Mars Transits the Sun

saturn-mars-heliocentric_conjunction   Yes there will be a transit of the Sun by Mars, however you would have to be on the planet Saturn to see this transit as this graphic shows. This astronomical event is known as a heliocentric conjunction. It is determined by measuring, along the ecliptic, the angle between the Earth’s vernal equinox longitude, 0o, and a planet as would be seen if you were on the Sun.
   The Mars – Saturn heliocentric conjunction is on Saturday, 14 June, at 18 UT (1 pm CDT).
   While the short video below, taken by the Mars Curiosity Rover, is not a transit of the Sun by Mars it does show a transit of the Sun by Mercury as seen from the surface of Mars.

Caution: Objects viewed with an optical aid are further than they appear.
