MARS OPPOSITION SUMMARY

SUMMARY FOR VENUS AS AN EVENING STAR

Here is today’s planet forecast:

Morning Sky

Mercury and Saturn rise during morning twilight, immersed in the bright light of the approaching sunrise.  Mercury rises only 28 minutes before the sun, followed by the Ringed Wonder about 15 minutes later.

The inner-most planet reaches superior conjunction on the far arc of its orbit on March 17th, then races into the evening sky for its best evening appearance of the year.  Its evening greatest elongation occurs on April 11th.

Saturn is emerging from its conjunction about a week ago.  It’ll make its first appearance in a darker sky around equinox time.

Evening Sky

After sundown, brilliant Venus is nearly 20° above the west-southwest horizon and 4.2° to the lower right of bright Jupiter.  The night’s two brightest starlike bodies are near each other for the next two weeks. Venus passes closely to Jupiter on March 1st.

While the two planets appear close together in the sky, they are millions of miles apart in space.  This evening Venus is 129 million miles away, while Jupiter is over four times more distant than the Evening Star.

Both planets are in the same binocular field of view.  Some of Jupiter’s largest satellites might be visible.

The waxing crescent moon, 37% illuminated is high in the southwest.  As the sky darkens, look for the Pleiades star cluster, 9.2° to the upper left of the crescent.  It may be necessary to block the moon with your hand or the edge of a building to see the cluster.  A binocular is helpful to find the stellar bunch with this level of moonlight.

Mars is nearly 30° to the upper left of the lunar crescent and over 70° up in the south.   The Red Planet is marching eastward against Taurus and approaching the Bull’s horns.  It passes Elnath, the northern horn on March 9th, between the horns, and then past Zeta Tauri, the southern horn, on March 14th.

The moon is near Mars in two evenings.  Look each clear evening to witness the changing planet dance in the western sky and the moon’s eastward passage.
