōnaehana lā e ka gravity o Neptune. I ka huakaʻi i ka lā, ua paʻa kēia mau ʻāpana liʻiliʻi i loko o kahi orbit liʻiliʻi e ka umekaumaha o Jupiter, kahi ʻaʻole i ʻoi aku ma mua o 20 mau makahiki. Ua kapa ʻia lākou he comets wā pōkole a i ʻole comets o ka ʻohana Jupiter.

Aia ma hea ia?

E like me kā mākou i ʻōlelo mua ai, aia ka Kuiper Belt ma ka ʻaoʻao o waho o ka ʻōnaehana solar, ʻo ia ka orbit o Pluto. ʻO ia kekahi o nā ʻāpana nui loa o ka ʻōnaehana solar. Aia ka lihi kokoke loa o ke kāʻei Kuiper ma ka ʻōpuni o Neptune, ma kahi o 30 AU. (ʻo AU ka ʻāpana hōkū o ka mamao, e like me 150 miliona kilomika, ʻo ia ka mamao ma waena o ka Honua a me ka Lā), a ʻo ke kāʻei Kuiper ma kahi o 50 AU mai ka lā.

Hoʻopili hapa ʻo ia i ke kāʻei Kuiper a hoʻolōʻihi i kahi i kapa ʻia ʻo Scattering Disk, kahi e lōʻihi ana ma kahi mamao o 1000 AU mai ka lā. ʻAʻole pono e huikau ke kāʻei Kuiper me ke ao Oort. Loaʻa ke ao Oort ma ka ʻaoʻao mamao loa o ka ʻōnaehana solar, ma kahi mamao loa, i manaʻo ʻia aia ma waena o 2000 a 5000 AU mai ka lā.

Hoʻokumu pū ʻia me nā mea hau e like me ke kāʻei Kuiper, i hana ʻia e like me ka pōʻai. Ua like ia me ka pūpū nui, i loko o ka lā a me nā hōkūhele a me nā kino lani a pau i hana i ka ʻōnaehana solar, me ke kāʻei Kuiper. ʻOiai ua wānana ʻia kona ola ʻana, ʻaʻole i nānā pono ʻia.

Manaʻo wau me kēia ʻike ua haʻi ʻoe i ke kāʻei Kuiper, nā ʻokoʻa me ke ao Oort a aʻo hou e pili ana i ko mākou ao.


Hoʻopili ka ʻike o ka ʻatikala i kā mākou kumumanaʻo o ka hoʻoponopono hoʻoponopono. E hōʻike i kahi kaomi hemahema ʻaneʻi.

E lilo i mea mua e wehewehe

E waiho i kāu manaʻo

Kāu leka uila aae? E,ʻaʻole e paʻiʻia.
