In a science class, students are learning about how gravity influences the motion of celestial bodies within our solar system. To illustrate this, a diagram showing the interactions between various planets and the Sun is displayed. Which statements accurately describe the effects of gravity on the motion of celestial bodies in our solar system? Select ALL that apply.
Increasing the mass of the Sun would decrease the orbital speed of the planets around it.
The greater the mass of a planet, the stronger its gravitational pull is on neighboring celestial bodies.
The farther a planet is from the Sun, the weaker the Sun’s gravitational pull is on that planet.
If the distance between two planets doubles, the gravitational pull they exert on each other will double.
Planets in closer proximity to the Sun will have shorter orbital periods compared to those farther away.
Use the information below to answer the question: Which student’s interpretation is more accurate?

Both students are correct.
Neither student is correct.
Use the information below to answer the question: Which explanation best supports your choice?
The gravitational pull from the planet acts as a brake on the spacecraft, decreasing its speed as it approaches.
The gravitational pull of the planet is used to change the spacecraft's path without affecting its speed.
As the spacecraft gets closer to the planet, the planet’s gravitational pull increases its velocity.
Gravity assists are used to decrease the spacecraft's speed so it can maneuver towards the new target more effectively.
If a new planet were discovered with three times the mass of Earth but in the same orbital position, how would its gravitational interaction with the Sun be different from Earth’s?
The gravitational force would be three times stronger.
The gravitational force would be the same.
The gravitational force would be three times weaker.
The gravitational force would be nine times stronger.
Why does the Moon not crash into Earth? Use scientific reasoning to support your answer.
Because the Moon is too far away from Earth.
Because the Moon is in a stable orbit due to Earth's gravitational pull and its own velocity.
Because the Moon is moving away from Earth at a constant speed.
Because the Moon is held in place by the Sun's gravity.
