As Mars Makes Closest Approach To Earth In 15 Years, You Can Spot The Solar System’s Largest Volcano
This evening the planet Mars will be 38.6 million miles (or 62.1 million kilometers) away from Earth, the two planets closest approach in 15 years. The closest possible encounter between Mars and Earth happens when Earth is furthest away from the Sun and Mars is closest to the Sun. Earth’s previous closest approach with Mars was recorded in 2003 when Mars was 34.6 million miles (55.7 million km) away. The next time Earth and Mars will be that close is in September 2035.
