The altitude of Polaris measured by an observer at the Tropic of Cancer is 1) 15° 2) 23.5° 3) 66.5° 4) 90°
9966 [12]

Answer: 23.5\°

Explanation:

The Tropic of Cancer is one of the parallels (imaginary line around the Earth parallel to the equator) located in the northern hemisphere (currently its latitude is 23.43672\° \approx 23.5\°).

It is called "Cancer" because a long time ago, when the summer solstice occurred in the northern hemisphere (on June 20th or 21st), the Sun was in the constellation Cancer (the crab).

Now, if we were just in the North Pole, Polaris would by exactly over our heads (90\° over the horizon), but as we go south and find the Tropic of Cancer parallel, Polaris altitude will be approximately at an angle of 23.5\° over the horizon.

Hence, the altitude of Polaris measured by an observer at the Tropic of Cancer is 23.5\°.
