Across
- 3. The force of attraction between objects. Gravity keeps planets in orbit around the sun and holds objects on the surface of a planet.
- 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.
- 9. Station A large spacecraft where astronauts live and work for extended periods. Space stations provide a base for scientific research and space exploration.
- 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.
- 12. A person who is trained to travel and work in space. Astronauts conduct scientific experiments and explore outer space.
- 14. The act of traveling and investigating unknown or unfamiliar places. Space exploration involves venturing into outer space to learn about the universe.
- 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.
- 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.
Down
- 1. The vast expanse that contains all matter, energy, and celestial objects. It includes galaxies, stars, planets, and other celestial bodies.
- 2. An object that orbits around a planet or a star. Satellites are used for communication, weather forecasting, and scientific research.
- 4. A vehicle designed for travel or operation in space. Spacecraft can be manned or unmanned and are used for exploration and scientific research.
- 5. An optical instrument that allows us to observe distant objects in space. Telescopes help astronomers study stars, galaxies, and other celestial phenomena.
- 6. A vehicle that is designed to propel itself into space. Rockets are used to launch satellites, spacecraft, and astronauts into orbit.
- 8. A specially designed suit worn by astronauts in space. Spacesuits provide protection from the harsh environment of space.
- 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.
- 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.
