There are more stars than all of the grains of sand on earth.

You can see stars from the bottom of a well even in day light.

Stars with really strong gravity cause themselves to become smaller and smaller and eventually turn into black holes.

Stars come in different colors; hot stars give off blue light, and the cooler stars give off red light.

In honor of the original thirteen states, the U.S. $1 bill has the following on the back: 13 steps on the pyramid. The motto above the pyramid has 13 letters (annuity coatis). E pluribus Unum, written on the ribbon in the eagle's beak, has 13 letters. 13 stars appear over the eagle's head. 13 stripes are on the shield. 13 war arrows are in the eagle's left talon.

All of the stars comprising the Milky Way galaxy revolve around the center of the galaxy once every 200 million years or so.

Until the mid sixteenth century, Comets were believed to be not astronomical phenomena, but burning vapors that had arisen from distant swamps and were propelled across the sky by fire and light.

Our galaxy has approximately 250 billion stars and it is estimated by astronomers that there are 100 billion other galaxies in the universe.

A galaxy of typical size, about 100 billion suns produces less energy than a single Quasar.

A Comet's tail always points away from the sun.

A Pulsar is a small star made up of neutrons so densely packed together that if one the size of a silver dollar landed on earth, it would weigh approximately 100 million tons.

The Star Alpha Herculis is twenty five times larger than the circumference described by the earth's revolution around the sun. This means that twenty five diameters of our solar orbit would have to be placed end to end to equal the diameter of this Star.
