Mars Opposes Neptune

mars-neptune-opp   And Uranus is at eastern quadrature. So what does that mean?
   Mars opposes Neptune in the sense that each planet is 180 degrees from the other and using their heliocentric coordinates Mars is at approximately 155o while Neptune is at approximately 334o. This is called heliocentric opposition as the two planets are on opposite sides of the Sun. When two planets are in heliocentric opposition and separetd by 180o one planet will be in the morning skies, Mars, while the other is in the evening skies, Neptune.

uranus-e.quad   The outer planet Uranus is at eastern quadrature today meaning that using the Earth, Sun, and Uranus the three form a right angle with Uranus 90o from the Earth and Sun. This places Uranus on the eastern side of the Earth as the Earth rotates. Whenever an outer planet is at or near eastern quadrature that planet or planets is to the east of the Sun and this places them in the evening or night skies.
