Cloud Oort
|
The Nemesis Affair NEMESIS is the name given by scientists to a (theoretical) small companion star to our sun. Every 26 million years, Nemesis's orbit brings it close enough to the sun to bombard our solar system with billions of comets. While most of the comets will float harmlessly beyond the outer planets, some passing through the sun's Oort Cloud will be deflected by its gravitational force toward Earth. Such a large-body impact, the Nemesis theory holds, was responsible for the mass extinction that led to the demise of the dinosaurs. The next impact, millions of years from now, might very well extinguish humanity.In this lively, fascinating, cloud oort and often disturbing book, updated cloud oort and revised with the latest scientific evidence on terrestrial impacts, David M. Raup re-explores the controversies of the Nemesis theory from the trenches of the scientific community, cloud oort and investigates the issues both scientific cloud oort and philosophical of mass extinction.

.. The only prominent families are: Eos asteroids have a mean orbital radius between 2.99 AU and 3.24 AU, an eccentricity between 0.01 and 0.13, and an inclination less than 3°. They were first recognised by Kiyotsugu Hirayama in 1918 and are often called Hirayama families in his honour. Minor planet is the official term of asteroids after the first member of that group to be discovered (generally the largest). The largest minor planets are divided into groups and families based on their orbital characteristics. Named after 221 Eos, ~480 members known. Themis asteroids have a mean orbital radius between 2.99 AU and 3.03 AU, an eccentricity between 0.09 and 0.22, and an inclination between 8° and 12°. They are objects in the solar system that orbit the Sun like planets, but which are smaller than planets and not counted among them. If a minor planet produces coma it is called a comet (though conversely not all comets are classified as minor planets). It is customary to name a group of asteroids after the first member of that group to be discovered (generally the largest). The largest minor planets are divided into groups and families based on their orbital characteristics. Named after 24 Themis, ~535 members ...
