Yhdessä ne eivät ole yhtä kirkkaita kuin aiemmin, eikä niistä tässä tapauksessa näytä tulevan yhtä kirkasta pyrstöä kuin olisi tullut yhdestä isosta komeettaytimestä.</p> <p>Komeettojen hajoaminen ei ole mitenkään poikkeuksellista. Se on jopa tavallista. Eräs näyttävimmistä viime aikojen tapauksista oli komeetta <em><a href="https://web.archive.org/web/20200511053853/https://en.wikipedia.org/wiki/73P/Schwassmann–Wachmann" class="ydd-article-link ydd-article-link--standard">73P/Schwassmann-Wachmannin</a></em> rikkoontuminen neljään ryppääseen pienempiä osia vuonna 2006. Tästä on kuva jutun otsikkona.</p> <p>Komeetan nimeä ei ole muuten temmattu Korkeajännityksestä, vaan tyypilliseen tapaan nimessä on löytäjän nimi tai kahden ensimmäisen löytäjän nimet sekä alussa <a href="https://web.archive.org/web/20200511053853/https://www.iau.org/public/themes/naming/#comets" class="ydd-article-link ydd-article-link--standard">Kansainvälisen astronomisen unionin</a> numerokoodi. Tässä tapauksessa kyseessä on periodinen (säännöllisesti uudelleen Auringon luokse tuleva) komeetta 73 ja Hampurin observatorion tähtitieteilijät Friedrich Schwassmann ja Arno Wachmann.</p> <p>Kun komeetta löydetään taivaalta ensimmäisen kerran, saa se nimeensä vuosiluvun ja järjestyskoodin. Kun se havaitaan useamman kerran, annetaan sille oma numero.</p> <h3>1. Komeetat hajoavat kuin lumiukot kevätsäillä</h3> <p>Komeettoja kutsutaan usein "likaisiksi lumipalloiksi", koska niissä on paljon kiviainesta ja jäätä, ja aivan kuten lumipallot, ovat ne kovin erilaisia kovuudeltaan. Osa komeetoista on selvästi tiukempaa tavaraa, osa taas ei ole. Toisissa on enemmän jäätä ja lunta, toisissa enemmän soraa sekä kiveä.</p> <p>Lisäksi monet komeettojen ytimistä näyttävät koostuvan useammista osista. Kaksiosaiset "lumiukot" ovat todennäköisesti tavallisia, eli kaksi ydintä on lyöttäytynyt joskus aikanaan yhteen.

Komeetat tuhoutuvat pikkukiviksi Auringon lähellä</h3> <p>Hyvin läheltä Aurinkoa kulkevia komeettoja kutsutaan auringonhipojiksi, ja monesti niiden kohtalo on karu: ne musertuvat ihan palasiksi. </p> <p>Tunnetuin viime aikojen tapaus on <em><a href="https://web.archive.org/web/20200511053853/https://en.wikipedia.org/wiki/Comet_ISON" class="ydd-article-link ydd-article-link--standard">komeetta ISON</a></em>, eli <em>C/2012 S1</em>, josta odotettiin loppuvuodesta 2013 todella kirkasta komeettaa taivaalle. Se lähestyi Aurinkoa ja sen kirkkaus kasvoi voimakkaasti, ja se olisi tullut Auringon ohitettuaan hyvin näkyviin maapallolta.</p> <p>ISON kävi niin lähellä Aurinkoa, että se näkyi hyvin Aurinkoa tutkivien satelliittien kuvakentissä. Lähimmillään se oli vain noin 1,2 miljoonan kilometrin päässä Auringon pinnasta, jolloin sen nopeus radallaan oli huimat 1,35 miljoonaa kilometriä tunnissa – tosin vain radan kaikkein Aurinkoa lähimmässä pisteessä. Hyvin lähellä paitsi vuorovesivoimat ovat suuria, niin myös Aurinko porottaa kuumasti. Komeetalle oli ennättänyt tulemaan jo pitkä, komea pyrstö.</p> <p>Auringon lähiohituksen jälkeen komeetasta oli jäljellä vain pieni haamu. Ydin todennäköisesti oli alkanut jo hajota osiin, ja lähellä Aurinkoa kuumuus käytännössä höyrysti osista ainakin kaiken jään. Ilman höyrystyvää jäätä ei komeettaytimelle muodostunut enää pyrstöä, joten se saattoi olla enää vaatimaton kivikokkare tai monta pientä kokkaretta.