Latitude & Longitude
Not a lie, just s t r e t c h i n g the truth. All maps are really projections, showing a round Earth as flat.
In space, there is no such thing as “up” or “down”!
Where do latitudes originate? Angles NORTH or SOUTH of Equator. Create parallel lines.
Where do longitudes originate? Angles EAST or WEST of Prime Meridian. Meet at Poles, widest at Equator.

Latitudes and Longitudes from Space
From which New York State location would Polaris be observed to have an altitude closest to 43° above the northern horizon? (1) Binghamton (3) Watertown (4) New York City (2) Utica
How can we determine longitude? Earth constantly rotates, Let’s calculate its rate… Longitudes can be determined from time. (And time from longitudes!) The sun only faces one side of the Earth at a time (12 noon), hours change East or West of the sun.
15 o / hr ! 12 PM (Noon) Later (past noon) Earlier (not yet noon) West is earlier (AM), and east is later (PM)! If it is 12 PM (noon) at 0 o, what time is it at 180 o on the other side of the Earth? 12 AM (Midnight)!
The world map above marks location A, in Angola. If it is 3 PM there, what time is it by the star in Rio de Janeiro, Brazil 1) 11 AM 3) 7 PM 2) 12 PM (noon) 4) 6 PM
As Earth rotates (from West to East), the sun APPEARS to move through the sky from East to West! Where does the sun rise & set? WestEast
In fact, everything APPEARS to move through the sky from East to West in circular paths!
Everything appears to move except… POLARIS (The North Star)
How do you find Polaris?
Polaris is the last star in Ursa Minor (The Little Dipper). Ursa Major (The Big Dipper) helps point you to Polaris.
The height of Polaris in the sky is equal to your latitude. (ONLY NORTH of the Equator!) Polaris is over the North pole. It ALWAYS points you north. (If you are north of the Equator!)
The diagram shows an observer on Earth viewing the star Polaris. What is this observer’s latitude? (1) 38° N (3) 52° N (2) 38° S (4) 52° S
The altitude of Polaris = latitude North of Equator! Polaris is at 0 o Angle Equator = 0 o latitude Polaris is at 30 o Angle New Orleans = 30 o N Polaris is at 90 o Angle North Pole = 90 o N
What happens to height of Polaris as you move toward the North pole? How about if you move SOUTH from the pole? Where would you see Polaris if standing AT the North Pole?
Polaris is at a 90 o angle above the North Pole. The North pole is 90 o North latitude. Polaris appears to be at a 0 o angle to a person at the Equator (0 o latitude).
Which diagram best represents the view of Polaris to an observer located at the Earth’s Equator?
