Mars at Western Quadrature

orbital-positions   Saturday June 6th the position of the planet Mars, with respect to the Earth and the Sun, places this planet at what is called western quadrature. At that orbital position Mars, and actually any outer planet at their respective quadrature, is at a 90 degree angle from the Earth as this graphic shows, and the banner graphic at the top of the page shows. Think last quarter Moon as that is a fair comparison of the relative positions of Earth, Sun, and Mars. At this position Mars leads the Sun across the sky from east to west as the Earth is rotating, meaning that Mars rises before the Sun.

   Saturday morning finds Mars, Saturn, Jupiter, Dwarf Planet Ceres, Neptune, and the waning gibbous Moon spread across the morning skies from southeast to southwest.
