Vopros nedeli. Mozhet li byt' Uran bol'she drugih planet Solnechnoi sistemy po vidimomu s Zemli diametru?
Otvety mozhno davat' v kommentariyah k dannoi stranichke.
Na dannoi nedele 20 oktyabrya Merkurii proidet v 2 gradusah yuzhnee Marsa. 21 oktyabrya nastupit maksimum deistviya meteornogo potoka Orionidy (ZHR= 15), a Luna (F= 0,01-) proidet bliz Spiki (pokrytie ne vidno iz-za blizosti k Solncu). 23 oktyabrya Luna (F= 0,04+) proidet bliz Merkuriya i Marsa, a pri faze 0,06+ dostignet apogeya svoei orbity na rasstoyanii 406445 km ot centra Zemli. 25 oktyabrya budet imet' mesto maksimal'naya severnaya libraciya Luny po shirote 6,7 gr., a takzhe proizoidet pokrytie Lunoi (F= 0,11+) Antaresa (pri vidimosti v Yuzhnoi Amerike i Antarktide). 26 oktyabrya Luna (F= 0,22+) proidet tochku maksimal'nogo skloneniya k yugu ot nebesnogo ekvatora.
Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy umen'shaetsya do 21 gradusa, a dolgota dnya na toi zhe shirote - do 9 chasov 40 minut. Vidimyi diametr Solnca uvelichivaetsya do 32,18 minut dugi, a dvizhetsya ono po sozvezdiyu Devy. Dannye o Solnce na tekushee vremya. Efemeridy Solnca na 2025 god
Luna. Estestvennyi sputnik Zemli vstupaet v fazu novoluniya 21 oktyabrya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Devy, Vesov, Skorpiona, Zmeenosca i Strel'ca, izmenyaya fazu ot 0,02- do 0,25+ i umen'shaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Devy. 21 oktyabrya pri faze 0,01- Luna proidet bliz Spiki (pokrytie ne vidno iz-za blizosti k Solncu). V etot den' Luna primet fazu novoluniya, a 22 oktyabrya lunnyi serp (F= 0,01+) pereidet v sozvezdie Vesov. Zdes' 23 oktyabrya pri faze 0,04+ molodoi mesyac proidet bliz Merkuriya i Marsa, a 24 oktyabrya pri faze 0,07+ dostignet sozvezdiya Skorpiona. Zdes' 25 oktyabrya proizoidet pokrytie Lunoi (F= 0,11+) Antaresa (pri vidimosti v Yuzhnoi Amerike i Antarktide). V etot zhe den' Luna (F= 0,11+) pereidet v sozvezdie Zmeenosca, a 26 oktyabrya pri faze 0,21+ - v sozvezdie Strel'ca. Fazy Luny na dannoe vremya i na budushee. Efemeridy Luny na 2025 god
Planety Solnechnoi sistemy. Merkurii i Mars nahodyatsya na vechernem nebe, Venera - na utrennem nebe, Yupiter i Uran nablyudayutsya noch'yu i utrom, a Saturn i Neptun vidny vecherom i noch'yu. Podrobnye efemeridy i karty dvizheniya bol'shih planet imeyutsya v Astronomicheskom kalendare na 2025 god i Astronomicheskih kalendaryah na blizhaishie gody.
