Mars, nearest planet to our planet, came closer to the Earth on July 31. It came closest to Earth after 15 years. Last time, it came close in 2003 at 55.7 million km distance from the Earth. On July 31, it came closer at a distance of 57.6 million km. Next time Mars will come close to Earth at the same distance as it was in 2003 only on August 29, 2287.
Mars is the nearest planet to the Earth. Mars comes closest to the Earth when it is at opposition. Mars at Opposition was explained by Dr. Debiprosad Duari, Director of Research and Academics at M.P. Birla Institute of Fundamental Research, Kolkata. He explained that distance Mars orbit is greater than Earth orbit. As the distance of orbit from the Sun increases, the time to take rounds around the Sun also increases. Earth takes little more than 365 days to orbital the Sun and Mars takes 687 days. On every 26 month or so, Earth passes between the Mars and the Sun due to Orbital speed and period. When Mars and the Sun come exactly opposite to the Earth, it is called Mars at Opposition.
This time Mars was at its Opposition on July 27. From then, it was very bright and was visible roughly after sunset. After this, Mars will be at opposition on October 6, 2020, at 61.76 million km distance from the Earth.
