Authors: V.A. Marsakov , Yu.G. Shevelev , . Journal: 1988, Astron Zh. ... Absolute magnitudes, metallicities, effective temperatures, surface gravities, distances, and tangential velocities are calculated for 5498 F stars with homogeneous data on uvby photometry and proper motion, and placed within 80 pc from the Sun. Components of space velocities, eccentricities of galactic orbits, perigalactic and apogalactic distances, and maximal remotness from galactic plane are presented for 1787 stars. ...

... 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. ...
