Mars Hasn't Been This Close To Earth In Over A Decade
Don't miss it because it won't be this close again until July 2018.By Ben Lawson | May 21, 2016
Saturday night, Mars will appear to be the brightest it's been in more than 10 years.
The red planet will be within 48 million miles of Earth from May 21 until June 12. The last time it was this close was in November 2005.
Mars passes close enough to Earth to be seen every other year. It's called Mars opposition because the planet appears to be directly opposite of the sun, near the moon in the sky.
