NASA's Near-Earth Object Program Office . ... This paper briefly presents the history, interactions and current activities of NASA's Near-Earth Object Program Office. The Program Office utilizes near-Earth object (NEO) astrometric data from the international community, received from the Minor Planet Center, to refine orbits and provide predictions for coming Earth close approaches. ... Recent studies of some of the issues surrounding the deflection of an Earth threatening NEO are also described. ...

... The force F of gravity between two objects of mass m and M, whose centres are a distance r apart, is given by Newton's famous equation: [pic], where G = 6.67(10-11 N m2 kg-2, and F is measured in Newtons. So, the force in orbit Fo is weaker than the force on the Earth's surface F0 by the ratio: [pic] where the radius of the Earth is 6,400 km, and the orbit is 1000 km above the Earth's surface. ... Energy Considerations Another way to see all this is to consider the energy of an object in orbit. ...

... The ancient chronical said about the colour rings around the Sun and the Moon, about three suns in the sky, light columns, bright lightning, different "comets" rushing to the Earth, moving among the stars or round the Earth with the sky. All these occurrences may be divided into three categories: one that occur in the near or far space, processes going on in the Earth atmosphere under the influence of cosmic factors and at last the occurrences connected with the Earth atmosphere. ...
