Nothing captures the imagination more than the thought that there might be other life in the universe -- other life than ours, alien life, life on an exoplanet.  Science evolves through an ever-improving ability to measure.  Exoplanets have now been found because we have an ever improving ability to scan the heavens, to see into the depths of space and to distinguish more diminutive effects at these vast distances that tell us about what is going on around distant suns.

NOTE: many vCalc equations are embedded throughout vCalc descriptive pages like this page.  Even though they may not stand out in the text, if you hover over the name of an equation it will likely be linked to an actual, pop-up executable equation. For example:

One of the recent discoveries in the area of exoplanets is Wolf 1061.  See THIS LINK to find out about an exoplanet that is within human reach.

In all the discussion of stars and their exoplanets, the question comes up "Will humanity be able to visit these exoplanets."  vCalc's collection of distance constants and distance equations she'd some light on the relative distances.
