Semester Review: Astronomy

Front

What is the gravitational pull of the Sun compared to other objects in the Solar System?

Back

The Sun has the strongest gravitational pull in the Solar System, which keeps the planets, moons, and other objects in orbit around it.

Front

What is a revolution in astronomy?

Back

A revolution is the time it takes for an object to complete one full orbit around another object, such as a planet orbiting the Sun.

Front

What is the difference between rotation and revolution?

Back

Rotation refers to an object spinning on its axis, while revolution refers to an object moving in an orbit around another object.

Front

What are the main components of our Solar System?

Back

The main components are the Sun, planets, moons, asteroids, comets, and meteors.

Front

How do moons and planets differ in their orbits?

Back

Planets orbit around stars, while moons orbit around planets.

Front

What is the average time it takes for the Moon to go from new moon to full moon?

Back

Approximately two weeks.

Front

What is a comet?

Back

A comet is a small celestial body made of ice, dust, and rocky material that, when close to the Sun, develops a glowing coma and tail.

Front

What is a meteor?

Back

A meteor is a small particle from space that burns up upon entering Earth's atmosphere, creating a streak of light.

Front

What is the role of gravity in planetary motion?

Back

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