A. They can fall into circular orbits.
B. They can follow erratic orbits that take on different shapes.
C. They can spiral into the sun.

Choices: floated in outer space, heliocentric, traveled along a circular path, was just another planet, geocentric, were fixed to an outermost sphere

6.)Which statement describes the area swept out by a line between a planet and the sun at equal times as the planet moves along its orbit?(1 point)
A. It is proportional to the distance between the sun and the planet.
B. It decreases as the planet moves closer to the sun.
C. It changes shape but always remains constant.
D. It increases as the planet moves closer to the sun.

7.)Which of the following is the best definition of Newton's theory of universal gravitation?(1 point)
A. Every object attracts every other object in the universe, with a force that increases as the objects' masses decrease and the distance between them increases.
B. Every object attracts every other object in the universe, with a force that increases as the objects' masses increase and the distance between them decreases.
C. Every object is attracted to the Earth with a force that increases with increasing mass and distance.
