Celestial Bodies

Evelyn, Charlotte, and Ethan are studying astronomy. They are curious to know what is the primary source of light and heat for planets in our solar system. Can you help them?

• The Moon

• Betelgeuse

• Stars

• Dwarf planets

During a school astronomy project, Jackson, Aria, and Daniel were tasked to create a model of the solar system. They needed to identify which planet is the smallest, with a diameter just slightly larger than Earth's moon. Which planet should they choose for their model?

• Jupiter

• Venus

• Mercury

• Mars

During a school astronomy project, Benjamin, Kai, and Zoe are discussing celestial bodies. They wonder, what are natural satellites commonly known as?

• Asteroids

• Moons

• Comets

• Dwarf planets

In a classroom science project, Aiden, Anika, and David are building models of the solar system. They notice that their model of a dwarf planet is unable to clear its orbit of other debris. Why is this the case?

• They are too large

• They are too small

• They have irregular orbits

• They lack sufficient gravitational pull

During a school science project, Benjamin, David, and Rohan are building a model of the solar system. They are curious about what asteroids are primarily made of. What should they use to represent asteroids?

• Gaseous materials

• Icy bodies

• Rocky objects

• Pure metal

Anika is working on a school project about the solar system. She needs to identify where the asteroid belt is located. Can you help her?

• Between Earth and Mars

• Between Mars and Jupiter

• Beyond Neptune

• Near the Sun

Imagine Charlotte, Aria, and Michael are observing the night sky when they see an asteroid entering Earth's atmosphere and it survives its journey to the surface. What is it called now?

• It becomes a comet

• It is called a meteorite

• It disintegrates completely

• It returns to space

As Ethan, Harper, and Samuel observe the night sky for their astronomy project, they notice a comet approaching the sun. What characteristic feature does the comet develop?

• A rocky surface

• A glowing tail

• A magnetic field

• An icy crust

During a science fair, Nora presents a model of a black hole. What is unique about black holes according to Nora's presentation?

• They are invisible

• They emit light

• Nothing can escape their gravity, not even light

• They are the smallest objects in the universe

During a school science project, Liam, Priya, and Rohan are discussing the primary role of the International Space Station (ISS). What do they conclude is the main purpose of the ISS?

• To serve as a military outpost

• To facilitate space tourism

• To conduct experiments in microgravity

• To monitor Earth's climate
