Front

Kepler's 2nd Law deals with: the shape of the planets' orbits, the speed/area the planet travels, the length of time it takes the planet to orbit the sun

Front

Kepler's first law states that the orbits of the planets are oval in shape or

Back

ellipses

Front

The farther away a planet is from the sun, the _______ it takes it to orbit the sun once.

Back

longer

Front

The path a planet travels around the sun is called its

Back

orbit

Front

What does Kepler's 1st Law state? Options: all planets move in elliptical shaped orbits around the sun, all ellipses have foci, not all ellipses have the same eccentricity, the sun is located at one of the foci

Back
