Māhū-Neptunian mea: manaʻo, ano

Ma na outskirts o ko mākou poe lń o ka Kuiper kāʻei. He hele wale aku no Neptune ka Astronomical, ai kekahi palapala e ike i kekahi mea i loko o ia makahiki ua paʻakikī loa. Eia naʻe, like loa me ka loaʻa kanaka ikea mana telescopes, ka mea e hoʻokele i ka hana i kekahi discoveries. No ka laʻana, ka mea i ikeia e ia māhū-Neptunian mea - i ke kumu o ka mokuna o ka aha i ka Kuiper kāʻei, ka Oort ao , a hoopuehu aku iwi kuamoʻo. He He kokoke nana i ke kino ke kumukuai, kaʻapuni ana ma ka "Backyard" o ka poe lń.

TNO

Māhū-Neptunian mea - ka cosmic kino kaʻapuni a puni ke ao nei i loko o kona Astronomical. Ka loa kaulana o kēia mau mea - Pluto, noʻonoʻo i ka Honua a hiki i 2006. Eia naʻe, i ka lā, Pluto - i ka lua o ka nui loa māhū-Neptunian mea. Ka mamao i ka malamalama i loko o kēia mau kino, ua oi aku ia i na hoku a ma ko makou poe lń - Neptune.

Currently wehe oi ma mua o ka tausani ia mau mea. Eia naʻe,ʻepekema i kaʻaui i ka manaoio i ka mea, ua oi nui loa.

Ka nui loa māhū-Neptunian mea - Eris. Ua ua hamama i ka 2005. Ka loa loihi mai ka malamalama kino, i mea ole ka inoa, a uaʻikeʻia ma luna o ka papa inoa i helu V774104. Ua Ua wehe 'ia mai ke Sun ma 103 Astronomical Unit.

All TNO e māheleʻia i loko o eha pūʻulu.

hookaawale TNO

I ko kakou poe lń he mea he subclass o kēia 'ano o ke kino: kaʻawale mea. He kapa no ka mea, e, i ka olelo o ka perihelion o ia mau kino i ke aupuni 'ma ka nui kaawale mai Neptune, a nolaila i loli kona umekaumaha. Keia kahua i kēia mau hoku i kokoke kuokoa,ʻaʻole wale mai Neptune, akā, no hoi i ka pau o ka poe lń me ka a pau.

Technically, i kēia mau mea, he kino io hoopuehu aku ana pā hōkū. Currently,ʻikepili i loaʻa no ka eiwa o na kino, akā, i ka papa hoʻoneʻe 'ia paha i loko o ka wā e hiki mai kokoke e e me ka nui loa mahuahua.

Kekahi o na lala o keia hui TNO - Varuna. Wehe i loko o November 2000.

Panina Kuiper kāʻei mea

I ka inoa o keia pae ana o ke kino i hele mai, mai ka helu o ka mua o ia - QB1. Ia mea ke kumu o ka māhū-Neptunian mea, i ua aia i loko o ka Kuiper kāʻei, kapaʻia cubewanos (cue-ʻelua-Ouen). ʻO ka Astronomical o kēia mau mea moe ma kēlāʻaoʻao o ka Astronomical o Neptune, ko ka mea, ia lakou iho i kāheaʻia ka orbital resonance me ka Honua.

Nā orbits o ka hapanui o nā cubewanos i kokoke hoʻopoepoe kinona kokoke i ka ecliptic pelane. A nui loa o kēia mau kino i kaʻaui ma he uuku loa ka makau, ka mea'ē aʻe i ka nui k'ki pana pua, a me ka oi elongated orbits.

Ke kumu nui hiʻona o na kino no a hiki i keia pae i ka penei:

• Lākou mau orbits ole intersect ka Astronomical o Neptune.
• Mea i ole resonant.
• Lākou eccentricity - emi o 0.2.
• Lākou ana Tisserand ma mua o 3.

