Ka taea e maha e koe te whakarongo ki te pātai o nei o te aorangi mohiotia - te nui. Ao o te pūnaha solar ki te taimaha nui rawa - ko Hupita. Heoi, he iho ki aorangi maha nga kiato o reira. Hei tauira, te kiato o te whenua wa wha rite nui. Kua tukua tenei meka kaipūtaiao ki te faaoti e ngā Jupiter te nuinga o hau, e kore e whai te reira i te matua totoka. Jupiter hoki - ko te pūnaha solar ao nui i runga i te wahi pūtoro, a correspondingly, te nui o te mata, me te tahi atu āhuatanga e pā ana ki te rahi.
Ki te tahuri koe i roto i te whakataetae rahi o te ao, ka kitea i roto i te tahi atu pūnaha oranga, te-ka karanga kia "exoplanets" e e kia Jupiter - e kore ko te taata tei mau record tenei. Hei tauira, Tres-4 ao 1.4 wa nui atu i te pūnaha solar ao nui rawa. E ai ki tātaitanga, kia waiho he kapua o te hau i te iti rawa 15 ngā wā atu ki te roto tīmata tauhohenga karihi te kōtuitanga. Ko te aroaro o tenei tukanga ko whetu rerekē me ngā aorangi.
New tikanga o e kitea te tukua astrophysicists ki te whakatuwhera aorangi hou, me te hou katoa a tawhio noa te tahi atu whetu. Hua tutuki i roto i te tekau tau o mua kua whakaaturia e te pūnaha solar - noa tetahi o maha ngā pūnaha planetary. Kua hono ēnei rangahau tumanako o te taata roa-tu ki te kitea i ētahi atu ao e nohoia. kitea te exoplanet tuatahi i roto i 1992, a inaianei kua mohiotia hoki rau o exoplanets. exoplanets mohiotia te nuinga tēnei wā - ko te Rapa te rahi o Hupita nui ranei.
Aorangi āmio whetu tawhiti, he reira tino uaua ki te kitea, mai kore ratou e emit ratou ake marama, me te he tata rawa ki te whetu pokapū o te pūnaha e hāngai ana. Hei circumvent enei mau fifi, te whakamahi i kaipūtaiao he momo o tikanga e tukua ki a koe te hopu i te pānga mohio, e whakaatu ana i te aroaro o te aorangi huri noa te whetu ngā. Ko te tikanga nui rawa mō o te kimi aorangi āmio whetu tawhiti - tenei kitea puoro o te tere toropā. hāngai ana tēnei tikanga i runga i te meka e te ao he pānga meneti i runga i te kaupapa o nga whetu, e taea te mau i te te whakamahi i te inenga spectral rawa pau. Ko te nuinga pea, ki te kitea te aorangi tino nui e te hunga tata rawa ki te whetu tenei tikanga. Ko te tūpono i ka enei ao e nohoia, he iti. Ko te tūponotanga teitei o te imiraa i te ora extraterrestrial i runga i aorangi whenua-rite āmio i roto i te whitiki urutau ki te waihanga me te mau tonu te ora.
Kia aroha mai, te rapunga o aorangi he uaua faahiahia hoki whātata e hāngai ana whenua-. Ki tenei mutunga, mahere reira ki te whakarewa i whātata āmio, he ranea ki te mau exoplanets whenua-rite te tūtohutanga o nei.
Ko tētahi taua arorangi orbital "Kepler" taea kitea te rahi ekzoplanety rite ki te whenua, me te noa iti. Hei tauira, te ao Kepler-37b, kitea i roto i te pūnaha i roto i te kāhui whetū Lyra, he rite ki te marama te rahi. Ko reira tino kowaiwai o kōhauhau me te whero-wera ki pāmahana nui me te tūponotanga e ko te reira i te ora, e kore te nui. Ao o te pūnaha solar, rite i roto i te āhuatanga ki tenei exoplanet - Mercury. Ko te meka e te tino maro Kepler-37b - he meka faahiahia, me te akiaki.
