The Perihelion Precession of Saturn, Planet X/Nemesis and MOND
We show that the anomalous retrograde perihelion precession of Saturn !& " , recently estimated by different teams of astronomers by processing ranging data from the Cassini spacecraft and amounting to some milliarcseconds per century, can be explained in terms of a localized, distant body X, not yet directly discovered in the remote periphery of the solar system. From the determination of its ...
متن کاملCassini magnetometer observations during Saturn orbit insertion.
Cassini's successful orbit insertion has provided the first examination of Saturn's magnetosphere in 23 years, revealing a dynamic plasma and magnetic environment on short and long time scales. There has been no noticeable change in the internal magnetic field, either in its strength or its near-alignment with the rotation axis. However, the external magnetic field is different compared with pa...
متن کاملStellar Occultation Saturn ' s Upper Observations of Atmosphere
We have analyzed three stellar occultation observations of Saturn's upper atmosphere during the years 1989 to 1995. These occultations probed the stratosphere at pressure levels about 0.5 to 20 pbars, intermediate to those probed by the Pioneer 11, Voyager I and II radio and ultraviolet occultations. The time span of the earlier occultations and the observation of a higher latitude occultation ...
متن کاملEarthshine Observations of an Inhabited Planet
Earthshine is sunlight that has been reflected from the dayside Earth onto the dark side of the Moon and back again to Earth. In recent times, there has been renewed interest in ground-based visible and near-infrared measurements of earthshine as a proxy for exoplanet observations. Observations of earthshine allow us to explore and characterize the globally integrated photometric, spectral and ...
متن کاملA Hot Saturn Planet Orbiting Hd 88133, from the N2k Consortium
The N2K consortium is carrying out a distributed observing campaign with the Keck, Magellan and Subaru telescopes, as well as the automatic photometric telescopes of Fairborn Observatory, in order to search for short-period gas giant planets around metal-rich stars. We have established a reservoir of more than 14,000 main sequence and subgiant stars, closer than 110 pc, brighter than Based on o...
