Fazy Luny na dannoe vremya i na budushee. Efemeridy Luny na 2025 god
Planety Solnechnoi sistemy. Merkurii, Venera, Saturn i Neptun nahodyatsya na utrennem nebe, a Mars, Yupiter i Uran - na vechernem nebe. Podrobnye efemeridy i karty dvizheniya bol'shih planet imeyutsya v Astronomicheskom kalendare na 2025 god i Astronomicheskih kalendaryah na blizhaishie gody.
Komety. Hvostataya strannica Tsuchinshan-ATLAS (C/2023 A3) pri bleske slabee 12m dvizhetsya po sozvezdiyu Lisichki. Karty putei komet i asteroidov na mesyac imeyutsya v Kalendare nablyudatelya na blizhaishie mesyacy, a na drugie periody - v Astronomicheskih kalendaryah na blizhaishie gody.
