8. juulil kaob \u00f6\u00f6taevast \u00fcsna heleda t\u00e4he, mida tuntakse nimega Delta Ophiuchi, siluett. Siiski pole p\u00f5hjust muretseda. Palja silmaga n\u00e4htavat t\u00e4hte ei s\u00f6\u00f6 ega sure \u2013 seda varjab lihtsalt kiiresti liikuv asteroid.<\/p>\n<\/div>\n

M\u00f5ne sekundi jooksul asub see v\u00e4ike kivikamakas, mida tuntakse nimetusega (472) Roma, just \u00f5iges kohas ja \u00f5igel ajal, et varjata Maale j\u00f5udvat t\u00e4hevalgust. See on haruldane s\u00fcndmus \u2013 ainus kord sel sajandil, mil on v\u00f5imalik n\u00e4ha, kuidas asteroid varjab t\u00e4he ilma binokli v\u00f5i teleskoobi abita.<\/p>\n

K\u00f5ik teavad, mis on p\u00e4ikesevarjutus \u2013 see on n\u00e4htus, mille k\u00e4igus Kuu liigub P\u00e4ikese eest l\u00e4bi ja taevas muutub m\u00f5neks minutiks pimedaks. Kuigi Kuu on 400 korda v\u00e4iksem kui P\u00e4ike, on ta ka 400 korda l\u00e4hemal, mist\u00f5ttu suudab ta katta meie l\u00e4hima t\u00e4he kogu ketta.<\/p>\n

Sama v\u00f5ib juhtuda ka kaugemate t\u00e4htedega. 50 km laiune asteroid, nagu n\u00e4iteks Roma, v\u00f5ib l\u00fchiajaliselt varjata sellist hiiglaslikku t\u00e4hte nagu Delta Ophiuchi, sest see kosmosekivi asub meist palju l\u00e4hemal. Sellised s\u00fcndmused on olulised, sest need v\u00f5imaldavad astronoomidel v\u00e4lja arvutada asteroidide suuruse ja kuju \u2013 sealhulgas ka nende, mis v\u00f5ivad \u00fchel p\u00e4eval Maaga kokku p\u00f5rkuda.<\/p>\n

T\u00e4he kadumist saab n\u00e4ha vaid umbes 50 km laiuses v\u00f6\u00f6ndis, mis \u00fchendab Stockholmi, Kopenhaagenit, Bremeni, Nantes\u2019i, Bilbaot ja Kanaari saari. See toimub umbes kell 23:57 Kesk-Euroopa suveaja j\u00e4rgi, kuigi t\u00e4pne aeg varieerub piirkonniti.<\/p>\n
