Orbits, Effects Sun-Earth-Moon

What does the distance "d" represent in the diagram of the ellipse with foci A and B?

• The distance between the two foci of the ellipse

• The length of the major axis

• The circumference of the ellipse

• The distance from the center to one focus

What does Kepler’s first law state about the orbits of planets?

• The orbits are perfect circles

• The orbits are ellipses with the Sun at one focus

• The orbits are squares

• The orbits are random shapes

What does Kepler's third law state?

• The time a planet takes to complete one orbit is related to its average distance from the Sun.

• The time a planet takes to rotate on its axis is related to its size.

• The time a planet takes to complete one orbit is related to its mass.

• The time a planet takes to complete one orbit is unrelated to its distance from the Sun.

What is the term for the ratio of the distance between the foci and the length of the major axis of an ellipse? It will also describe how circular of an orbit a planet has.

• Eccentricity

• Coma

• Gravity

• Orbit

If an ellipse has an eccentricity of 0.01, how would most people describe its shape?

• As a circle

• As a straight line

• As a highly flattened ellipse

• As a square

Over time, what causes the eccentricity of Earth's orbit to change?

• The weak gravitational pull of the other planets

• The Sun's heat

• The Earth's rotation

• The Moon's orbit

What is the current angle of Earth's axial tilt (obliquity)?

• 15.0°

• 23.5°

• 30.0°

• 45.0°

Which of the following best describes the effect of a greater angle of Earth's axial tilt?

• Less difference in extremes between summer and winter

• Greater difference in extremes between summer and winter

• No change in seasonal temperature differences

• Shorter duration of seasons

Why does winter occur in the northern hemisphere when it is tilted away from the Sun?

• The northern hemisphere is closer to the Sun.

• The northern hemisphere receives less direct solar energy.

• The rotates faster.

• The northern hemisphere is covered by clouds.

Where are most asteroids found in the solar system?

• Between Mars and Jupiter

• Between Earth and Venus

• Beyond the orbit of Neptune

• Inside Mercury’s orbit
