Which planets in our solar system are considered to be rocky?
Mercury, Venus, Earth, Mars
Venus, Earth, Mars, Jupiter
Saturn, Uranus, Neptune, Pluto
Venus, Earth, Mars, Jupiter
Why is Venus so much hotter even though it is further away from the Sun?
Venus doesn’t have an atmosphere which causes the planet to become much hotter than other planets.
Venus’ atmosphere is so dense that heat is trapped and can barely escape, making it hotter than other planets.
Venus has different layers in our atmosphere which causes Venus to be hotter.
Venus atmosphere is so thin that heat is able to pass through and make the planet hotter.

The current model of our Solar System is called the heliocentric model, which means the Sun is at the center. Before scientists developed the current model, which is best supported by evidence, what was believed to be the center of our solar system?
The Solar System had no center because all of the planets' orbits were random.
A star other than the Sun was the center of the Solar System.
A black hole was the center of the Solar System.
Earth was the center of the Solar System
Which of these choices states Newton’s law of universal gravitation?
As a planet moves around its orbit, the planet sweeps out equal areas in equal amounts of time.
The orbit of a planet, or other body, around the sun is an ellipse, with the sun at one focus of the ellipse.
The square of a planet’s orbital period is proportional to the cube of the planet’s mean distance from the sun.
Gravitational force increases as the mass of an object increases or as the distance between two objects decreases.
Which of those objects has the greatest gravitational force?
Asteroids
The Sun
Moons
Planets
