Tento t\u00fdden se na obloze odehraje jeden z nejzaj\u00edmav\u011bj\u0161\u00edch astronomick\u00fdch \u00fakaz\u016f roku 2026. M\u011bs\u00edc se dostane p\u0159\u00edmo p\u0159ed Venu\u0161i a na kr\u00e1tk\u00fd okam\u017eik ji zcela zakryje.

Venu\u0161e pat\u0159\u00ed po Slunci a M\u011bs\u00edci k nejjasn\u011bj\u0161\u00edm objekt\u016fm na obloze. Pr\u00e1v\u011b proto je jednou z m\u00e1la planet, kter\u00e9 lze za vhodn\u00fdch podm\u00ednek pozorovat i b\u011bhem dne. O to v\u00fdjime\u010dn\u011bj\u0161\u00ed je situace, kdy ji p\u0159ekryje M\u011bs\u00edc.<\/p>\n
\u201eNejzaj\u00edmav\u011bj\u0161\u00edm \u010dervnov\u00fdm \u00fakazem bude konjunkce dvou nejjasn\u011bj\u0161\u00edch planet, Venu\u0161e a\u00a0Jupiteru, kter\u00e1 nastane ve\u010der 9. 6., kdy ob\u011b planety budou ve vzd\u00e1lenosti zhruba 1,6\u00b0 \u2013 vejdou se tedy pohodln\u011b spole\u010dn\u011b do zorn\u00e9ho pole m\u00edrn\u011b zv\u011bt\u0161uj\u00edc\u00edho dalekohledu.

\u00dakaz samotn\u00fd nastane 17. \u010dervna. Nejl\u00e9pe pozorovateln\u00fd bude v \u010d\u00e1sti Severn\u00ed Ameriky, Karibiku a ji\u017en\u00ed Kanady, kde se odehraje je\u0161t\u011b p\u0159ed z\u00e1padem Slunce. V jin\u00fdch oblastech sv\u011bta bude viditeln\u00fd po setm\u011bn\u00ed.<\/p>\n
V dob\u011b z\u00e1krytu bude M\u011bs\u00edc osv\u011btlen pouze z 11 procent a bude m\u00edt podobu \u00fazk\u00e9ho dor\u016fstaj\u00edc\u00edho srpku. Samotn\u00e9 zakryt\u00ed Venu\u0161e potrv\u00e1 p\u0159ibli\u017en\u011b 29 sekund.

Zvl\u00e1\u0161tnost\u00ed cel\u00e9 ud\u00e1losti je i vzd\u00e1lenost Venu\u0161e od Slunce. Planeta se na obloze nikdy nevzd\u00e1l\u00ed v\u00edce ne\u017e o 47 stup\u0148\u016f. Tentokr\u00e1t se bude nach\u00e1zet asi 38 stup\u0148\u016f od Slunce, co\u017e vytv\u00e1\u0159\u00ed mimo\u0159\u00e1dn\u011b p\u0159\u00edzniv\u00e9 podm\u00ednky pro pozorov\u00e1n\u00ed.<\/p>\n
