Today the planet Mars will be at its closest point to the Earth.

Mars was at opposition two days ago, but not at its closest. Close approach of the two planets is not necessarily on the same day as opposition, but can vary up to two weeks. This year sees the two planets approaching to 99,331,411 km (61,721,554 miles) at 07:01HST. At this distance the red planet will show a disk 13.89″ arc-seconds across in the eyepiece.

All month Mars will be visible throughout the night, high in the sky at midnight. This is the time to enjoy observing our closest neighboring planet while it is nearby and high in the night sky.
