2980 Cameron
2980 Cameron, provisionally designated , is a main-belt asteroid discovered by prolific American astronomer Schelte Bus at Siding Spring Observatory Siding Spring Observatory near Coonabarabran, New South Wales, Australia, part of the Research School of Astronomy & Astrophysics (RSAA) at the Australian National University (ANU), incorporates the Anglo-Australian Telescope along with a coll ..., Australia, on March 2, 1981. It orbits the Sun every 4.11 years at a distance of 2.1–3.0 AU. The asteroid was named after astrophysicist and cosmogonist Alastair G. W. Cameron (1925–2005), who was associate director for theoretical astrophysics at the Center for Astrophysics Harvard & Smithsonian. He was an early advocate of the concepts of a turbulent accretion disk solar nebula, and of the origin of the Moon by a giant impact on the proto-Earth. He also studied the nucleosynthesis in stars and supernovae, and the cosmic abundances of nuclides. References Externa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alastair G
Alistair is a masculine given name. It is an Anglicised form of the Scottish Gaelic ''Alasdair''. The latter is most likely a Scottish Gaelic variant of the Norman French Alexandre or Latin Alexander, which was incorporated into English in the same form as Alexander. The deepest etymology is the Greek Ἀλέξανδρος (man-repeller): ἀλέξω (repel) + ἀνήρ (man), "the one who repels men", a warrior name. Another, not nearly so common, Anglicization of ''Alasdair'' is ''Allaster''. Hanks; Hardcastle; Hodges (2006) p. 399.

Proto-Earth
The history of Earth concerns the development of planet Earth from its formation to the present day. Nearly all branches of natural science have contributed to understanding of the main events of Earth's past, characterized by constant geological change and biological evolution. The geological time scale (GTS), as defined by international convention, depicts the large spans of time from the beginning of the Earth to the present, and its divisions chronicle some definitive events of Earth history. (In the graphic, Ma means "million years ago".) Earth formed around 4.54 billion years ago, approximately one-third the age of the universe, by accretion from the solar nebula. Volcanic outgassing probably created the primordial atmosphere and then the ocean, but the early atmosphere contained almost no oxygen. Much of the Earth was molten because of frequent collisions with other bodies which led to extreme volcanism. While the Earth was in its earliest stage (Early Earth), a g ...
