He aha ka ʻōnaehana o ka Pōkuhi, nā Hālāwai ma ka Pūnaehana Kūʻai a me nā ʻenehana o nā Pōkuhi

Pehea ka ʻōnaehana o Suria? ʻO ka ʻike ʻōnaehana Pūnaewele
Wahi a nā noiʻi, ʻoiai ʻaʻole ʻike ʻia ka makahiki kikoʻī o ka lā, ua manaʻo ʻia ma kahi o 5 biliona mau makahiki. Ke nānā mākou i nā mea i loko o kāna ʻike, ʻike mākou ke hui pū ʻia mai ka helium a me ka hydrogen gas. ʻO 332.000 mau manawa kona kaumaha i ka nui o ka honua. Ua ana ʻia ka mamao ma waena o ko mākou Honua a me ka lā e like me 149.500.000. ʻO ka lā, kahi kumu nui o ka ikehu, hoʻopau i kāna kaʻapuni iā ​​ia iho i nā lā he 25 wale nō. E like me ka 600 miliona hydrogen i hoʻohuli ʻia i helium i kēlā me kēia kekona, loaʻa kahi mahana o 6.000 C. Wahi a nā manaʻo ʻepekema i kēia manawa, ʻo ka mahana i hoʻokumu ʻia ma waena he 1.5 miliona C. Lawe nā kukuna o ka lā ma kahi o 8 mau minuke a hiki i ka honua.

Pehea ka ʻōnaehana o Suria?

ʻOiai ka ʻike ʻia o ka lā e ka nui o ka honua, he hōkū maoli ia. Aia nā hoʻolālā 9 a me nā kino lani he nui i nā orbits a puni ka lā. Ka papa pae honua i loko o ka pūnaehana solar; Mercury, Venus, Honua, Mars, Jupiter, Saturn, 'Uranus, Neptune. ʻO ia nō ʻo Pluto, i ʻike ʻia ma 2006, ua komo i loko o kēia papa inoa. Akā ua ʻōlelo ʻia ʻo Pluto ma kahi honua honua hōkū. Kuhi ʻia hoʻi he mau helu kipa ʻole i loko o ka ʻōnaehana panina e like me kēia mau papa. ʻO ka ʻōnaehana hana hoʻohālikelike o ka Milky Way Galaxy. I loko o ka Milky Way Galaxy, ʻike ʻia ʻo 90 ka nui o nā hōkū 100 bilela, ka mea i manaʻo ʻia e like me ka lā. ʻO ka Milky Way Galaxy wale nō, manaʻo ʻia ʻo 1 e kokoke loa i kahi paniliona trillion.
Huli nā ʻōiwi a pau o nā honua āpau a puni nā ʻōnaehana o ka lā i kekahi orbit ma muli o ka nui o ka lā.

