The planet your brother has to reach is 1 light-year from the planet Earth which Approximately 9.461e+12km. But your brother has a spacecraft having a very high speed greater than the speed of light. If we go there with a normal spacecraft having a normal speed less than the speed of light then the time required to reach there and return home is let's say 70 years.  If your brother reaches there and returns home after all work is done then at that time you X ...

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. Yes, we can colonize Mars but it is too difficult to survive due to some issues.  Mars is on the boundary of the Habitable zone. A habitable zone is simply the orbit at a certain distance from the star where a planet or planetary surface can support water with sufficien...
