What's wrong with Han Solo's claim of making "the Kessel Run in less than 12 parsecs"
Even the Millennium Falcon can't travel that fast
He should have used 'astronomical units'
Parsec is a measure of distance, not time
He should have used 'light seconds'
Gustavo is doing a presentation in class comparing the objects of space by their relative sizes.
If “Z” represents a planet, what would “Y” most likely represent?
A solar system because it contains planets and stars.
A nebula because that is what the planets formed from.
A galaxy because it contains billions of stars and the planets.
A universe because it contains billions of stars and the planets.
Which statement below best describes the Universe?
The Universe is a black hole made of dark matter.

The Universe contains the Milky Way galaxy which contains most of the stars in space.
The Universe contains many billions of galaxies and each galaxy contains many billions
of stars.

Joe tells Gabby his theory about why sea turtles nest on the beach instead of in the ocean. He says, “The turtle eggs would sink to the bottom of the ocean, and the baby turtle would drown. I know this because my uncle is a fisherman, and he told me this information. Gabby tells Joe that his theory is not scientific. Why does Joe’s idea not meet the requirements to be a scientific theory?
Joe’s idea is already a scientific law.
Joe’s idea is not supported by scientific evidence.
Joe’s idea is a good guess that can be tested by experiments.
Joe and his uncle are not scientists.

Jamal is making a model of the universe using common objects to represent the universe, the Milky Way, the solar system and the Sun. He chooses a grape, his classroom, a tennis ball and an extra-large pizza to represent objects in his model. He decides to use the pizza to represent the Sun. Why is Jamal’s decision not the best choice?
The grape is the better choice since it is the smallest of the selected objects.
The classroom should be used since it is large like the Sun.
The tennis ball is the better choice due to its yellow color
The pizza is the better choice because of its shape.
The Hubble Space Telescope recently provided scientists with an image and data related to an object in space that is composed of billions of stars of different colors and sizes and enough gas and dust to make billions more stars.
What conclusion can be drawn from this information?
The image is of a distant solar system because of the presence of at least one star.
The image is of galaxy because of the presence of billions of stars, gas and dust.
The image is of the entire universe, because of the presence of stars, gas, and dust
The image is of the formation of a new planet as indicated by the presence of dust.
The astronomical objects should be listed in order from largest and smallest. One group is not. Which group is NOT listed in the correct order?
Group 1: Sun, Jupiter, Earth, Mercury, Moon
Group 2: Milky Way Galaxy, Universe, Solar System, Mars
