Parallax space definition
Webparsec, unit for expressing distances to stars and galaxies, used by professional astronomers. It represents the distance at which the radius of Earth’s orbit subtends an angle of one second of arc. Thus, a star at a distance of one parsec would have a parallax of one second, and the distance of an object in parsecs is the reciprocal of its parallax in … WebThe distances in space are a little hard to understand, but astronomers have interesting ways of figuring it out. One way is using what's called stellar parallax. A very simple …
