He aha nā asteroids a me ka mea ua ike no ia?

He aha nā asteroids? Ka mua mea aʻu i makemake makemake, e olelo aku i ka ai-kapaia pohaku paa kino e holo i loko o ka poe orbits elliptically hoʻokino e like me ka Honua ma ka. Eia naʻe, wa asteroids i he oi aku ka li nui ma mua, ma ka mea, o ka hoku a lakou iho. Lākou anawaena mea conventionally e pili ana i ke kēia papa koa: mai i kekahi mau na umi o mika i na tausani o ka kilomika.

O ka naau i ka asteroids, a me ka poʻe hiki ole ke kōkua manaʻo e pili ana i kahi a pau i kēia hele mai i ka makahiki, mea ia 'o ia hoʻi. He translates like "hoku-me", a hoʻolauna pū aku i ka XVIII kenekulia astronomer nona ka inoaʻo William Herschel.

Comets a me asteroids i e hiki i wahi malamalama kumu o ka manaʻo, oi a emi huali ia. ʻOiai i loko o ka hiki huaheluʻikepili ka lani kino mai i pāhawewe hou - noonoo wale ka Map e kau mai maluna o lakou. It E e kaulana i comets oko mai asteroids. Mua - ka mea, o ko lakou poe okoa helehelena. Comet wale recognizable ma ka glowing nucleus a me ka huelo e hele mai ia.

Ka hapa nui o na asteroids, a i ike i ka astronomers i keia la, kolo ana ma waena o nā orbits o Dia, a Mars ma ke kaawale ana o kahi o 2.2-3.2 a. E, ( 'o ia hoʻi, Astronomical Unit) , mai ka lā. I ka lā, ua 'ike akula' epekema ma kahi o 20 tausani asteroids. Kakau o ia wale nō, he kanalima pakeneka. He aha nā asteroids i kakau? Kēia lani kino, a ua häʻawi mai i ka helu, a me kekahi manawa, a hiki i ko lakou mau inoa. e hoʻololi i kā lākou mau orbits me kiʻekiʻe loa pololei. It E e kaulana ia mau ano lani kahi mea i hookuu i ka inoa i ka mea, ua appropriated lākou discoverers. Nā inoa o nā asteroids lawe, IeAUPIIe, IAa IO mai Greek pili kūpono loa.

Nohona ma, mai ka luna ka ho'ākāka 'ana, ka mea, ua ike i na asteroids. Akā, he aha hou aʻe mea typical no ia?

E like me ka hopena o kaʻikepili no nā loina o ka lani kahi ma ka telescope ka mea i ike i ka hana hoihoi mea. I ka'ōlinolino o ka helu nui o asteroids hiki ke hoʻololi, a me ka loa pōkole manawa - keia e kaili ia mau lā paha i kekahi mau hola. ʻepekema, Ua lōʻihi wänana i ia mau loli ma ka glare o na asteroids i pili me kā lākou kuapo. It E e kaulana ia mea, e kena aku e - ka loa mua - kā lākou ole kinona. A me ka mea mua kiʻi ma i kēia mau ano lani kahi (e ia i nā kiʻi me ke kōkua i pio spacecraft), hookupaa iho la ia i kēia kumumanaʻo, akā, hoike i ka hahai: ka ili o asteroids loa eli ia a hohonu craters a me craters o kekahi nui like 'ole.

Ka nui loa asteroid loaa i loko o ko makou poe lń, koke noʻonoʻo i ka lani kino Ceres, i mea e pili ana i ka nui o ka 975 m 909 ei. Akā, mai ka 2006 ka mea, ua loaa i kaʻokoʻa aʻe. A lilo iho la i kapa me he dwarf Honua. A me ka mea'ē aʻeʻelua nui asteroid (ma lalo o ka inoa o Pallas, a Vesta) i ke anawaena o ka 500 kilomika! Mākou E hoi e hoailona oukou i kekahi hana hoihoi mea. Ka mea i ka West - ka wale asteroid e maoli ike ia e ka maka kapa ole.
