N. Russell's recent book of the above title, the belief is expressed that the assumption of the sun having been originally one component of a binary star would help to resolve certain difficulties. To get rid of the other member an almost central collision with another star is invoked, but...
Origin of the Solar System Paragraph 1:The orderly nature of our solar system leads most astronomers to conclude that the planets formed at essentially the same time and from the same primordial (original) material as the Sun. This material formed a vast cloud of dust and gases called...

Solar system, assemblage consisting of the Sun and those bodies orbiting it: 8 planets with more than 400 known planetary satellites; many asteroids, some with their own satellites; comets and other icy bodies; and vast reaches of highly tenuous gas and
All this information is scrutinized in attempts to understand in detail the origin and evolution of the solar system—a goal toward which astronomers continue to make great strides. Composition of the solar system orbitsThe orbits of the planets and other bodies of the solar system.(more) ...
Defining planets: Characteristics and classifications in the solar system TheIAU definesa true planet as a body that circles the sun without being some other object's satellite; is large enough to be rounded by its own gravity (but not so big that it begins to undergo nuclear fusion, like ...
planets in a region of the solar system called the"Kuiper Belt" (PronouncedKYE-per Belt.)The Kuiper Belt extends out from the orbit of Neptune and is the realm of the most distant worlds known to exist in the solar system. It is very distant and its objects are likely icy and frozen....
