_______ is the property of an object that leads it to resist any change in motion
Kepler's First Law

Kepler's Second Law
As the planet orbits around the Sun, the planet sweeps out an equal amount of area in an equal amount of time.
Kepler's Third Law
Describes the relationship between the average orbital radius and the period of a planet.
Newton's first law
An object at rest remain and an object in motion remains in motion UNLESS it experiences an unbalanced force. Also called the Law of Inertia.
Newton's second law
Acceleration is produced when a force acts on a mass, the greater the mass, the more force is required to accelerate the object.
Newton's Third Law
All forces come in pairs. The two forces in a pair act on different objects and are equal in strength and opposite in direction.
A planet's furthest point from the sun.
A planet's closest point to the sun.
The quality of being eccentric.
a body of coherent matter, usually of indefinite shape and often of considerable size
