The Sun & Moon
This is the center of our solar system and provides Earth with heat and light.
What is the Sun?
Earth does this on its axis every 24 hours, causing day and night.
What is rotate?
Known as the "Red Planet," this is the 4th planet from the Sun.
What is Mars?
This is the largest planet in our solar system.
What is Jupiter?
This is the third planet from the Sun (Hint: You’re standing on it!).
What is Earth?
Unlike the Sun, the Moon does not make its own light. It does this to the Sun's light instead.
What is reflect?
This is the imaginary line that runs through Earth from pole to pole.
What is an axis?
This planet is often called Earth’s "sister planet" because they are almost the same size. However, it is covered in thick, poisonous clouds that trap so much heat it can melt lead!
What is Venus?
This planet is famous for its very bright, wide rings made of ice and dust.
What is Saturn?
This planet is often called Earth’s "twin" because it is a similar size, but it is much hotter.
What is Venus?
This is the approximate number of days it takes for the Moon to orbit the Earth one time.
What is about 1 month?
This is the name for the nearly circular path Earth takes as it travels around the Sun once every 365 days.
What is orbit?
These four planets are called "terrestrial" because they are mostly made of this material.
What is rock?
These four planets are not rocky; instead, they are known by this "gaseous" nickname.
What are the Gas Giants?
This is the correct order of the planets starting from the Sun.
What are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune?
If you were to compare the sizes of the Earth and the Moon, you could fit about four Moons across the width of one Earth. Looking at the Sun, however, it is much, much larger. Approximately how many Earths could fit inside the Sun?
A) 10
B) 100
C) Over 1,000,000 (1 Million)
C) Over 1,000,000 (1 Million)
This imaginary line runs through the center of the Earth from the North Pole to the South Pole, and Earth tilts on it.
What is an axis?
This inner planet has almost no atmosphere, which means it has no protection from space rocks. Because of this, its surface is covered in thousands of craters, making it look a lot like our Moon.
What is Mercury?
It takes Earth 365 days to orbit the Sun. Does it take a planet like Neptune a shorter time or a longer time to orbit the Sun?
A much longer time.
Even though Mercury is the closest planet to the Sun, Venus is actually the hottest planet in our solar system. Explain why Venus is hotter than Mercury.
Venus has a thick atmosphere (clouds) that traps heat like a blanket.