</p> <p>Toisaalta kaksi vuotta aikaisemmin komeetta <em><a href="https://web.archive.org/web/20200511053853/https://en.wikipedia.org/wiki/C/2011_W3_(Lovejoy)" class="ydd-article-link ydd-article-link--standard">C/2011 W3 Lovejoy</a></em> oli kulkenut Auringon ohi jopa lähempää, ja se näkyi sen jälkeen komeasti taivaalla joulun 2011 tienoilla ihan paljain silmin.</p> <div itemprop="image" itemscope="" itemtype="https://schema.org/ImageObject" class="ydd-image ydd-image--inline"> <figure class="ydd-image__wrapper ydd-fluid-aspect-ratio-placeholder" data-aspect-ratio="2:3"> <a href="https://web.archive.org/web/20200511053853/https://images.cdn.yle.fi/image/upload/f_auto,fl_progressive/q_88/w_2571,h_3857,c_crop,x_133,y_0/w_1400,h_1400,c_fit/v1587049118/39-6651845e98722cdd2e0.jpg" class="colorbox" data-copyright="NASA" data-description="Komeetta Lovejoy kuvattuna Kansainväliseltä avaruusasemalta." data-public-id="39-6651845e98722cdd2e0" data-height="1400" data-width="933" rel="nofollow"><img alt="Komeetta Lovejoy kuvattuna avaruusasemalta." title="Komeetta Lovejoy kuvattuna Kansainväliseltä avaruusasemalta." src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" itemprop="image" content="https://images.cdn.yle.fi/image/upload/f_auto,fl_progressive/fl_keep_iptc/q_88/w_2571,h_3857,c_crop,x_133,y_0/w_700/v1587049118/39-6651845e98722cdd2e0.jpg" data-base-url="https://web.archive.org/web/20200511053853/https://images.cdn.yle.fi/image/upload/f_auto,fl_progressive/" data-public-id="39-6651845e98722cdd2e0" data-yle-id="39-6651845e98722cdd2e0" data-crop-coords="w_2571,h_3857,c_crop,x_133,y_0" data-image-width="2571" data-image-height="3857" data-image-version="1587049118" data-initial-width="" data-default-width="300" class="ydd-image__image lazyload" data-src="https://web.archive.org/web/20200511053853/https://images.cdn.yle.fi/image/upload/f_auto,fl_progressive/q_80/w_2571,h_3857,c_crop,x_133,y_0/w_300/v1587049118/39-6651845e98722cdd2e0.jpg"/> </a> <meta itemprop="url" content="https://web.archive.org/web/20200511053853/https://images.cdn.yle.fi/image/upload/f_auto,fl_progressive/fl_keep_iptc/q_88/w_2571,h_3857,c_crop,x_133,y_0/w_700/v1587049118/39-6651845e98722cdd2e0.jpg"/> <meta itemprop="width" content="700"/> <meta itemprop="height" content="1050"/> <noscript><img typeof="foaf:Image" src="https://web.archive.org/web/20200511053853im_/https://images.cdn.yle.fi/image/upload/f_auto,fl_progressive/q_80/w_2571,h_3857,c_crop,x_133,y_0/w_300/v1587049118/39-6651845e98722cdd2e0.jpg" alt="Komeetta Lovejoy kuvattuna avaruusasemalta." title="Komeetta Lovejoy kuvattuna Kansainväliseltä avaruusasemalta."/></noscript> </figure> <div class="ydd-image__captions"> <em class="ydd-image__caption" itemprop="description">Komeetta Lovejoy kuvattuna Kansainväliseltä avaruusasemalta.</em> <span class="ydd-image__description">Komeetta Lovejoy kuvattuna avaruusasemalta.</span> <span class="ydd-image__copyright" itemprop="copyrightHolder">Kuva: NASA</span> <span class="ydd-image__tags ydd-is-hidden" itemprop="keywords">auringonhipojakomeetta,komeetat,lovejoy-komeetta</span> </div> </div> <h3>3. Muut planeetat repivät komeettoja palasiksi</h3> <p>Auringon lisäksi myös planeetat, etenkin jättiläisplaneetta Jupiter saattaa murentaa komeettoja.

