Night Sky



The night sky is filled with thousands of points of light twinkling in the darkness. Most are stars-gigantic suns so distant they look tiny. About 2000 stars are visible to the naked eye, but there are trillions more out in space.
Slightly brighter than stars are some of the planets that circle the sun.
The brightest object of all in the night sky is the nearest to earth - the Moon.

PATTERNS OF STARS

To find their way around the night sky, astronomers divide the sky into 88 patterns of stars, or constellations. Many constellations still have the names of the ancient Greek mythical heroes and creatures they were given long ago,such as Orion the hunter
There is no particular connection between the stars in a constellation; they just appear close together in the sky.
