A dime is 1.8 cm in diameter. Earth's moon is 3.844 x 105 km from Earth and has a diameter of 3.76 x 103 km. At what distance from your eye would you have to hold a dime so that it has the same angular diameter as the full moon (that it would cover the moon.)

ASSIGNMENTS: Video Questions. DO NOT LOSE VIDEO HANDOUTS! Last 20 minutes replayed 12/12, 12/15 after school – if there is interest I can set up a session before school or during lunch. Alternate Observation Assignment will be assigned when I get back tomorrow.

A. Yes, precession will naturally circularize the Earth’s orbit.

B. Yes, precession will eventually reduce the Earth’s axis tilt.

C. No, precession only changes the direction in which the North Pole points, and has nothing to do with the seasons.

D. Yes, precession will make summers occur at the same time, but in what is now the northern spring and southern fall.

E. Yes, but it would take tens of thousands of years, longer than current human history, for this to occur.

Because of precession, someday it will be summer everywhere on Earth at the same time.

Objects are located on the celestial sphere in units of:

A. MilesB. KilometersC. Light yearsD. ParsecsE. Degrees


The angular size of your fist, held at arms length, is about:

A. 1 degreeB. 10 degrees C. 5 inchesD. 10 inches


The apparent size of the moon in the sky is:

A. About ½ degreeB. About 5 degreesC. About 10 degreesD. About a mileE. About 2000 miles (1/4 the earth’s diameter)


What makes Polaris a special star?

A. It is the brightest star in the skyB. It is always directly overhead, no matter where you areC. It is near the axis about which the sky turnsD. Its azimuth (direction) is always due northE. C and D


When an astronomer describes the altitude of something in the local sky, he or she means:

A. How high something is in the sky, in units of miles or kilometers

B. How high something is in the sky, in units of degreesC. The direction toward something– north, south, east, or

west


During the year the Sun appears in front of different groups of stars. What are these called?

A. Circumpolar starsB. Circumsolar starsC. The constellations of the zodiacD. The tropical constellationsE. Solstice stars


When an astronomer describes the azimuth of something in the local sky, he or she means:

A. How high something is in the sky, in units of miles or kilometers

B. How high something is in the sky, in units of degreesC. The direction toward something– north, south, east, or

west


Why are different stars seen in different seasons?

A. The tilt of the Earth’s axisB. Stars move during the yearC. As the Earth orbits the Sun we see the Sun in front of

different constellations D. Because that’s how horoscopes workE. Precession


Why are the Moon and planets seen only in the constellations of the zodiac?

A. The planets all revolve in the same direction around the Sun

B. The planets all orbit in nearly the same plane, and the zodiacal constellations are in that plane.

C. The constellations in the zodiac are the oldest, and the planets have been known from ancient times

D. None of the above reasons


When it is summer in the United States, in Australia it is:

A. WinterB. SummerC. It is always summer in Australia


What causes the seasons?

A. In summer the (whole) Earth is closer to the SunB. In summer the tilt of the Earth’s axis makes the part of the

Earth we are on closer to the SunC. In summer the Sun is up for more hoursD. In summer the Sun climbs higher in the sky so its rays hit

the ground more directlyE. C and D


If the tilt of the Earth’s axis to its orbital plane was 40 degrees, instead of 23 ½, but its distance from

the Sun remained the same, what would happen to the seasons?

A. They wouldn’t change muchB. They would become less extreme–winter and summer

would be more alikeC. They would become more extreme–winter colder and

summer warmerD. The whole Earth would get colderE. The whole Earth would get warmer


A. It was the first star to be cataloged by ancient astronomers.

B. It lies close to the north celestial pole and is therefore very useful for navigation.

C. It is the brightest star in the entire sky.D. It is the brightest star in the northern sky.E. It is visible from both the northern and southern

hemispheres.

What makes the North Star special?


A. Yes, precession will naturally circularize the Earth’s orbit.B. Yes, precession will eventually reduce the Earth’s axis tilt.C. Yes, precession will make summers occur at the same time,

but in what is now the northern spring and southern fall.D. Yes, but it would take tens of thousands of years, longer than

current human history, for this to occur.E. No, precession only changes the direction in which the North

Pole points, and has nothing to do with the seasons.

Because of precession, someday it will be summer everywhere on Earth at the same time.


In the northern hemisphere When is the Sun directly overhead at noon?

A. March 21B. June 21C. July 21D. Never
