Mars Oppositions

When Mars is at opposition on October 13, 2020 the red planet will be in the constellation of Pisces. This is another perihelic opposition and the red planet is expected to shine at -2.7 magnitude. The U.S. Mars InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) landed on November 26 2018.

Check out Astra's Mars at Opposition 2018 page for more information on oppositions.

Next Mars Opposition: October 13, 2020

Past Oppositions:
July 27, 2018 Capricornis.
May 22, 2016 the planet was located in the constellation of Scorpius.

The 2003 apparition of Mars was purported to be the closest opposition to Mars in recorded history. According to sources, Earth came closer to Mars than it has been since 12,000 BC! The angular diameter of Mars was greater that 25 arc seconds, allowing amateurs to see and record the best detail ever.

The Three Faces of Mars page, in part, takes its name from the " Face on Mars" feature taken by the spacecraft Viking 1 orbiter many years ago.

Today, ESA has created a movie of the martian feature, the Cydonia face. This link will take you to the movie, Cydonia's 'Face on Mars' in 3D animation from the European Space Agency

Because every 26 months Earth passes the planet Mars that orbits the Sun at a greater distance, this brings the two planets to their closest distance. We can't afford to miss even one opposition, because every opposition is an opportunity!
