Solar System Part 1

Which pair of objects will experience the strongest gravitational force?

• Two light objects far apart

• Two heavy objects far apart

• Two light objects close together

• Two heavy objects close together

A student is comparing the planet Mars with Earth. They learn that the force of gravity an object experiences on Mars is less than the force of gravity experienced on Earth. Which statement BEST describes why objects on Mars experience less gravity than Earth?

• Mars is closer to the Sun than Earth.

• Mars is farther from the Sun than Earth.

• The mass of Mars is less than the mass of Earth.

• The mass of Mars is greater than the mass of Earth.

Based on the drawing and the table in the passage, which statement correctly describes the relationship between the distances of stars from Earth and their appearances?

• The size and brightness of a star appear to increase at a greater distance from Earth.

• The size and brightness of a star appear to decrease at a greater distance from Earth.

• The size of a star appears to decrease at a greater distance from Earth; the brightness of the star appears unchanged.

• The size of a star appears to increase at a greater distance from Earth; the brightness of the star appears unchanged.

Four stars in another part of the night sky are shown. Which two statements correctly compare the distances of these stars from Earth?

• Star 1 is the closest star to Earth.

• Star 3 is the closest star to Earth.

• Star 3 is farther from Earth than star 4.

• Star 3 is farther from Earth than star 2.

The table provides information about several galaxies and their shapes: Sagittarius Dwarf Elliptical — Elliptical; Canis Major Dwarf — Irregular; Hoag's Object — Ring; Milky Way — Disc. In what type of galaxy is the Sun located?

• an elliptical galaxy

• an irregular galaxy

• a ring-shaped galaxy

• a disc-shaped galaxy

A student is making a model of the Milky Way. What should the student include the MOST of in their model?

• stars

• comets

• galaxies

• asteroids

Which of the objects in Earth's solar system is the largest?

• the Sun

• a comet

• the Moon

• an asteroid

Reorder the following from largest to smallest.

• Universe

• Galaxy

• solar system

• earth

• All planets are kept in orbit because of the ​ (a)   .
