UMUBUMBE WA NEPUTUNE(NEPTUNE)

Umubumbe wa Neptune ni uwa munani uva ku zuba mu buryo bw’urukurikirane rw’imibumbe y’ikirere. Ni umwe mu mibumbe minini cyane (gas giant) ndetse ugizwe ahanini n’ibinyabutabire bitandukanye birimo gaz. Dore ibintu by’ingenzi wakamenya kuri Neptune:

Ibintu by’ingenzi ku bijyanye na Neptune

Imiterere rusange

• Umwanya: Umubumbe wa munani, uherereye kure cyane y’Izuba.
• Ubunini: Ufite ubunini bungana hafi 4 ikubye ubw’Isi.
• Uburemere: Ufite uburemere buruta ubw’Isi inshuro 17.
• Icyegeranyo: Cyibanda kuri gaz nka:
  • Hydrogène (H₂)
  • Hélium (He)
  • Methane (CH₄) — itanga ibara rya buluu.

Ikirere n’ibihe kuri Neptune

• Umuyaga mwinshi: Neptune ifite umuyaga ukaze cyane ku mubumbe uwo ari wo wose — ushobora kugera kuri 2,100 km/h.
• Ibihe bibi cyane: Ifite imiyaga minini, imvura ya diamonds (mu ntekerezo), n’imiyaga imeze nk’inkubi z’imvura.
• Ubushyuhe: Buri hasi cyane, bugera kuri -214°C.

Ibiranga bidasanzwe

• Dark Spot (Icyari cy’Umukara): Hari “ikizinga cy’umukara” cyabonetse bwa mbere n’icyogajuru Voyager 2 mu 1989, kiri nk’urubura rurimo umuyaga mwinshi.
• Imirongo (rings): Ufite imirongo mito itagaragara cyane, isa n’iya Saturn, ariko yoroheje.

Ubushakashatsi bwa muntu

• Voyager 2: Ni cyo cyogajuru cya NASA cyasuraga Neptune mu 1989, gitanga amafoto ya mbere ya hafi.
• Ibindi bikoresho: Nta kindi cyogajuru kirahasurwa; amafoto menshi dukoresha ubu aturuka ku matelescopes yo ku Isi no mu isanzure (nk’iya Hubble).

Utubumbe twayo

• Ufite utwenda 14 tumenyerewe, duto cyane ugereranyije n’utw’indi mibumbe.
• Triton: Ni kamere nini cyane muri two, ikaba yihariye kuko igenda mu cyerekezo gitandukanye n’icya Neptune — bikavuga ko ishobora kuba yaratwawe iva ahandi.

Ibindi bitekerezo by'ingenzi

• Neptune ntiyabonetse n’amaso ya muntu bwa mbere, ahubwo yabazwe (predicted) mu 1846 n’abahanga bagendeye ku bikurura by’indi mibumbe (Uranus).
• Ni umubumbe urema cyane ugereranyije n’indi mibumbe ya gaz (gas giants).
