  Mars is the 4th planet of our solar system and the nearest planet of Earth. 1610 was the year when Galileo Galilei discovered Mars with telescopic observation, the distance between the sun and mars is 228.19 million km. Behind the mars, there is the belt of so many Asteroids. The orbital period is 687 days which is quite more than the earth’s orbital period. Planet Mars is surrounded by so many artificial ( manmade) satellites. But mars have 2 natural satellites named Phobos and Deimos. Colonization on a different planet is also known as the Space settlement it is the political concept of space law for human habitation and the taking advantage of all-natural resources of that planet where we want to colonize.

The planets regularly appear to pass each other in the solar system, with the positions of Jupiter and Saturn being aligned in the sky about once every 20 years. But What was special in this year’s conjunction? It’s been nearly 400 years since the planets passed close to each other in the sky, and nearly 800 years since the alignment of Saturn and Jupiter occurred at night, as it will for 2020, allowing nearly everyone around the world to witness this “great conjunction.” History of Jupiter and Saturn co...
