Καλημερα Φιλε! η αφροδιτη οπως πολυ σωστα λες μεχρι στιγμης δν εχει δορυφορο. αυτο που ειδες χθες,ηταν ενα αστερι,το οποιο ονομαζεται Nunki περισσοτερες πληροφοριες..απο starry night Nunki is a main sequence star, a star that burns hydrogen in its core. Every star spends most of its lifetime as a main sequence star. The properties of a main sequence star are determined completely by its mass, which can range from 1/20 the mass of the sun up to 50 times the mass of the sun. The more massive a star is, the hotter and brighter it will be, and the shorter it will live. A star's temperature also determines its colour. The hottest stars appear blue. Slightly cooler stars appear white or yellow, and the coolest stars appear orange or red. Our sun is slightly hotter and more massive than the average star on the main sequence.Nunki is both a variable star and one member of a multiple star system. It is possible that this star is an ‘eclipsing variable’. Eclipsing variables are members of a double star system which pass directly in front of their companion stars during their orbit. When this happens, light from the companion star is blocked, and the binary star appears fainter to observers on Earth. The most famous eclipsing binary is Algol, nicknamed ‘the Demon Star’ for its spooky changes in brightness. επισης απεχει 224.94 έτη φωτος απο εμας. ελπιζω να βοηθησα
