How does the heliocentric model of planetary motion explain a star's path across the night sky?
Ⓐ The sky is fixed and rotates around Earth.
Ⓑ Earth moves along its orbit daily to follow the stars.
Ⓒ The rotation of Earth makes objects in the sky appear to move.
Ⓓ Each star creates a different amount of light, imitating movement.
Ⓒ The rotation of Earth makes objects in the sky appear to move.
Seasons are affected by the __________and the amount of solar energy the area receives.
What is the tilt of the Earth's axis?
There are eight planets in our solar system, each orbiting the Sun at varying speeds and distances. Venus and Mercury are the only planets in our solar system that do not have moons. Which of the following best explains why Venus and Mercury do not have moons?
Ⓐ Venus and Mercury have no gravity.
Ⓑ Venus and Mercury are too hot to keep moons in orbit.
Ⓒ Venus and Mercury travel too quickly around the Sun to attract moons.
Ⓓ Venus and Mercury have a gravitational pull that is weaker than the gravitational pull of the Sun.
Ⓓ Venus and Mercury have a gravitational pull that is weaker than the gravitational pull of the Sun.
How do asteroids and comets differ from each other?
Ⓐ Asteroids lose mass over time, while the mass of a comet remains constant.
Ⓑ Asteroids are composed mostly of rock and metal, while comets are made of ice and dust.
Ⓒ Asteroids orbit the Sun at a variety of angles, while the orbits of comets are close to the ecliptic plane.
Ⓓ Asteroids are generally found at the edge of the Solar System, while comets are typically found between Mars and Jupiter
Ⓑ Asteroids are composed mostly of rock and metal, while comets are made of ice and dust.

Ⓐ The Sun consists primarily of gases.
Ⓑ Many objects in space are spherical in shape.
Ⓒ Planets revolve around an object of greater mass.
Ⓓ Planets form by small masses combining into larger masses.
Ⓐ The Sun consists primarily of gases.
Planet that has the shortest day.
What is Jupiter?
A rocky and metallic mass that orbits the sun.
What is an asteroid?
