PLANETARY INFORMATION

MERCURY
puts in its best evening appearance this year (look low in the west after sunset) for northern hemisphere observers during the first two weeks of May.
VENUS is visible in southeastern predawn skies but becomes lower and more difficult to see in predawn skies during May.
MARS
, moving into Cancer in May, is high in the early evening western sky but has faded significantly from its close approach in December, 2007. Its closest approach to Earth last year was on December 18, at which time it reached magnitude -1.6 and showed a disk almost 16 arcseconds across.
    Some relevant numbers for Mars:
             Date         Magnitude      Diameter ( " )      
           Dec. 20            -1.6              15.8                                                          
           Dec. 30            -1.5              15.4

Mars reaches aphelion at 249 million km (154,700,000 miles) from the Sun on May 12.                  
JUPITER is visible above the east-southeastern horizon in late evening (mid-May). The waning gibbous Moon passes near Jupiter on thye morning of May 24.
SATURN , in Leo near the star Regulus, is high in the SW sky after sunset and visible into the "wee hours." Saturn's rings are only tilted 8 or 9 degrees to us now; they will be edge-on (i.e., disappear from easy view!) during 2009.
