    Description

    Closest approach of Mars in 2016 occurs at 11:10 UT on May 22 when the planetocentric longitude of the Sun along the Martian ecliptic will be 161° with an apparent planetary disk diameter of 18.6" (74% of maximum possible) at a distance of 0.503 astronomical units (AU).

    This application monitors distance, angular size, light time and radial velocity of Mars with respect to Earth, also including a timer to and from closest approach. Size and magnitude are graphically compared with the 2003 opposition. Mars is displayed in the form of a rotateable 3D globe, as is Earth as seen from Mars. At opposition Earth faces Mars its entire night side, later turning crescent. A view of the elongations of both planet's from the sun is included as well.

    Also included, a visualization of Mars oppositions between 1950 and 2061.

    Provided countdown parameters:
    * Distance in AU, km and miles.
    * Angular size/magnitude
    * Light time
    * Radial velocity/orbital velocity
    * Time to closest approach
    * Zonal time at centered longitude
    * Martian seasonal longitude
