Going through pages and pages in Stumble Upon (most of them are worth it) I found this wonder:
The Neave Planetarium is an online planetarium with which we can know more about the stars, planets and constellations that are found in the sky at any given moment and which we can see with the naked eye.
It’s as simple as choosing our location and the time in the application, and going out to see the stars.
When you want to know something about a given star or planet, locate it on the online planetarium and click it so that information can be displayed about it like its name, its constellation (if it is a star), its brilliance (magnitude) and its distance from Earth.
An excellent tool for those who love to look up and admire what’s in the sky.
