Poepoe Honua

ʻO ka Honua (ka inoa Pelekania: Honua) ke kolu o ka Honua mai loko a ma waho o ka ʻōnaehana lā. ʻO ia hoʻi ka honua honua nui loa i ka ʻōnaehana o ka lā e pili ana i ke anawaena, ka nui, a me ka nui. Aia ma kahi o 149.6 miliona mau kilomita (1 astronomical unit) mai ka lā. Hoʻohuli ka honua mai ke komohana a i ka hikina ʻoiai e puni ana ka lā. I kēia manawa he 4,55 biliona mau makahiki, aia ka honua i kahi ukali maoli-ka mahina, a hana nā mea ʻelua i kahi ʻōnaehana lani-ka ʻōnaehana moon-moon. Ua hoʻomaka ʻia i ka nebula solar primordial 4.55 biliona mau makahiki i hala.
ʻO ka radius equatorial o ka honua 6375.137 kilomika, ʻo ka radius polar he 6356.752 mau kilomika, ʻo ka radius radius ma kahi o 6371 kilomita, a ʻo ke kaʻe kaulike e pili ana iā 40075 kilomita. He ellipsoid kaulike ʻole ia me nā pou i pālahalaha iki ʻia a me ka equator e hoʻokuʻi iki ʻia. Aia ka ʻili o ka honua he 510 miliona mau kilomika kilomika, a nona kēia 71% ka moana a he 29% he ʻāina. Ke nānā ʻia mai kahi ākea, he uliuli ka honua. Hoʻokomo ʻia ka lewa i ka nitrogen a me ka oxygen, a me kahi ʻāpana o ke kalapona a me ka argon.
Hoʻokaʻawale ʻia ka loko o ka honua i ke kumu, ka ʻahu, a me ka ʻaʻai o ka pā, a aia kekahi hydrosfos, ka lewa a me ka mālamana ma waho o ka honua. ʻO ka honua wale nō ke kino lani i ʻike ʻia e noho nei i ke ao holoʻokoʻa, a he home ia no nā mea ola he miliona me nā kānaka like ʻole.
