Rocks in Space

What are asteroids?

• Asteroids are man-made satellites sent to explore outer space.

• Asteroids are large icy bodies that orbit the Earth.

• Asteroids are small rocky objects that orbit the Sun.

• Asteroids are stars that have fallen from the sky.

How are asteroids different from comets?

• Asteroids are found only in the outer solar system, while comets are found in the inner solar system.

• Asteroids are rocky and metallic, while comets are icy bodies.

• Asteroids are made of gas, while comets are made of rocks.

• Asteroids have tails, while comets do not have tails.

What is the asteroid belt?

• The asteroid belt is a region of space between the orbits of Earth and Venus.

• The asteroid belt is a region of space between the orbits of Mars and Jupiter where many asteroids are found.

• The asteroid belt is a cluster of comets near Saturn.

• The asteroid belt is a ring of debris around Earth's orbit.

How do asteroids orbit the Sun?

• Through magnetic fields interaction

• Due to the gravitational pull between the Sun and the asteroid

• Because they are pushed by solar winds

• By following a predetermined path

What is the composition of most asteroids?

• Plastic and glass

• Diamonds and gold

• Rock and metal

• Ice and gas

How do asteroids pose a potential threat to Earth?

• Due to the possibility of impact, which can result in significant damage, mass extinction events, and disruption of ecosystems.

• Asteroids are easily deflected by Earth's atmosphere

• Asteroids are too small to cause any damage

• Asteroids are harmless space rocks

What is the difference between meteoroids, meteors, and meteorites?

• Meteoroids are on the ground, meteors are on the ground, and meteorites are in space.

• Meteoroids are in space, meteors are in the atmosphere, and meteorites are on the ground.

• Meteoroids are on the ground, meteors are in space, and meteorites are in the atmosphere.

• Meteoroids are in the atmosphere, meteors are in space, and meteorites are on the ground.

What is the role of Jupiter in protecting Earth from asteroid impacts?

• Jupiter's rings act as a shield against asteroid impacts on Earth.

• Jupiter's gravitational pull deflects or captures asteroids that could otherwise collide with Earth.

• Jupiter's magnetic field repels asteroids away from Earth.

• Jupiter's moons absorb asteroid impacts before they reach Earth.

What are Near-Earth Objects (NEOs) and why are they important to study?

• NEOs are fictional objects created for entertainment purposes.

• NEOs are distant stars that have no impact on Earth.

• NEOs are underground minerals that are not relevant to scientific study.

• NEOs are comets and asteroids that have orbits bringing them close to Earth, and studying them is crucial due to their potential impact threat.

How do scientists track and study asteroids that come close to Earth?

• Telescopes, radar systems, and spacecraft are used to observe asteroids' characteristics and movements.

• Using a crystal ball to predict their movements

• Using weather balloons equipped with sensors

• Sending messages to the asteroids
