Note added 3 June 2003 to . ... Furthermore, (iii) its orbital plane gave the satellite at apogee a velocity tangential to the ecliptic, helping it stay in the plasma sheet, rather than cut across it. ... Figure #1 Point A in this drawing is perigee (just above Kourou), B is apogee , the solid line perpendicular to the Earth axis is a cut through the equatorial plane, and its continuation parallel to the ecliptic represents a cut through the plasma sheet (not to scale). ...

... About ATNF overview . ... Australia Telescope Steering Committee . ... Parkes radio telescope . ... A Search for Distant Satellites of Neptune . ... Previous surveys for distant satellites of Neptune have had relatively bright magnitude limits ( ) and would have missed satellites with magnitudes and colours similar to the 2 recently discovered Uranian satellites ( and ). ... This search is up to magnitudes deeper than the previous wide field search for distant satellites by the UK Schmidt Telescope....

The wall around the crater is 5 kilometers high, and that central peak rises 6 kilometers above the surface (many impact craters have a large central peak which is caused by a pressure rebound from the impact). ... 2008 Phil Plait. ...

The AFOE is capable of obtaining radial velocity precision better than 10 m s-1 on relatively bright stars, and has produced data confirming the low mass companions to 51 Peg, Boo, and And. ...

Different types of satellite orbits have different uses: while the synchronous orbit is best for communication satellites, Lagrangian point orbits help monitor the solar wind before it reaches Earth. A low altitude polar orbit is widely used for monitoring the Earth because each day, as the Earth rotates below it, the entire surface is covered. ... A different choice was made for MAGSAT, orbited 1979-80 to survey the Earth's own magnetic field near its surface. ...

... 1Wills Accurate measurements of relative flux density have been made between frequencies of 468 and 5009 MHz for 300 radio sources selected from Parkes catalogue. ... Excluding the incertainties in scaling these flux densities to an absolute system, rms errors vary from 0.24 Jy and 2.4 % at 635 MHz to 1.8 % at 2700 MHz; uncertainties in "absolute" scaling are thought to be about 45 %. ... Some sources whose spectra may be useful for flux density calibration are noted. ...

... Equations are obtained for the plane relative motion of the system on the taut thread (on the assumption that the centre of mass of the system moves along the Keplerian elliptic orbit). ... The torques of gravitational forces, aerodynamic pressure, aerodynamic friction and the aerogradient effect are taken into account. ... First, the problem is investigated in case of taut thread and Keplerian elliptic motion of the centre of mass. ... In a general case the free motion is bound to become connected....
