What could be a possible scenario for such an adventure in a near In this article, we examine the possibility of or even distant future? And what could be interstellar travel to reach some exoplanet the reality of UFOs – Unidentified Flying orbiting around a star, beyond our Solar Objects – that get reported in the media system. Such travels have been in the realm from time to time? of science fiction for long. However, in the last 50 years or so, this question has gained further impetus in the mind of a man on the 1 Introduction street, after the interplanetary travel has become a reality. Of course the distances to In the last three decades many thousands of be covered to reach even some of the near- exoplanets, planets that orbit around stars est stars outside the Solar system could be beyond our Solar system, have been dis- arXiv:1308.4869v2 [physics.pop-ph] 6 Dec 2019 hundreds of thousands of time larger than covered.
