The distance between Mars and Earth varies depending on their positions in their respective orbits. On average, Mars is about 140 million miles away from Earth. However, during its closest approach, it can be as close as 33.9 million miles.
The closest approach of Mars to Earth occurs every 26 months, when the two planets align on the same side of the sun. The most recent close approach was in October 2020, and the next one will be in December 2022.
During a close approach, Mars appears brighter and larger in the night sky. This is because it is closer to Earth, allowing us to see more surface features and details with telescopes. However, there is no physical interaction between the two planets.
The closest approach of Mars to Earth lasts for a few weeks, as the distance between the two planets slowly increases after the alignment. However, the planet remains visible in the night sky for several months after the close approach.
No, a close approach of Mars to Earth occurs every 26 months. However, the distance between the two planets during these close approaches can vary, with some being closer than others. The last time Mars was this close to Earth was in 2003, and the next time it will be even closer will be in 2287.
