WebIf p = 1″ (one second of arc), the distance of the star is 206,265 times Earth’s distance from the Sun —namely, 3.26 light-years. This unit of distance is termed the parsec, defined as the distance of an object whose parallax equals one arc second. Therefore, one parsec equals 3.26 light-years. Since parallax is inversely proportional to ... WebAssuming you mean crewed exploration, we are extremely far from "stellar traversal". Primary technological impediments: Universal speed limit of 'c'. (FTL travel is not possible.) Interstellar distances are vast. Transit time to even the nearest stars at 0.01c (impossible with current technology) is still much greater than the human lifespan.
