What impact does size have on objects' gravity?
The larger the mass of an object, the less gravity it has.
Smaller objects have more gravity.
Mass and gravity do not impact.
The larger the mass of an object, the more gravity it has.
What 2 things impact how much gravity is exerted on an object?
Mass
Color
Magnetism
Distance
What are the 3 types of galaxies?
Spiral
Elliptical
Nebula
Irregular
Why are large moons not considered planets?
Because they don’t orbit the Sun, they orbit a planet.
Because they don't have enough mass.
Because they don't create enough gravity.
Because they are too far away.
What are the order of the 4 inner planets?
Mars, Mercury, Venus, Earth
Mercury, Venus, Earth, Mars
Earth, Mars, Mercury, Venus
Venus, Mercury, Earth, Mars
How does mass impact gravity?
Objects with less mass have more gravitational pull
Objects with more mass have more gravitational pull.
Mass has no impact on gravity.
Gravity is constant and never changes.
Which describes a characteristic that is shared by different galaxies in the universe?
They all are about the same distance from the Milky Way.
They all have similar planets and stars.
They all formed because of gravity.
They all have the same shape.
James has created the diagram shown to model three planets in the order of their gravitational force with the Sun. Which change to the model will make it more accurate and why?
reorder the planets to Mercury, Earth, Jupiter, because the Sun pulls more strongly on smaller planets than on larger planets
reorder the planets to Mercury, Earth, Jupiter, because both distance from the Sun and the planets’ masses influence gravitational pull
keep the same order but move Earth and Mercury much farther away, because gravitational pull increases as distance from the Sun increases
put all three planets the same distance from the Sun, because the Sun’s constant mass causes the same gravitational pull on all three planets
Which is NOT part of our solar system?
the moons around Jupiter
asteroids and meteoroids
comets
stars that are not the Sun
The Moon orbits around the Sun.
True
False
Naa is reading an article about objects in the solar system. She finds out that Ganymede, one of Jupiter's moons, is bigger than the planet Mercury. Which statement explains why Ganymede is not classified as a planet?
It orbits Jupiter and not the Sun.
It is not as close to the Sun as Mercury.
It is not shaped like the rest of the planets.
It is held in its orbit by gravity.
Thom reads an article on the internet that that claims some lakes on Saturn are contain frozen methane. He reads that there is methane on Neptune, too. Which sentence best describes data that would suggest methane is frozen on Neptune?
Neptune's atmosphere has more methane than Saturn's.
Neptune's mass is less than Saturn's.
Neptune's surface temperature is colder than Saturn's.
Neptune's distance from the Sun is greater than Saturn's.
Which does NOT have an effect on how strongly the Sun pulls on an object in space?
the mass of the object
how far the object is away from the Sun
the fact that the Sun is made of a mixture of gases
the mass of the Sun
A galaxy that has a shape similar to a football is a(n) _____ galaxy.
normal spiral
barred spiral
elliptical
irregular
Which of the following is defined as a huge collection of gas, dust, and stars held together by gravity?
nebula
solar system
galaxy
universe
Which of the following data can help someone to infer the size of a planet?
how many moons it can capture due to its pull of gravity
how far it is from the Sun in km
its surface temperature in degrees
its surface geography
An asteroid belt found between which 2 planets?
Mars and Jupiter
Earth and Mars
Jupiter and Saturn
Venus and Mars
The illustration shows the path of Earth's orbit around the Sun. Describe the path of Earth if the Sun's gravity were to suddenly stop.
Earth would continue to move within its orbit.
Earth would move in a straight line towards the Sun.
Earth would move in a straight line instead of a curved line.
Earth would stop moving and become suspended in one spot.
NASA has been sending exploration missions to Mars for almost 50 years. The length of time it has taken the different spacecraft to reach Mars ranges from 150 days to 360 days. In order to make it possible for humans to travel to Mars, the travel time must be reduced. Assume the different spacecraft were using the same amount of fuel at the same rate. Why are there such long differences in travel time?
The distance of Mars from the Sun changes
The distance from Earth to Mars changes
The position of Earth from the Sun changes
The shape of the planet's orbit changes
The chart shows the surface temperatures of the outer planets. What can you conclude about the outer planets based on the data table?
If Neptune were closer to the Sun, it would be cooler
Saturn is closer to the Sun than any of the other outer planets
The coldest planet is Uranus
The surface temperature of Earth is between that of Neptune and Jupiter
Which planet has no atmosphere at all?
Mercury
Venus
Mars
Neptune