Classic Luna o keia pae - Quaoar, kekahi o na kino nui i loko o ka Kuiper kāʻei. Ua wehe i ka 2002.

resonant TNO

Resonant māhū-Neptunian mea i ka poe nona ka Astronomical mea i loko o orbital resonance me Neptune.

A kokoke like o kēia mau meaʻo ia ka mea e hiki ai, e olelo e pili ana i ka haiki o na palena o ka resonant mea. I ka manawa a noho i loko o kēia mau palena, i ke kino koi i kekahi dala o ka ikehu, ma neia hope aku a me ka ole emi. Hōʻoia i hele mai mai o ka Astronomical resonance, ia mea loa puni hoʻi: e like me ka moku haiahū kūmau o kalaka nui-nui (axis) o ka hoʻokumu palena.

E like me ka weheʻana o ka hou iauaeoia i loaʻa i oi ma mua o ka hapaʻumi o ia mea i loko o resonance 2: 3 me Neptune. Ua Ua manaoio aku ia ia i ka pilina ma mea ole accidental. Loa paha, i ohi mau mea ma Neptune ma ka Polenekia i oi loa orbits.

Ma mua o ka mea mua māhū-Neptunian mea, mākaukau manaʻo i ka hana o na kanaka nunui Honua ma ka i loko o ka papakaukau pā hōkū, e alakai i ka ka ho'ēmiʻana a me ka ulu i loko o ka hapa-laina weheia Dia kalaka nui-lipi o Uranus, Neptune, a me ka Saturn i.

Kekahi o na elele o keia pae mea he Orc - māhū-Neptunian mea, aia i loko o ka Kuiper kāʻei.

Puehu wale aku no iwi kuamoʻo mea

Kēia mea i ke kino i mea i loko o ka loa keʻena māhele o ko mākou poe lń. I ka pa apŘ o nā mea i loko o kēia wahi ka loa haʻahaʻa. A pau i ka hoopuehu aku ana iwi kuamoʻo kino i haku o ka hau.

Ke kumu o keia wahi i ole maoli kālaʻe. Ka hapanui oʻepekema mea ihola i ka manaoio i ka mea i hana i kekahi manawa, i ka wa o ka gravitational ole o ka Honua ma ka ikeia lawa ia ma luna o ka Kuiper kāʻei, no laila, i kona iauaeoia i liʻiliʻi lākou ma laila i ka mea nui wahi ma mua o kēia lā. Hele liilii pā hōkū, ua like kā i ka Kuiper kāʻei - he fickle Poakolu. Kino maloko hele ole wale i loko o ka "papamoe," kauoha, akā, i loko o ka "vertical", me kaʻaneʻane ka ia ka mamao. Kamepiula hōʻikeʻia nani ua hōʻike i i i kekahi o na mea he meandering ka Astronomical, hapa -. Lolelua ka Kēia i mea e hiki ai, e kuhi ana i ke kino hiki ke kuu i loko o ka Oort ao a me ka hailona hou.

hou Kaka

Ma July 2016 ka mea i loaʻa kekahi hou māhū-Neptunian mea. Kona Ana, ua uuku loa (anawaena - ma kahi o 200 km), ia mea 160 tausani manawa fainter ma mua o Neptune. Kona inoa ua unuhi mai Chineseʻano "kipi." Ua loaa mai i ka inoa o ka mea no ka mea ke ka ao ana ma ke ala e hiki aku e ku pono ana a hiki i ka neʻe o ka poe lń, e like me keia hiki ke wehewehe wale ma ka mea i kekahi i lawa ka ikaika kino, e ho ololi i ia, radically hoʻololi kona Astronomical.

Keia ano o ka hou hale mai i puʻe wale akula kēlāʻepekema no ka lilo, no ka mea, i ka manawa ia mea i maopopo mea o ka Honua, a pehea e hiki e ka "kipi" neʻe i loko o ia i ka Astronomical. Astronomers manaʻo hou e pili ana i ke ola ana o ka ike Honua, a hiki i ka mea o ka ikaika hopena ma luna o nā kino.
