Yintoni planethi zikude kwinkqubo solar?

Ukongeza Umhlaba, kukho kwinkqubo solar, enye iplanethi oluhlaza - Neptune. Ngowe-1846 kufunyaniswe ngenxa ukubala imathematika kunokuba mkhanya.

Yintoni planethi zikude kwinkqubo solar ukusuka eLangeni?

Ngowe-1930, iPluto yavulwa. De kwango-2006, yena ingqalelo emhlabeni yesithoba yokugqibela kwinkqubo elanga. Nangona kwabanye - kuphela wesibhozo. Noko ke, ngo-2006 i-International Astronomical Union iye anikwe intsingiselo entsha elithi 'umhlaba' iPluto akazange kuwa phantsi kwayo. Kukho iinguqulelo nkqu ukuba akakulandeli kwinkqubo solar, kwaye iyinxenye Kuiper Belt.

Kwakhona, le isihloko, yena anqunyulwe ukususela 1979 ukuya 1999, ngeli xesha, iPluto waba ngaphakathi komzila planethi Neptune.

Ngoko ke, ekuphenduleni lo mbuzo: "Ngubani na ke umhlaba zikude langa" - ukuba weva njenge impendulo amagama amabini.

Kwabanye kwiintsomi eRoma na uthixo yolwandle.

lokufumanisa

Ngokusemthethweni emhlabeni zikude kakhulu System yethu Solar - Neptune - lwafumaneka ngo-1846. Noko ke, ngo-1612 oko kwachazwa UGalileo. Kodwa ke ingqalelo yakhe inkwenkwezi esingatshintshiyo, kutheni azikhange zikhunjulwe discoverer yayo.

Ubukho iplanethi entsha engekamithwa-1821, xa ekupapashweni utshintsho data kwi komzila Uranus, leyo zazahlukile amaxabiso kule theyibhile.

Kodwa kuphela komzila Septemba 23, 1846, emva kweenyanga ezimbini sifuna, ngokusebenzisa izibalo kwabanye yafunyanwa.

Igama lakhe wamkela ngenxa kwimathematika, wayivula (W. Leaver), obefake wayefuna ukuba igama emhlabeni emva kwakhe.

Yintoni planethi zikude kwinkqubo solar? incazelo

Kwabanye ziqhubela sokuvalwa ngorhatya. yokucacisa wayo amaxesha 900 ngaphantsi kunolo iplanethi yethu. Sun evela orbit ubonakala nje inkwenkwezi eliqaqambileyo.

It is a ingxilimbela kumgama 4,55 billion khilomitha, okanye malunga 30. . E inobunzima izihlandlo 17.15 ezinkulu kuno Earth kunye ubukhulu - 4 amaxesha ngaphezulu. avareji density sayo ngamaxesha kuphela isiqingatha izalathi si zokunikwa amanzi (1.6 g / cu. Cm). Ngoko ke, kwabanye libhekisela kwiqela iiplanethi ezinkulu, nayo leyo iquka likaSaturn, uJupiter Uranus.

Iplanethi mba kwinkqubo elanga nayo ngokuba umkhenkce, kuba ubunzima helium yehayidrojini kumafa yayo ayikho ngaphezu kwe-15-20%.

Njengezinye iingxilimbela, nguNeptune ngesantya kakhulu esijikelezayo kwi axis yayo. Usuku yakhe iiyure 16.11 kuphela. Ehlabathini ilanga, wenza uguquko orbit phantse setyhula iminyaka 164,8. Ngo-2011 wagqibezela revolution yakhe yokuqala ngokupheleleyo ukususela lokuvula.

Phezu weNeptune yimimoya enamandla kuphumelela, ngesantya avareji apho - 400 m / umzuzwana.

Okubangel 'umdla kukuba, iqondo lobushushu umhlaba yeyona - 214 C ukuba xa asezantsi kakhulu. Yinto eyaziwayo ukuba uninzi planet elikude inkqubo elanga eyakhe umthombo wayo ubushushu ngaphakathi, ekubeni amaxesha 2.7 amandla ngaphezulu obubonakala emajukujukwini kunokuba lubamba ukusuka elangeni.

Ngomhla iplanethi njalo kwi tshintsho onyaka. Elinye ixesha ithatha iminyaka 40.

satellites

Iplanethi mba kwinkqubo elanga satellites-14. Kaninzi bohlulwa babe ngamaqela amathathu:

- yangaphakathi: Talas, Naiad, Galatea, Despina, Larissa, Proteus;

- ngokwahlukileyo ukubeka Nereid and Triton;

- satellites ezintlanu amazwe kuba akukho gama.

Iqela lokuqala luquka lutyhido ezimnyama efikelela 100-200 km nokuba i imilo ezitenxileyo ezinokwenzeka. Ukuba ukujikeleza a emzileni Isetyhula phantse-ikhweyitha. Zihlala kuwo wonke umhlaba kwiiyure nje ezimbalwa.

Iqela lesibini liquka Triton. Le Isathelayithi enkulu kangangoko. Ubukhulu bayo - malunga 2,700 km, ingeniso epheleleyo malunga abanjengoNeptune ngayo iintsuku ezi-6. Ahamba, ngokucotha esondela umhlaba. Xa libetha kwabanye yaye phantsi kwempembelelo imikhosi ngamaza nisinga kwesinye isangqa. kumphezulu wayo iyabanda, kukholelwa ukuba ngaphantsi kwe ice uqweqwe lwadamba olwandle.

Nereid ejikelezayo isigebenga iintsuku 360. Ine- imilo ezitenxileyo ezinokwenzeka.

Hewana bangaphandle ukwindawo ekude (amashumi ezigidi ngeekhilomitha) ukusuka kweneptune. Uninzi iimpukane kude ehlabathini jikelele iminyaka engama-25. Xa ucinga orbit utyekelo lwabo kwi-moya sentshinyela kunye nentshukumo umva, kwagqitywa ukuba kwikhompyutha yi abanjengoNeptune kwi Kuiper izinto bhanti.

satellite lokugqibela lavulwa ngoJulayi 2013.

Kwabanye uye amakhonkco ezintlanu ice ngamasuntswana. Ezinye zazo iqanjwa carbon, ukuze wenze ebomvu. Bona zithathwa kuba eselula kwaye elifutshane elide. Amakhonkco weNeptune iyahlozinga enkulu ezahlukeneyo enye kwenye.

anika umdla

Ukuphendula umbuzo malunga ku iiplanethi ezikude isiphekepheke langa ezaziwayo "Voyazhder 2" yasungulwa ngayo, kunokuthiwa ukuba ekuqaleni wayethunywe ukufunda uJupiter likaSaturn, kodwa indlela sikuphumezileyo njengoko Uranus noNeptune. It yasungulwa ngo-1977.

Agasti 24, 1989, moya ngo-48 amawaka. Km weNeptune. Ngeli xesha, i-Umhlaba ziye zathunyelwa imifanekiso yomhlaba kanye satellite yayo Triton.

Ngowe-2016 kwacetywa ukuthumela kwenye kwisiphekepheke emhlabeni. Noko ke, ngalo mzuzu umhla sungula ngqo ayikho.
