Mars Opposition 2010

http://apod.nasa.gov/apod/

In this picture Mars is at opposition. This means it is opposite the Sun in respect to Earth's sky. It is easy to spot even for a novice astronomer because it is closest to the fool moon. Mars is still over 99 million kilometers away but still not particularly close approach for the famous Red Planet. In this picture we can see a reddish planet very clearly. This is an example of the telescopic images possible in the coming days which means a lot more clear pictures of this red planet. In the picture you can even see the north polar cap of this red planet, that is how clear the picture is. It is the white part of the planet in the upper right hand corner. This planet is also about 14 arcseconds in angular diamiteter relitivly one hundreth of the size of the full moon.
