China has a plan to launch a new project an “Artificial Moon” that will light up the skies as far as 50 miles around. The artificial Moon will be eight times brighter and stronger than real Moon. It will be realized in 2010 in the southwestern city of Chengdu.
This question will be interest to many people, the distance between Earth and Mars during the longest lunar eclipse. This information has provided us NASA (National Aeronautics and Space Administration).
Here is the answer, the distance between Mars and Earth has been 35.8 million miles, yea it seems very close because we have witnessed this rare phenomenon during the longest lunar eclipse. But actually, 35.8 million miles is not so close as we consider, ops just a minute but not in Space.
So according to NASA Mars was 35.8 million miles from Earth, which was the closest it had been to Earth in 15 years. What does this mean for sky watchers? It means the mysterious planet Mars appeared super bright, and with its orange-red color.
What Do We Understand to Say Closest 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”, explains NASA. That’s what was happening on the early morning hours of July 31.
But this is not the end, now you may ask: Is 35.8 million miles the closest Mars has ever been to Earth?
We are in a hurry to answer the question “NO”, this is not the closest approach to Earth. In 2003 Mars was 34.6 million miles from Earth and the closest it had been in nearly 60,000 years.
You know the painful question is that this type of approach won’t happen 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.
