The law that states that all planets move in an elliptical orbit around the Sun

The law that describes the speed of planets that orbit the Sun

The law that describes the size of a planet's orbit

The law stating that every piece of matter is attracted to every other piece of matter; the force is directly proportional to their masses but inversely proportional to the square of the distance between them.

Kepler's third law states the closer a planet is to its Sun, the shorter the planet's orbital period (year) and the farther a planet is from the Sun the longer the year. 

• True

• False

What is Kepler's 2nd law?

• The planets orbit in an ellipse

• The plants move faster when they are closer to the sun and slower when they are further from the sun

• The farther a planet is from the sun the slower the orbit

  (P² = a³)

NGSS.MS-PS2-4

• The line along the widest part of an ellipse

• The line that is perpendicular to the major axis and divides an ellipse in half

• The time a given astronomical object takes to complete one orbit around another object

• One-half of the major axis, which runs from the center, through a focus, and to the perimeter; essentially, it is the radius of an orbit at the orbit's two most distant points.