Papa hoʻolālā i ka Pūnaewele Kūʻai

I ka manawa e hoʻokau pono ʻia nā lua i loko o ka pōleʻa o ka lā, ua hoʻokolokolo ʻia ma nā ʻāpana ʻelua e like me ka hoʻolālā kino a me ka terrestrial. Nā papa hana me nā ʻōnaehana terrestrial; Mercury, Venus, Honua a me Mars. Nā hoʻolālā honua me nā kāpena gaseous; Jupiter, Saturn, Uranus a me Pluton. ʻO nā hiʻohiʻona o nā planeta i ka hoʻonohonoho o ka lā, penei:
Mercury: ʻO Mercury ka honua kokoke loa i 58 mai kahi o kahi he miliona mile ka mamao o ka lā. Ma muli o kahi kokoke i ka lā, hiki i ka mahana ākea ke piʻi i 450C. ʻO ka puʻuwai gravity o Mercury ka 1 / 3 o ka mana gravitational o ka honua.
Venusa: ʻO Venus, ka lua o ka papa honua kahi kokoke i ka lā, he hoʻokahi miliona mile ka mamao mai ka lā. Ke nānā ʻia ai ka radius, ʻike ʻike ʻoe i kāna mau ʻāpana ma aneane i ka pae like o ka honua. Ke hoʻopau nei ka wili a puni ka lā i 108.4 mau lā a huli i ka ʻaoʻao kūlike o nā pelekane ʻē aʻe.
World: ʻO ke kolu o ka Honua kahi kokoke i ka lā, ʻo ka mamao ma waena o ka Honua a me ka lā he 149 miliona mau kilomita. ʻO ka mamao o ka honua he 12 mau tausani kilomita 756. ʻO ka wili piha e puni ana i ka lā e hoʻopau ai i nā lā 365 5 mau hola 48 mau minuke 23. Ke hoʻopau nei kona luli ʻana i kāna e koi ai i loko o nā hola 56 4 mau minuke XNUMX. Hoʻokumu ʻo ia i ke ao a me ka pōholi i kona wili a puni iā ​​ia, a hoʻokumu i nā kau ma o ka huli ʻana i ka lā.
Mars: ʻO ka honua kokoke loa i ka lā, Mars, ka mamao ma waena o ka lā a me ka 208 miliona mau kilomita. Loaʻa ia i ka ikaika gravitational o 40% o ka mana gravitational o ka honua a ʻo kāna kahe ʻana he 3 tausani 377 mau kilomita. E hoʻopau ana ka luli a puni ka lā ma 24 mau hola 37.
Dia: Me kona mau hapa hapa o 71 mau tausani mile 550, hiki iā mākou ke ʻōlelo ʻo Jupiter ka honua nui loa i kaulana ma ka pūnaehana solar. ʻO ka nui o ka Jupiter e like me ka manawa 310 o ko mākou honua. ʻO ka mamao o ka mamao o ka lā he 778 mau kilomita. ʻO ka lili ʻana a puni ka lā 12 e hoʻopau i kona wili a puni ke koena i ka makahiki.
Saturn: Me kahi mamao o 1.4 biliona mau kilomita mai ka lā, aia i ke ono o ka mamao i ka lā. Loaʻa i loko o laila ka hydrogen a me ka helium. ʻO ka radius o ka honua 60 398 10 mau kilomita. ʻOiai hoʻopau ʻo ia i kāna kaʻapuni a puni kāna axis ponoʻī i 29.4 mau hola, hoʻopau ia i kāna kaʻapuni a puni ka lā i nā makahiki XNUMX. He apo ko Saturn i hana ʻia i nā pōhaku a me ka hau.
Uranus: ʻO Uranus, kahi o ka honua kahi e kokoke loa ana i ka Honua, ma kahi o ka aniani mau mile ka mamao mai ka lā. ʻIke mākou i nā manawa 2.80 ka nui ma mua o ka honua. Hoʻopau ʻo 100 i kona loli i ka lā i hoʻokahi makahiki. Aia ia i ka hui pū ʻana o ka helium, hydrogen a me ka methane.
Neptune: ʻO 4.5 billion mau mile ka mamao mai ka lā ka ʻewalu o ka honua ma kahi mamao loa. Hoʻopiha ʻo 164 i kona kaʻe i puni ka lā i loko o ka makahiki, ʻo 17 ka hoʻopiha pono i kona wīwī a puni ka hola. Ua ʻike ʻia aia ʻo kahi satelona 13.
Pluto: ʻO 6 i ka lā kekahi o nā planeta lōʻihi loa a me kahi pālua miliona mau mile. Hoʻololi ʻo Pluto a puni ka lā i ka makahiki 250, ʻoiai ke kaʻe ʻana a puni kona koi o ke koʻi koi ʻana ma 6 mau hola 9 mau hola 17. ʻO ia ka mea i kūkulu ʻia o ka hau a me ka methane, ke ʻano o ka hāalulu.

ʻO nā waiwai o nā Pōhaku ma ka Pūnaehana Kūʻai

He mau hiʻohiʻona nā hoʻolālā i loko o ka pūnaehana solar. Ma waena o kēia mau hiʻohiʻona, ua ʻōlelo pōkole mākou i nā wehewehe o nā panie. ʻO nā hiʻohiʻona ʻē aʻe o nā papa hoʻolālā:
Loaʻa nā hoʻolālā āpau i nā wikiwiki rotational like.
Loaʻa nā hoʻolālā āpau i nā elliptical āpau. Hiki iā ʻoe ke ʻike i ke ʻano o nā orbits o nā papa honua i kēlā me kēia, ʻoiai ke ʻano ka ʻokoʻa o nā wikiwiki.
- E huli ka lua honua mai ke komohana a i ka hikina a puni ka lā a i loko o ko lākou mau lipi.
ʻO ka honua ka nui ʻo Jupiter a ʻo ka honua honua ʻo Pluto.
ʻO ka Mercury ka honua kokoke loa i ka lā. ʻO ka honua kahi mamao loa i ʻike ʻia ʻo Pluto.
ʻIke ʻia ʻo Venus ka honua kokoke loa i ka Honua i nā ʻōlelo o ka radius a me ka mamao.
ʻAʻohe mahina no ka Mercury a me Venus. He mahina ka 1 honua, ko Mars a me Neptune nā 2 moona, nā mahina ʻo 6 a Uranus, nā mahina ʻo XRUMUMX a Saturn, a me nā mahina 10 o Jupiter.
-ʻO ka ʻoi ʻana o ka loli o ka hoʻolālā honua e kūlike me kahi mamao loa mai ka lā.

