  1. 3. The force of attraction between objects. Gravity keeps planets in orbit around the sun and holds objects on the surface of a planet.
  2. 7. A celestial body that orbits around a star and is large enough to have its own gravity. Earth is a planet that supports life.
  3. 9. Station A large spacecraft where astronauts live and work for extended periods. Space stations provide a base for scientific research and space exploration.
  4. 11. System A system of planets, moons, asteroids, and other celestial objects that orbit around a star, known as the Sun. Our solar system includes eight planets.
  5. 12. A person who is trained to travel and work in space. Astronauts conduct scientific experiments and explore outer space.
  6. 14. The act of traveling and investigating unknown or unfamiliar places. Space exploration involves venturing into outer space to learn about the universe.
  7. 15. A large system of stars, gas, and dust held together by gravity. Our Milky Way galaxy is home to billions of stars and planets.
  8. 16. The path followed by an object as it revolves around another object. Satellites and planets orbit around a central body due to gravitational forces.

  1. 1. The vast expanse that contains all matter, energy, and celestial objects. It includes galaxies, stars, planets, and other celestial bodies.
  2. 2. An object that orbits around a planet or a star. Satellites are used for communication, weather forecasting, and scientific research.
  3. 4. A vehicle designed for travel or operation in space. Spacecraft can be manned or unmanned and are used for exploration and scientific research.
  4. 5. An optical instrument that allows us to observe distant objects in space. Telescopes help astronomers study stars, galaxies, and other celestial phenomena.
  5. 6. A vehicle that is designed to propel itself into space. Rockets are used to launch satellites, spacecraft, and astronauts into orbit.
  6. 8. A specially designed suit worn by astronauts in space. Spacesuits provide protection from the harsh environment of space.
  7. 10. A natural satellite that orbits around a planet. Earth's moon is our closest neighbor in space and affects tides and other phenomena on Earth.
  8. 13. A luminous celestial body made up of hot gases that emit light and heat. The Sun is a star that provides heat and light to our planet.
