ʻIke ʻia ka honua nunui e kaapuni ʻana ma kahi o ka hōkū dwarf
Hiki i kēia mea i loaʻa ke kumu i ka loiloi hou ʻana i ka honua.
Ua ʻike nā kilo kilo a Honua e like me ka hoʻopuni ʻana ʻo Jupiter ma kahi o kahi liʻiliʻi Hōkū ʻulaʻula. ʻO kēia mau hōkū ʻulaʻula liʻiliʻi i waena o nā mea maʻamau i ke ao holoʻokoʻa, ʻoiai ke hōʻike nei lākou ma mua o 70% o nā hōkū i ko mākou cosmos. ʻO ka hōkū ʻulaʻula ʻike ʻia lākou e ke anuanu a me ka liʻiliʻi; pili like lākou i ka ʻelima o kā mākou ʻōnaehana lā, nunui lākou e like me ka lā, akā 50 mau manawa ʻoi aku ka pouli. ʻOiai he mau hōkū ʻulaʻula i ka nui, ua manaʻo ʻia he 10% wale nō o nā exoplanets e hele mai e hoʻopuni i kēia mau hōkū.
I ke kaʻina hana noiʻi, ke kālailai nei nā kilo hōkū i ka hōkū dwarf ʻulaʻula kokoke i kapa ʻia GJ 3512. Ua ʻike lākou i kēia hōkū, aia ma kahi o 31 mau makahiki māmā mai ko mākou Honua a ʻo kona nui he ʻewalu mau manawa ka liʻiliʻi ma mua o ka lā a ʻoiai he ʻōlinolino nui kona, ʻaʻole like ia me ka lā e like me ka nui.
Este Honuakāheaʻia GJ 3512b Ua lilo ia i pilikua kinoea i ʻike maka ʻole ʻia i ka wā o kahi hoʻokolokolo e hana ʻia e nā mea nānā hoku o Calar Alto, Montsec a me Sierra Nevada ma Sepania me ka Las Cumbres Observatory ma Kaleponi.
Ua ʻoi aku ka nui o GJ 3512b ma mua o ka mea i hoʻoholo ʻia i ka loaʻa mua. ʻO ka hōkū GJ 3512 he 250 wale nō ka nui ma mua o ka honua GJ 3512b.
Nā ʻike hou a me nā kuhiakau
ʻ suggestedlelo nā kānaka ʻepekema hiki paha i kahi planet kolosal nui ke hoʻohālikelike i ka hōkū GJ 3512b; no ka mea ʻo ka orbit elongated o ka hōkū me ka honua nunui ʻike ʻia e hōʻike ana i kēia honua i kekahi manawa i kona ola ʻana, ua komo i loko o kahi puʻupuʻu puʻupuʻu me kekahi honua nui i hoʻokuʻu ʻia mai ka ʻōnaehana interstellar.
I kēia manawa, hoʻomau ka poʻe noiʻi e nānā a hoʻopaʻa i kēia honua i ʻike ʻia a hoʻolālā e hoʻomau i ka hoʻopili ʻana ma kahi o 300 mau hōkū dwarf ʻulaʻula e hoʻomau i ka loaʻa ʻana o nā exoplanets.
Hoʻopili nā ʻepekema i ka hoʻokumu ʻana o kahi ʻōnaehana e hōʻiliʻili i nā ʻōpala ākea
