MESSENGER at Mercury . ... Credit Copyright: NASA / JHU APL / CIW Explanation: On March 17, the MESSENGER spacecraft became the first to orbit Mercury, the solar system's innermost planet . This is its first processed color image since entering Mercury orbit. ... But in this view its terrain shows light blue and brown areas near craters and long bright rays of material streaking the surface. The prominent bright ray crater Debussy at the upper right is 80 kilometers (50 miles) in diameter. ...

We have used spectra taken between 1992 and 1997 to derive the spectroscopic orbit of the eclipsing double-lined spectroscopic binary HD 197770. This binary has a period of 99.69 +/- 0.02 days and K amplitudes of 31.2 +/- 0.8 and 47.1 +/- 0.4 km s^-1 for components A and B, respectively. ... These images show two apparent shells centered on HD 197770, a bright 60 ЮМm shell with a 28' diameter and a larger (0.8d diameter) bubble-like feature. ... ADS ] .

... SUN MOON MERCURY VENUS MARS, JUPITER SATURN . ... An artificial comet holds secrets to Earths life . ... If a brown dwarf orbited the Sun at the same distance as Jupiter, would life have evolved on Earth? ... NASA/JPL-Caltech Computer simulations suggest that if a more massive object, like a brown dwarf (which contains the mass of dozens of Jupiters), orbited the Sun instead of Jupiter, it would have been harder for Earth and the other terrestrial planets (Mars, Venus, and Mercury) to have formed. ...

3) Planets and Brown Dwarfs . ... By its nature, this method is most sensitive to massive planets orbiting close to their stars. ... That means that some of the more massive extrasolar planets could actually be brown dwarfs (although the statistics of the finds suggest that most of them are not). ... Another possible difference between brown dwarfs and massive planets is how they are born. ... They would base the fundamental definition on the mode of formation: a planet is built from planetesimals. ...

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. ...
