Te whakamāramatanga o te karu tiro whetū
Ko ngā karu tiro whetū, ko ngā karu tiro whetū rānei, he taputapu whatu e whakamahia ana hei āwhina i te kanohi ki te kite i ngā mea o te rangi pērā i ngā whetū, ngā aorangi, ngā amiorangi, me ētahi atu. Ahakoa te rahi o ngā mea o te rangi, he tawhiti rawa te tawhiti o ngā mea o te rangi, ā, ina tirohia mā te whakamahi i ngā kanohi, ka āhua iti ngā tinana o te rangi. Ko te mahi a ngā karu tiro whetū he whakanui i te ahua o ngā mea o te rangi kia kitea ai mā te whakamahi i ngā kanohi.
Ngā momo karu tiro whetū
He maha ngā momo karu tiro whetū, tae atu ki ngā karu tiro whakaata me ngā karu tiro whakaata. Ko te karu tiro whakaata, e mōhiotia ana ko te karu tiro Keplerian, he mea tito mai i ngā karu tiro pūkohu e rua e whakanohoia ana ki ngā pito e rua o te ngongo. Ko ngā karu tiro pūkohu e tawhiti atu ana i te kanohi o te kaimātakitaki ka kiia ko te karu tiro whāinga, ko ngā karu tiro pūkohu e tata atu ana ki te kanohi ka kiia ko te karu tiro kanohi. Kia kitea ai te ahua o te mea, me nui te mata o te karu tiro whāinga. He uaua te hanga karu tiro whānui, nō reira kāore i te rahi te rahi o te karu tiro whakaata. Ko ngā karu tiro nunui he karu tiro whakaata. Ka whakamahia e ngā karu tiro whakaata ngā whakaata pūkohu hei whakaata whāinga.
E arotahi ana tēnei tuhinga ki te karu tiro whetū, ki te karu tiro Keplerian rānei.
Te mahi a ngā karu tiro whetū
E rua ngā karāhe pūkohu o te karu tiro whetū. Ko te karāhe pūkohu he tawhiti atu i te kanohi o te kaimātakitaki ka kiia ko te karāhe whāinga, ko te karāhe pūkohu e tata atu ana ki te kanohi o te kaimātakitaki ka kiia ko te karāhe kanohi, ko te karāhe kanohi rānei. He tino tawhiti te tūnga o te mea, ā, he iti noa iho te koki i waenganui i te mea me te karāhe whāinga.
Nō reira, ko te mahi a te karu arotahi he whakatata i te ahua ki te karu kanohi kia nui ake ai te koki. Ko te mahi a te karu kanohi he whakanui ake i te koki kia nui ake ai te rahi o te ahua i hangaia ki te retina.
He tino tawhiti te tawhiti i waenga i ngā mea me te karāhe arotahi, ā, e kiia ana he mutunga kore. E ai ki te tuhinga mō te karāhe arotahi, ki te tino tawhiti, ki te mutunga kore rānei te tawhiti o te mea, kei te pūwāhi arotahi tonu te ahua o te karāhe arotahi. He tūturu te ahua, he huripokitia, he iti iho. Nā te mea kei te pūwāhi arotahi o te karāhe arotahi te ahua, ko te tawhiti i waenga i te ahua me te karāhe arotahi (di ob ) he rite ki te roa arotahi o te karāhe arotahi (F ob ).
He tūturu te ahua i hangaia e te karāhe arotahi, nō reira ka kiia he mea e te karāhe kanohi. Mena he iti rawa te wāhi e arohia ana ngā kanohi (he tawhiti te arotahi o te kanohi), ka mutu te āhua o te ahua i hangaia e te karāhe kanohi. E ai ki te kaupapa o te karāhe pūkohu,
kia mutunga kore ai te ahua i hangaia e te karu kanohi, ko te ahua tūturu i hangaia e te karu arotahi, ā, e kiia ana he mea e te karu kanohi,
Haunga te noho ki te pūwāhi arotahi o te arotahi arotahi, me noho hoki ki te pūwāhi arotahi o te arotahi kanohi. Nō reira, ka taea te whakatau ko ngā pūwāhi arotahi o te arotahi arotahi me te pūwāhi arotahi tuatahi o te arotahi kanohi ka rite tetahi ki tetahi, e whakaaturia ana i te pikitia. Ina te roa arotahi o te arotahi o te arotahi kanohi (fok) he ōrite ki te tawhiti o te ahua tūturu mai i te karu tirohanga (dook), ko te ahua whakamutunga i hangaia e te karu kanohi he mariko, he huripokitia, he whakanuia, ā, he
mutunga kore. Ehara i te mea ko te tawhiti mutunga kore o te ahua he mutunga kore te rahi o te ahua.
I runga i te whakaahua me te whakamārama i runga ake nei, ka taea te whakatau ko
Ko te tawhiti i waenganui i te karāhe arotahi me te karāhe kanohi o te karu tiro whetū = te roa o te karu tiro whetū = te roa arotahi o te karāhe arotahi (f ob ) + te roa arotahi o te karu tiro (f ok ).
Mena he wāhi tino pai te urunga o te kanohi, ko te ahua i hangaia e te karu kanohi kei te pūwāhi tata o te kanohi noa, kei te 25 cm rānei ki mua i te karu kanohi,
ko te tawhiti o te ahua he iti ake i te roa arotahi o te karu kanohi (f o ). Ko te tawhiti o te ahua i hangaia e te karu kanohi he iti ake i te roa arotahi o te karu kanohi (f ok ) kia mariko ai te ahua, kia hurihia hoki. Ka taea te ako i tētahi whakamārama katoa mō te kaupapa o ngā whārite o te karu whetū.
Te whakanui katoa o ngā karu tiro whetū
He nui ake te rahi o te ahua o tētahi mea e kitea ana mā te karu tirohanga whetū ina tirohia e ngā kanohi he iti rawa te wāhi noho, he nui rawa rānei te wāhi noho? Ko tēhea te mea hei whakamahi mā te karu tirohanga whāinga me te karu tirohanga kanohi, he karu tirohanga pūkohu he nui te roa arotahi, he karu tirohanga pūkohu rānei he iti te roa arotahi? Ka taea te whakautu i ēnei pātai i muri i tō ako i te whārite o te karu tirohanga whetū.
