He aha ka supermoon?Pehea ka hana ʻana o nā supermoons?

ʻO ka Supermoon (Supermoon) kahi huaʻōlelo i manaʻo ʻia e ka mea kilo hōkū ʻAmelika ʻo Richard Noelle i ka makahiki 1979. He mea ia e pili ana ka mahina i ka perigee i ka wā hou a piha paha ka mahina.Aia ka mahina ma ka perigee, puka mai ka mahina hou, ka mea i kapaia super New moon;piha pono ka mahina i ka wā ma perigee, i ʻike ʻia he mahina piha piha.No ka mea, e kaapuni ana ka mahina i ka honua ma ka orbit elliptic, e loli mau ana ka mamao ma waena o ka mahina a me ka honua, no laila, ʻoi aku ka kokoke o ka mahina i ka honua i ka wā e puka mai ai ka mahina piha, e ʻike ʻia ka nui o ka mahina piha.
Ua hoʻolauna ka poʻe loea ʻepekema Astronomy e ʻike ʻia kahi "super moon" i ka lani pō ma Iune 14 (Mei 16 o ka kalena lunar), ʻo ia hoʻi ka "mahina piha lua" i kēia makahiki.I kēlā manawa, ʻoiai ka maikaʻi o ke anā, hiki i ka lehulehu mai nā wahi a pau o ko kākou ʻāina ke hauʻoli i ka pōʻai o ka mahina nui, e like me kahi pā jade keʻokeʻo nani e kau ana i luna i ka lewa.
Aia ka mahina a me ka lā ma nā ʻaoʻao ʻelua o ka honua, a ʻokoʻa ka longitude ecliptic o ka mahina a me ka lā he 180 degere ʻokoʻa, ʻo ka mahina i ʻike ʻia ma ka honua ʻo ia ka pōʻai loa, ʻo ia ka mea i kapa ʻia ʻo "full moon", ʻike ʻia hoʻi. e like me "nānā".ʻO ka ʻumikumamāhā, ʻumikumamālima, ʻumikumamāono a hiki i ka ʻumikumamāhiku o kēlā me kēia mahina mahina, ʻo ia ka manawa e ʻike ʻia ai ka mahina piha.
Wahi a Xiu Lipeng, he lālā o ka Chinese Astronomical Society a me ka luna o ka Tianjin Astronomical Society, ʻoi aku ka "paʻa" o ka elliptical orbit o ka mahina a puni ka honua ma mua o ka elliptical orbit o ka honua a puni ka lā.Eia kekahi, kokoke ka mahina i ka honua, no laila aia ka mahina ma perigee.
I ka makahiki alemanaka, he 12 a 13 paha mau mahina piha.Inā kokoke ka mahina piha i ka perigee, e ʻike ʻia ka mahina nui a poepoe i kēia manawa, i kapa ʻia ʻo "supermoon" a i ʻole "super full moon".ʻAʻole maʻamau ka "Supermoons", mai hoʻokahi a ʻelua paha i ka makahiki a ʻekolu a ʻehā paha i ka makahiki.ʻO ka "mahina piha nui" o ka makahiki ke hiki mai ka mahina piha i kahi kokoke loa i ka manawa o ka mahina i perigee.
ʻO ka mahina piha i ʻike ʻia i ka lā 14 o Iune, ua ʻike ʻia ka manawa piha ma 19:52, ʻoiai ua perigee loa ka mahina ma ka hola 7:23 o Iune 15, ʻo ka manawa pōʻai a me ka manawa perigee ʻaʻole i emi iho ma mua o 12 hola, No laila, ua He nui loa ke anawaena o ka ili o keia mahina piha, a aneane like me ka "mahina piha loa" o keia makahiki.Hōʻike ʻia ka "mahina piha nui" o kēia makahiki ma Iulai 14 (ka lā ʻumikumamāono o ka mahina ʻeono).
"Ma hope o ka hāʻule ʻana o ka pō i ka lā 14, hiki i nā poʻe hoihoi o ka lehulehu mai nā wahi a pau o ko mākou ʻāina ke hoʻolohe i kēia mahina nui i ka lani o ka pō a hauʻoli me ka maka ʻōlohelohe me ka ʻole o nā lako hana."Ua ʻōlelo ʻo Xiu Lipeng, "ʻO ka mahina piha liʻiliʻi loa o kēia makahiki i loaʻa i Ianuali o kēia makahiki.Ma ka lā 18, inā ua kiʻi kekahi kanaka me ka manaʻo i ka mahina piha i kēlā manawa, hiki iā ia ke hoʻohana i nā mea hana like a me nā ʻāpana like o ka lōʻihi e kiʻi hou ai ke kiʻi hou ʻia ka mahina ma ke kūlana hoʻohālikelike like.Pehea ka 'nui' o ka mahina piha.
