Suppose we have 3 point-like masses (m 1 , m 2 , m 3 ) orbiting under their mutual attraction. The three form a triangle ABC with sides masses (R 1 , R 2 , R 3 ) where R 1 is the side across from m 1 , R 2 is across from m 2 and R 3 is across from m 3 (Figure 1). ... If we denoted the total mass by M . ...

Circling around magnetic field lines. ... The ring current . Because positive ions and negative electrons drift in opposite directions (see drawing), that motion will create an electric current that circulates clockwise around the Earth when viewed from north. ... How then can the radiation belt and ring current arise? ... Electric fields are able to push trapped particles earthward, and unlike the purely magnetic motion described earlier, an electric field can also energize them. ...

The Extended Soft Approximation for Spherical Particles A.Y. Perelman St.Petersburg State Forest Technical Academy and N.V. Voshchinnikov Astronomy Department and Sobolev Astronomical Institute, St.Petersburg University Abstract The soft approximation (SA) gives the possibility to obtain the different optical characteristics of particles from the common point of view [1]. As for the Mie theory, they are expressed in terms of the scattering coefficients $a_n$ and $b_n$. ...

... 8, ``Celestial Mechanics'', 2002 Estimation of masses of some minor planets from observations of perturbed bodies O. M. Kochetova Institute of Applied Astronomy, St. Petersburg, Russia The most straightforward method of mass determination of minor planets is the dynamical one which uses the gravitational perturbations produced by minor planet in the motion of other bodies. ... The values of the masses of minor planets (15), (29) and (65) appear to be rather close in both papers. ...

... Almost all DSOs require a telescope to see in any detail at all, though some can be detected with just binoculars, and a few can be barely seen with the unaided eye. ... DEGREE: Distances on the sky (sometimes called the celestial sphere) are measured in angular degrees rather than inches or feet. ... The magnification is the focal length of the telescope divided by the focal length of the eyepiece. ... Short focal length eyepieces are also termed high power, long focal length are low power. ...