Pehea ka sateline o ke ao?

Ua haʻi mākou iā ʻoe he hōkū ke Sun. Aia ka ʻōnaehana o ka lā, ka ʻaoʻao o ka lā, nā planeta e kū ana a puni, a me nā satelite o kēlā mau papa. I kēia ʻāpana, ʻike kā kekahi i ka manaʻo, ʻo ka honua a i ʻole ka mahina o ka lā. ʻAʻohe mea penei. ʻAʻole kinona ka honua akā he honua. ʻO ka mahina ka kahi o ka honua.

Kūleʻa o nā Pōhaku i ka Pūnaehana Kūʻai

Ua ʻōlelo pū mākou ua loaʻa kekahi mau satellite ma luna o ka ʻōnaehana o ka lā. ʻO nā hoʻolālā a me kā lākou mau satelite:
Mercury: ʻAʻohe satelika.
-Venüs: ʻAʻohe satelika.
World: ʻO ke kikowaena ka Moon. ʻO ka Pōʻalima ka ʻelima nui loa o ka ʻōnaehana o ka lā. Ke nānā nei mākou i ka diameter, ʻike mākou ua like ka nui o ka honua e like me ka 27%. ʻO ka kaʻe o ka mahina e like me ke kūlike o 6 i ka honua. No laila, eia kekahi o ka honua i loaʻa ka 1 kg ʻo 60 kg i kēlā me kēia mahina.
Mars: ʻEko ʻelua mau satelika ma Mars. ʻO kēia mau huahelu o:
-Phobos: ʻO kona mamao ma Mars he 6 tausani mau kilomita. ʻO ia kekahi o nā satelite kūlohelohe maoli i loko o ka ʻōnaehana o ka lā. Loaʻa iā lākou kahi kahi hana kawehi a ʻaʻole like i ka Moon i ka manawa āpau.
-Deimos: I ka ʻoiaʻiʻo, ua manaʻoʻiʻo ʻia kēia satelinaka a me Phobos o Mars i ka komo ʻana i ka ikaika gravity o Mars. ʻO ka mamao mai Mars a 20 hoʻokahi tausani mau kilomita. ʻO ka awelika o ka satellite 13 tausani mau kilomita.
Dia: Loaʻa ʻo Jupiter i nā mahina ʻo 4. ʻO kēia mau huahelu o:
—Uaa PūUa: ʻO ka mea kokoke loa iā Jupiter ka pūnaewele. He lua pele e kulu ana i ka hau a me ka lava ma ka satellite.
-Europa Pūnaewele: ʻO ia ka lua o ka hāmeʻa kokoke loa iā Jupiter. ʻO 3000 ka makahiki kilomita.
-Kūwili Lio:  ʻO ia ke kolu o ke kikowaena kokoke loa iā Jupiter. ʻO ia ka uila nui loa ma ka ʻōnaehana o ka lā.
—UwelaUwali: ʻO ka lua o ka satelona nui loa o Jupiter a me kahi mamao loa iā Jupiter.
Saturn: ʻEkolu mau mahina a Saturn. ʻO kēia mau huahelu o:
—Tūwili Pūnaewele: ʻO ka lua ka lua o ka hāmeʻa nui i loko o ka ʻōnaehana o ka lā. He wahi anuanu kūpono.
-Rūwela Pūnaewele: Hoʻopau ia ma Saturn e like me ka malama hoʻokahi. Loaʻa kona ʻano kahiko.
-Mela Pūnaewele: Loa ʻia e William Herschel ma 1789. Hoʻokumu ʻia ka mokuahi ma muli o ka pohō nui.
Uranus: ʻO nā hua ʻōlelo o Uranus he:
–Ariel Pūnaewele: Loaa ia na William Lassel ma 1856. ʻO ka radius ka 1190 mau kilomita.
–Miranda Pūnaewele: Loaa ʻia ia e Gerard Kuiper ma 1948. He ʻokoʻa nā hiʻohiʻona papa o nā papa hana a me nā satelite.
