Bulge astronomy definition
WebThe Milky Way Galaxy’s structure is fairly typical of a large spiral system. (Spiral galaxies and other types of galaxies are described in the article galaxy.)This structure can be viewed as consisting of six separate parts: (1) a nucleus, (2) a central bulge, (3) a disk (both a thin and a thick disk), (4) spiral arms, (5) a spherical component, and (6) a massive halo. WebTides. The Earth and the Moon directly influence each other, so it is best to think of these two objects as part of one larger system, rather than two separate, individual objects. Compared to the Earth, the Moon is …
