Here we present the precalculated circumstances of the apparent encounters of the stars of the Tycho-2 Catalogue with the main satellites of Saturn (S1-S8) for the period from November 2004 to February 2010, and with the Galilean satellites of Jupiter for the period from November 2004 to October 2010. ...

IRREGULAR SATELLITES . ... Planetary satellites in the solar system are divided into two types: Regular satellites orbit in circular, equatorial orbits close to the planet. ... Irregular satellites orbit the planet much further out. ... Examples of irregular satellite orbits . ... Unlike the regular satellites which formed with the planet, irregulars originally formed in heliocentric space (eg the asteroid belt) and were later captured in a closed orbit around the planet. ...

... THE SIMPLEST MODEL. ... 13, Moscow 119992, Russia E-mail: san@sai.msu.ru Abstract: The analysis of the simplest model shows that an asteroid ­ rubble pile evolves, depending on the parameter V2d (where V is the average velocity of fragments and d is the average distance between fragments), either as a conglomerate of "independent mutually gravitating clusters" (when V2d < fm, where f is the gravitational constant and m is the average mass of a fragment) or as a "receding cluster" (when V2d > fm). ...

University Satellites and . Space Science Education . ... Two micro-spacecraft constellation with solar sails partially compensating the solar gravity allow their placement in the points along the Sun-Earth line behind the standard L1 point, i.e. further out from the Earth and closer to the Sun. The distances of the placement from the Earth and the base distances between such satellites depend on the ratios of their mass to the sail area. ...

... In this section, we develop a physical model of the secondary as a disk that is centrifugally supported in the radial direction and hydrostatically supported in the vertical direction. We assume that the disk is vertically isothermal and well mixed. ... where is the mean molecular mass of the gas, is the orbital period at the outer edge of the disk in years, and all of the mass of the secondary has been assumed to be concentrated near its center, so the Keplerian approximation is valid. ...
