For four hours, beginning on Monday night, July 30, at 10:00 p.m., Griffith Observatory provides a rare opportunity for you to see the planet Mars at its closest. On that evening, Earth and Mars will be 35.8 million miles from each other, the closest that they have been since the historic 34.6 million-mile close approach in August, 2003. By a celestial coincidence, at the same time, Mars will be at its very best position for viewing through a telescope from Los Angeles, as it crosses the meridian and appears highest in the southern sky. The next similar close approach won’t happen until September 11, 2035, when Mars will be 35.4 million miles away.

NOTE: Unlike an eclipse, Mars will not change in appearance during the course of the evening.
