Exam 1: Charting the Heavens: the Foundations of Astronomy

The south celestial pole is located at a declination of - 90 degrees.

The fact that the Earth has moved along its orbit in the time it took to rotate once is the reason for

Over the course of the year, the Sun's noon altitude varies by degrees.

If two observatories on opposite sides of the Earth were to measure the position of a star to calculate its parallax, then the diameter of the Earth would be the _ .

As it orbits the Earth, the Moon appears to move its own diameter (0.5 degrees) eastward every hour against the background stars.

The time for the Moon to orbit the Earth, relative to the distant stars is the .

The apparent angular shift of any object across a distant background, when viewed from two different places, is called shift.

The last quarter moon rises tonight about midnight; when will it rise, and what will its phase be tomorrow night?

A solar eclipse can only happen during a

How far above and below the celestial equator can the Sun move?

Why is Polaris not always the pole star, and when does it get another chance?

How is right ascension similar to longitude on Earth?

Constellations are close clusters of stars, all at about the same distance from the Sun.

Latitude and right ascension are coordinate systems used to find objects on the celestial sphere.

Describe how Eratosthenes measured the circumference of our planet.

The twelve constellations through which the Sun passes are signs of the _ .

A star with a declination of +60.0 degrees will be

What will occur when the full moon is on the ecliptic?

If Taurus is now rising at sunset, which constellation will rise at sunset next month?

The star Wolf 1061 has a parallax of 2.34 arc seconds, while the star Ross 652 has a parallax of 1.70 arc seconds. What can you correctly conclude?