Tuloksena oli helminauhamainen näky, kun erikokoiset komeetan palaset olivat alkuperäisen komeetan radalla peräkkäin. Ne olivat kuin 21 pientä pyrstötähteä jonossa.</p> <p>Koska rata kulki jo alun perin läheltä Jupiteria, ja Jupiter väänsi sitä hieman itseensä päin, vei uusi rata komeetan palaset suoralle törmäyskurssille Jupiterin kanssa. Osat iskeytyivät planeettaan heinäkuussa 1994, ja tätä tapahtumaa pystyttiin seuraamaan Maan päältä kaukoputkin. Lisäksi kohti Jupiteria matkannut <em>Galileo-luotain</em> oli aitiopaikalla todistamassa tätä ensimmäistä ihmisten näkemää ison kappaleen törmäystä toiseen taivaankappaleeseen. </p> <div itemprop="image" itemscope="" itemtype="https://schema.org/ImageObject" class="ydd-image ydd-image--inline"> <figure class="ydd-image__wrapper ydd-fluid-aspect-ratio-placeholder" data-aspect-ratio="5:2"> <a href="https://web.archive.org/web/20200511053853/https://images.cdn.yle.fi/image/upload/f_auto,fl_progressive/q_88/w_2092,h_837,c_crop,x_425,y_0/w_1400,h_839,c_fit/v1587049790/39-6652385e9874d695504.jpg" class="colorbox" data-copyright="NASA, ESA, and H.

Itse asiassa useampikin, mutta tämä <em>C/2020 F8 SWAN</em> saattaa olla paljain silmin näkyvissä toukokuun puolivälissä. </p> <p>Komeetta löytyi 25. maaliskuuta Aurinkoa tutkivan SOHO-satelliitin SWAN-mittalaitteen kuvista, ja se on tulossa parhaillaan kohti Aurinkokunnan sisäosia. Parhaiten se on näkyvissä toukokuun 13, kun se on lähimpänä Maata. Tällöin se on 13. toukokuuta, jolloin meidän välinen matkamme on ainoastaan 83,2 miljoonaa kilometriä.</p> <p>Aurinkoa lähinnä SWAN on toukokuun 27. päivänä. Se kiertää Aurinkoa hyvin soikealla radalla kerran noin 10 000 vuodessa. Koska komeetta on suurimman osan ajastaan kaukana avaruuden kylmyydessä, on sen pinnalla mahdollisesti paljon suhteellisen tuoretta ainetta. Tiedetään, että tällainen jääaines saa usein lämmetessään aikaan paljon purskeita ja muodostaa komean pyrstön. </p> <p>Ellei komeetta hajoa kappaleiksi tai tule jotain muuta yllättävää, niin sen kirkkaus saattaa olla juuri ja juuri sopiva ilman kiikariakin näkemiseen. SWAN on parhaiten näkyvissä eteläisellä pallonpuolella, mutta toukokuun lopussa sen rata kääntyy myös pohjoisen puolelle. Suomessa yöt ovat kuitenkin niin valoisia, ettei sen näkemisestä ole juuri toivoa, vaikka komeetasta tulisi kovastikin kirkas.</p> <p>Komeetalla on yllättävä suomalaisyhteys: sen löytänyt SWAN-mittalaite on ranskalais-suomalaista yhteistyötä. Ja hyvää sellaista, koska laite on toiminut jo vuodesta 1995 alkaen ja pelittää siis edelleen erinomaisest</p> <aside class="ydd-article__related clearfix"> <h4>Aiheeseen liittyvät linkit</h4> <ul
