  1. 3. A celestial object composed of ice, dust, and gas that orbits the Sun. When a comet gets close to the Sun, it develops a glowing coma and a tail.
  2. 5. A cloud of gas and dust in space, often illuminated by nearby stars or glowing due to the emission of light from hot gases.
  3. 7. An object that orbits around a planet or another celestial body. Artificial satellites are man-made objects used for communication, observation, or scientific research.
  4. 8. A vehicle that is propelled by engines, used for launching spacecraft into space. Rockets generate thrust by expelling exhaust gases at high speeds.
  5. 9. Hole A region in space where gravity is extremely strong, causing anything that enters it to be pulled in with great force. Black holes have such a strong gravitational pull that not even light can escape.
  6. 10. System The system consisting of a star (usually referring to the Sun) and all the celestial bodies that orbit around it, including planets, moons, asteroids, and comets.
  7. 12. A large celestial body that orbits around a star, such as the Earth, Mars, or Jupiter. Planets are usually spherical in shape and do not produce their own light.
  8. 13. The entirety of space, including all matter, energy, galaxies, and other celestial objects. The universe is believed to be vast and ever-expanding.
  9. 15. Relating to the Moon. Lunar refers to anything associated with or happening on the Moon, such as lunar eclipses or lunar landings.
  10. 16. The force that attracts objects toward each other. Gravity is what keeps planets in orbit around the Sun and gives weight to objects on Earth.

  1. 1. A group of stars that form a recognizable pattern or shape. Constellations are often named after mythological figures or objects and can help navigate the night sky.
  2. 2. A massive collection of stars, gas, dust, and other celestial objects bound together by gravity. Our Milky Way is an example of a galaxy.
  3. 4. An optical instrument used for observing distant objects in the sky. Telescopes can magnify and enhance the visibility of stars, planets, and galaxies.
  4. 6. A person who travels and works in space. Astronauts are specially trained to operate spacecraft and perform experiments in microgravity.
  5. 11. A small piece of rock or metal that enters the Earth's atmosphere and burns up due to friction, creating a streak of light in the sky.
  6. 14. A bright point of light in the night sky, often seen as a twinkling object. Stars are massive balls of hot gas that emit their own light.
