Mars – Jupiter at Heliocentric Conjunction

   Saturday March 3rd the outer planets Mars and Jupiter will be at a position along their respective orbits where they have the same heliocentric longitude of approximately 223o. However this does not mean that if you were to observe the two in the morning skies that they would be lined up. The are not. Rather, as this graphic shows, the two planets are lined up with each other and with the Sun, while the Earth is at a lower heliocentric longitude and not in the same line as the two planets.
