How is Earth's orbit around the Sun similar to the orbits of other planets around the Sun?

• Each planet's orbit is determined by how fast it rotates.

• Each planet's orbit takes about the same amount of time.

• Each planet's travels the same distance in it's orbit as the other planets.

• Each planet's orbit is controlled by the pull of the Sun's gravity.

Astronomers track asteroids as they move throughout our solar system. The path of an asteroid is illustrated below. What force is most responsible for the path this asteroid follows?

• gravitational pull from the center of the Milky Way galaxy

• Newton’s 1^st law of motion that says objects want to travel in a straight line

• 
  centripetal force that governs objects will move in circular patterns

• the gravitational pull from the sun

What criteria did the student most likely use to separate the two sets of planets?

• planets with and without moons

• planets with water and planets without water

• terrestrial planets and gas giants

• planets with atmospheres and planets without atmospheres

Which best describes the physical properties of the comets?

• Objects made of dust and ice orbiting far from the sun that emit gas and form a tail as they move closer to the sun.

• Natural, solid, and rocky objects that orbit a planet.

• Celestial bodies that orbit a star at various distances and have significant mass.

• Space objects that enter Earth's atmosphere at high speeds and burn up.
