a smaller group of stars within a constellation in a noticable pattern. ex., the big dipper in ursa major, the tea pot in saggitarious
is the angle measured from the zenith from true north to a celestial object. Ex., north=0 degrees, east= 90 degrees, south=180 degrees, west= 270 degrees
latitudinal lines run east and west and circumvent the globe. Measureed in degrees. 10/15 degree increments. maximum latitude is 90 degrees
run north ad south. measured in degrees. prime meridian runs through Greenwich, England, and is at 0 degrees longitude. 15 degrees east and west of the Prime Meridian. International Dateline(where day changes) has longitude of 180 degrees E. or W.
lines running n/s on the globe, measured e/w of the prime meridian, approximately 15 degrees apart from eachother, 24 encircle the earth
the apparent path of the sun. (the earth rotates, giving the illlusion that the sun moves across the sky from the east to the west)
how many degrees are in a circle? how does this relate to astronomy?
360 degrees- the lones of latitude and longitude extend into space
what are the two ways of locating celestial objects in the sky?(2)
1. Declination and right ascension 2. altitude and azimuth
what constellations are currently in the sky?
scorpious, saggittarious, ursa major, capricorn, pegasis, and Cassiopeia
why are vconstellations impportant to astronimers even though they are artificial?
to locate other celestial objects
why do we say a galaxy is natural and a constellation is artificial?
you can't see depth in constellation, they just appear to allign a certian way, but the actual distances may vary.
will someone in earth and space help me on this definition, please?: what is the scientific significance of zodiac constellations? thanks
they are found along the ecliptic
what zodiac constellations are presently in the night sky?
libra, scorpius, saggitarious, capricorn, aquarious
