The Closest Time-Mars and Earth

Maybe we have watched many planetary shows in 2011. But recently you will have good time to watch the rare shows.  February’s spectacular planetary show continues. After Venus and Jupiter lined up in the night sky last week, the distance between Earth and Mars is now shrinking to its smallest in more than two years. On March 3 Mars will be in opposition to the sun, providing excellent opportunities for viewing the Red Planet. March is also a good month for us to watch the spectacular planetary shows, March 5 is the closest time for the Mars and Earth.

The celestial event known as Mars opposition occurs whenever Earth passes between the sun and the Red Planet, approximately once every two years and two months. This makes Mars visible opposite the sun in the Earth’s sky, which is a great time to view the Red planet because the sun’s rays illuminate the full face of Mars. Because the two planets’ orbits regularly bring them close together, it also provides a good time to launch Mars missions such as the recent Mars Science Laboratory.
Mars and Earth will actually be at their closest on March 5, so you have a decent chance to catch the Red Planet anytime in the next few weeks.

How to Watch

To spot Mars with your naked eye, look for a bright orange-red dot in the eastern sky shortly after the sun sets. The planet, which can be distinguished from stars because it doesn’t twinkle, will rise to its highest position in the southern sky around midnight.

Those with a modest-sized telescope should have good views of Mars’ surface features, including its white polar caps.

Anyone without access to a telescope can catch a live feed of the opposition event from the Slooh Space Camera on March 3 starting at 8:00 p.m. PST. Come back tomorrow evening to our site for an embedded video from Slooh. The Slooh show will feature commentary by the organization’s Patrick Paolucci, Astronomy Magazine columnist Bob Berman, and some special guests.
