By Mrs. Hernandez

Let's Review

•Our solar system is one of millions of solar systems in our galaxy, the Milky Way

•Objects in our solar system are held in place by gravity with the only star, the Sun, in the center

•Stars are different

•Some are smaller, some are larger, and some appear brighter than others; all except the Sun are so far away that they look like points of light

Multiple Choice

Earth’s galaxy contains billions of stars. Some stars appear brighter than others. Which of the following is the main reason that the Sun appears brighter from Earth than other stars in the galaxy?

• a.       Our Sun is a young star.

• b.       Our Sun is closer to Earth.

• c.       Our Sun is a much larger star.

• d.       Our Sun is burning hydrogen.

Multiple Choice

The universe consists of many galaxies. Which choice correctly identifies our home galaxy and its type?

• a.       Abell—elliptical

• b.       Milky Way—spiral

• c.       Andromeda—irregular

• d.       Sculptor—barred spiral

Multiple Choice

Joaquin tells his science class that galaxies consist of gas, dust, and many planets. What is the most important component of galaxies Joaquin is missing in his description?

• a.       asteroids

• b.       comets

• c.       constellations

• d.       stars

Let's Review

The solar system consists of the sun, the planets and their moons, asteroids, meteoroids, thousands of comets, and particles of dust and gas that revolve around the sun

Each of the eight planets spins around an imaginary axis through its center, while also traveling in a clockwise direction around the sun

 

Mercury & Venus have no moons

Earth has one moon

Mars has 2 moons

Jupiter has 69 moons 

Saturn has 62 moons

Uranus has 27 moons

Neptune has 14 moons

​

Multiple Choice

1.       Like many other space objects, Earth travels in a predictable path through space. Which of the following correctly describes this path?

a.       traveling around the Moon in a cycle that repeats every month

b.       orbiting the Sun along with seven other planets in the Solar System *

c.       traveling in the same direction as comets, which is away from the Sun

d.       moving along with asteroids in an asteroid belt between Mars and Jupiter

• a.       traveling around the Moon in a cycle that repeats every month

• b.       orbiting the Sun along with seven other planets in the Solar System

• c.       traveling in the same direction as comets, which is away from the Sun

• d.       moving along with asteroids in an asteroid belt between Mars and Jupiter

Multiple Choice

While both comets and asteroids are found to orbit the Sun in our Solar System, which choice correctly explains how they are different?

• a.       Comets are much larger than asteroids.

• b.       Asteroids form a tail, and comets do not.

• c.       Asteroids have long orbits around the Sun. Comets orbit between Mars and Jupiter.

• d.       Comets are made of ice, dust, and rocky material. Asteroids are made of rock and metal material.
