Mars Opposition

Mars Opposition & Facts

 

For planets outside the Earth’s orbit, like Mars, the months around Oppositions are the best time to observe these planets. An opposition occurs when the planet is opposite from the Sun relative to the Earth.

At Opposition, the planet will rise as the Sunsets and will set as the Sun rises providing an entire night of observation. Also at Opposition, the planet comes physically closest to the Earth in its orbit so it appears as large as possible.

The next Mars opposition occurs: Tue Oct 13, 2020, 19:13:04 GMT-0400 (Eastern Daylight Time)
