Mars at Opposition

Last night was the big night to see Mars up close. Ok – relatively close anyway. What is opposition you ask? When Mars is at opposition it means that it is directly opposite the sun relative to us. As you can see here, on April 8th the sun is directly opposite Mars from our perspective. It’s about 57 million miles away, not the closest it can get, but not too bad.

As you can see, in 2003 Mars was very close, at 35 million miles. What this means for us observers is that Mars is bigger! We’re able to see more surface features and polar ice caps. Some may even be able to see clouds!

I went out tonight with my 90mm refractor. Unfortunately I didn’t bring a powerful enough eyepiece outside with me and by the time I went back in to get one the clouds rolled in. Such is observing in Wisconsin.

Try observing Mars this week – do some sketching at the eyepiece! Try adding a filter, green to bring out the polar ice caps. You could get out your smart phone and try some through the eyepiece photography! If you’re really busy you could spot Mars over the trees on your way home and take a moment to smile at our planetary neighbor.

It’s all good.
