Describe the orbital path of most planets in our solar system?
Which of the following represents characteristics of the four planets farthest from the Sun?
Smaller planets

The Sun is the center of our solar system and creates a large amount of gravitational force. If this system lost the Sun, what would happen to the planets?
The planets would explode.
The planets would stop moving.
The planets would travel on a different path.
The planets would continue on their same path.
How is it depending on the size, mass, and density of an object, the gravitational force it exerts varies? Explain short.
Which statement typically demonstrates the relationship between the mass of a celestial body and its gravitational pull?
Mercury has the least mass of the planets in the solar system, so it has the greatest gravitational pull.
Venus has less mass than Earth, so Earth has a lesser gravitational pull.
Jupiter has the greatest mass of the planets in the solar system, so it has the greatest gravitational pull.
The mass of a celestial body is not related to its gravitational pull on other bodies.
All of the following are ways that the atmosphere makes the existence of life on earth possible EXCEPT —
