What is the difference between a meteoroid and a meteor?

• A meteoroid is a small rock or particle from space, while a meteor is the streak of light produced when a meteoroid enters the Earth's atmosphere.

• A meteoroid is a large celestial body, while a meteor is a small fragment of a comet.

• A meteoroid is a type of star, while a meteor is a planet.

• A meteoroid is a cloud of gas, while a meteor is a solid object.

What is a dwarf planet?

• A celestial body that orbits the sun and is similar to a planet but does not clear its orbit of other debris.

• A large asteroid that has a stable orbit around the sun.

• A type of star that is smaller than a regular star.

• A moon that orbits a planet and has a solid surface.

What is an asteroid?

• A small rocky body that orbits the sun, primarily found in the asteroid belt between Mars and Jupiter.

What are gas giant planets?

• Large planets composed mostly of gases like hydrogen and helium, with a small rocky core.

• Small, rocky planets that are similar to Earth.

• Planets that are primarily made of ice and have a solid surface.

• Planets that are mostly composed of metals and have no atmosphere.

What is the Kuiper Belt?

• A region of the solar system beyond Neptune that contains many small icy bodies, including dwarf planets like Pluto.

• A belt of asteroids located between Mars and Jupiter.

What is the role of gravity in the solar system?

• Gravity is the force that keeps planets in orbit around the sun and moons in orbit around planets.

• Gravity is responsible for the color of the planets.

• Gravity only affects the Earth and its moon.

• Gravity is a force that pushes planets away from the sun.

What is a comet?

• A large rock that orbits the Earth.

• A ball of ice and dust with a tail of gas and dust pointing away from the sun.
