Neptune at Eastern Quadrature

1dec-neptune-east-quadrature   Sunday December 3rd the position of the planet Neptune with respect to the Earth and the Sun places this ringed planet at what is called Eastern Quadrature. Neptune is at a 90 degree angle from the Earth – think first quarter Moon as that is a fair comparison of the relative positions. At this position Neptune follows the Sun across the sky from east to west as the Earth is rotating, meaning that Neptune rises after the Sun and sets after the Sun.

   Where is Neptune now? The 8th planet from the Sun is currently within the constellation of Aquarius the Water Bearer and has recently completed its retrograde motion (November 22th).

   
   
   
   
   
   This is a 1 minute clip from a video I made showing Neptune and some of its moons as viewed from the Voyager 2 spacecraft. This clip is from a longer video of a tour of the solar system and was part of a live musical performance called “Orbit”. The performances were done at the Gottleib Planetarium in Science City at Union Station in Kansas City MO.

Mars at East Quadrature

orbital-positions   Tuesday September 13th the position of the planet Mars, with respect to the Earth and the Sun, places this planet at what is called eastern quadrature. At that orbital position Mars, and actually any outer planet, 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 first quarter Moon as that is a fair comparison of the relative positions of Earth, Sun, and Mars.
   At this position Mars follows the Sun across the sky from east to west as the Earth is rotating, meaning that Mars rises after the Sun and then sets after the Sun.

   This is a short video clip about Mars from a much longer video that I made as part of a live musical performance called “Orbit” at the Gottleib Planetarium in Kansas City Missouri a few years ago.

Uranus at Eastern Quadrature

   Thursday January 7th the position of the planet Uranus with respect to the Earth and the Sun places this ringed planet at what is called eastern quadrature. Uranus is at a 90 degree angle from the Earth as the banner graphic at the top of this page shows. Think first quarter Moon as that is a fair comparison of the relative positions. At this position Uranus follows the Sun across the sky from east to west as the Earth is rotating, meaning that Uranus rises after the Sun and sets after the Sun.

   Can’t find Uranus? The 7th planet from the Sun is currently within the constellation of Pisces the Fishes and has recently completed its retrograde motion. Finding Uranus is somewhat of a challenge given that it has an average apparent magnitude of 6, putting it at the naked-eye limit of visibility. However the planet is visible with binoculars as a faint pale-bluish star and its location may be found by using the corners of the Square of Pegasus as ‘pointer stars’. With some planning and a good finder chart like those from the Sky Live web site an observer could make an observation perhaps once a week and follow the motion of the Uranus amongst some of the stars of Pisces.

   This is a short piece from a video I made as part of a live musical performance called “Orbit” that I was part of in May 2011. This is a piece from the much longer tour of the solar system performance and video and shows Uranus and some of its moons as viewed from the Voyager 2 spacecraft.

Neptune at Eastern Quadrature

   Sunday November 29th the position of the planet Neptune with respect to the Earth and the Sun places this ringed planet at what is called eastern quadrature. Neptune is at a 90 degree angle from the Earth – think first quarter Moon as that is a fair comparison of the relative positions.

Saturn at East Quadrature-2015

   Friday August 21st the position of the planet Saturn with respect to the Earth and the Sun places this ringed planet at what is called eastern quadrature. Saturn is at a 90 degree angle from us as this graphic shows. Think first quarter Moon as that is a fair comparison of the relative positions. At this position Saturn follows the Sun across the sky from east to west as the Earth is rotating, meaning that Saturn rises after the Sun and sets after the Sun.

   Where is Saturn now? Saturn is west (to the right) from the planet Saturn and near the eastern side of the constellation Libra the Scales.
