35.8 million miles (57.6 million km) is definitely not what most of us would consider “close.” But in planetary terms, close is definitely relative! On July 31, Mars will be 35.8 million miles from Earth, which is the closest it has been to Earth in 15 years. What does this mean for sky watchers[/img]

“What defines a “close approach?” The minimum distance from the Earth to Mars is about 33.,9 million miles and does not happen very often. Because Earth and Mars have elliptical orbits and are slightly tilted to each other, all close approaches are not equal. When Mars slowly approaches what astronomers call opposition, it and the Sun are on opposite sides of the Earth. Earth and Mars align in opposition about every two years (fun fact: this is why most NASA missions to the Red Planet are at least two years apart – to take advantage of the closer distance). Opposition to Mars is at its closest to the Sun every 15 to 17 years, when excellent views of the Red Planet from Earth can occur. This is what is happening on the early morning hours of July 31,” the message says.

It means that if you have clear skies where you live, go outside on the overnight hours of July 30 or early morning hours of July 31 and look up. The planet will be brighter than usual and will have an orange or red haze. You can also look through a telescope. If weather is bad where you are, NASA will be streaming live from the Griffith Observatory.

It is noted that35.8 million miles is not the closest Mars has ever been to Earth. In 2003, Mars was 34.6 million miles from Earth and the closest it had been in nearly 60,000 years. This type of proximity won’t occur again until 2287. But, there will be another close approach in October 2020 when the distance between the Red Planet and Earth will be 38.6 million miles.

As it was reported earlier, Elon Musk’s Tesla roadster, which launched on top of SpaceX’s Falcon Heavy a day before, is going farther out into the Solar System than originally planned. The car was supposed to be put on a path around the Sun that would take the vehicle out to the distance of Mars’ orbit. But the rocket carrying the car seems to have overshot that trajectory and has put the Tesla in an orbit that extends out into the asteroid belt between Mars and Jupiter.
