The place where a planet is farthest away from the Sun in its orbit around the Sun is called the

• aphelion

• perihelion

• spherical

• elongated

• circular

• spiral

Which is NOT one of Kepler's laws?

• Planets travel in an ellipse

• Planets closest to the sun travel faster

• The farther a planet is from the sun, the longer it takes to orbit

What will result in the most eccentric elliptical orbit

• when the focal points are closest together

• when the focal points are on top of one another

• then the focal points are farthest apart

What are Kepler's three laws of planetary motion?

• Half of the shortest diameter of an elliptical orbit

• By measuring the average distance from the sun and using the law of harmonies formula T^2=k*r^3

• By dividing the distance between the two foci by the length of the major axis.

• The law of ellipses 2. The law of equal areas 3. The law of harmonies

What is the law of ellipses?

• A line that connects a planet to the sun sweeps out equal areas in equal time intervals.

• Planetary orbits are shaped like ellipses, with the sun located at one of the two foci.

• The law of ellipses 2. The law of equal areas 3. The law of harmonies

• By observing the shape and size of their orbits, as well as the time it takes to complete one orbit.

What is the law of equal areas?

• By measuring the average distance from the sun and using the law of harmonies formula: T^2 = k * r^3.

• The time it takes for a celestial body to complete one orbit around another.

• By measuring the distance between the two farthest points and the two closest points on the orbit.

• A line that connects a planet to the sun sweeps out equal areas in equal time intervals
