Groups of stars that form patterns

CONSTELLATIONS
Refers to a prominent pattern or
group of stars that is not a
constellation.
ASTERISM
Used to show apparent position of
the stars as seen on Earth.
STAR MAPS OR STAR

are constellations that
never set below the horizon when
seen from a particular location on
Earth. They can be seen in the night
sky throughout the year, while
other constellations are seasonal,
visible only at certain times of year.

ORION

galaxies, gas, dust and other nonEarthly bodies and phenomena.
ASTRONOMY
was a mathematician and astronomer who proposed
that the sun was stationary in the center of the universe
and the earth revolved around it. Disturbed by the
failure of Ptolemy’s geocentric model of the universe to
follow Aristotle’s requirement for the uniform circular
motion of all celestial bodies and determined to
eliminate Ptolemy’s equant, an imaginary point around
which the bodies seemed to follow that requirement,
Copernicus decided that he could achieve his goal only
through a heliocentric model.
NICHOLAS COPERNICUS
Knudstrup, Scania, Denmark—died October 24,
1601, Prague), Danish astronomer whose work in
developing astronomical instruments and in
measuring and fixing the positions of stars paved
the way for future discoveries. His observations—
the most accurate possible before the invention
of the telescope—included
a comprehensive study of the solar system and
accurate positions of more than 777 fixed stars.
