Exam 2: Patterns in the Skymotions of Earth

Kepler's third law holds true mathematically only if the period is expressed in years and the semimajor axis is expressed in AU.

At what time does the waxing gibbous phase rise?

What time does a third quarter Moon rise?

The figure below shows the different phases of the Moon.Label each phase of the Moon.Approximately what time would the full Moon rise above your horizon? The third quarter Moon? The new Moon? The first quarter Moon?

Planets orbit the Sun on circular orbits.

Planets with circular orbits travel at the same speed at all points in their orbits,whereas planets with elliptical orbits change their speeds at different points in their orbits.

What would be the effect on the seasons if the tilt of the Earth's axis were 10° rather than 23.5°?

Assume you are observing the night sky from a typical city in the United States at a latitude of +40°.Use the figure below to determine which constellation of the zodiac would be rising at 10 P.M.in May.

Constellations are arbitrary groupings of stars in the sky.

Johannes Kepler found that a planet's period was inversely proportional to the cube of its semimajor axis.

The fact that we always see the same side of the Moon indicates that the Moon does not rotate about an axis.

As we move farther from the Sun,the circumferences of planetary orbits are larger and the speeds at which planets travel increase.

The apparent path of the Sun across the celestial sphere during a year is called the:

Kepler's third law is a relationship between an orbiting object's:

On what place(s)on Earth can you stand and have the great circle of the celestial equator be at the same height relative to your horizon for all 360° of its circumference?

Johannes Kepler obtained accurate data on the positions of the planets in the sky over time,which Galileo used to prove that planets revolved around the Sun.

In regard to the phase of the Moon,the term waxing means:

When the Northern Hemisphere experiences summer,the Southern Hemisphere experiences:

Solar and lunar eclipses are rare because:

Which of the following is TRUE about a comet that is on an elliptical orbit around the Sun?
