Which motion does Earth make once every 24 hours?

• Revolves once around the sun

• Rotates once on its axis

• Makes one orbit of the sun

• Passes by Mars in its path

Millions of pieces of rocky material of various sizes orbit the Sun between the orbits of Mars and Jupiter. These objects are known as -

• Meteors

• Asteroids

• Planets

• Comets

What would happen if the Sun's gravity suddenly stopped?

• The celestial objects with masses less than the planets would begin orbiting the Sun instead.

• The planets would crash into the Sun.

• The planets would move away in a straight line away from the sun.

• The planets would no longer follow circular orbital paths, but would follow elliptical orbital paths.

What can scientists assume about the gravitational pull on a small planet located a great distance from the Sun?

• The pull will be the same as on Earth.

• The pull will be strong.

• The pull will be weak.

• More information is needed to answer the question.

What competes to keep celestial bodies in orbit?

• the force of gravity and mass

• the force of Newton's law and the force of momentum

• The force of gravity and distance

The four planets that orbit closest to the Sun are best described as -

• mostly made up of gases.

• have rings similar to Saturn's.

• having a rocky and terrestrial surface.

• being composed entirely of water.

Planets vary as they get farther from the Sun. As a rule, the farther a planet's orbit from the sun, -

• the greater the planet's diameter.

• the longer it takes to orbit the Sun.

• the rockier the surface of the planet.

• the greater the planet's surface temperature.
