Very good astronomical encyclopedia

Very complete, it introduces the different notions of astronomy and about an accessible way physics. Trace the history of astronomical discovery. Addresses the solar system, the Milky Way and the rest of the known universe. He has illustrated each page, very pleasant to read. Giving examples in each described types of stars. It is technically complete even if the description of the solar system leaves something desired, especially in the sun, or more accurately would have had to refuse. And Pluto still considered a plantète but otherwise nothing else to say.

A Bought absolutely especially considering the price very low considering the quality :)
