  1. 6. A person who travels to space. Astronauts undergo rigorous training and wear special suits to survive in the harsh conditions of space.
  2. 7. A small particle from space that enters Earth's atmosphere and burns up, creating a streak of light known as a shooting star.
  3. 9. A celestial object composed of ice, dust, and gas that orbits the Sun. Comets often have a glowing tail and can be seen in the night sky for a limited period.
  4. 10. An optical instrument used to observe distant objects in space. Telescopes can reveal details of planets, stars, galaxies, and other celestial phenomena.
  5. 12. The force that pulls objects toward each other. Gravity keeps planets in orbit around the Sun and gives weight to objects on Earth.
  6. 13. An astronomical event in which one celestial body obscures another. Solar eclipses occur when the Moon blocks the Sun, and lunar eclipses occur when Earth's shadow falls on the Moon.
  7. 15. A powerful explosion that occurs at the end of a star's life. Supernovae release an enormous amount of energy and can briefly outshine an entire galaxy.

  1. 1. A large celestial body that orbits around a star. Planets are spherical in shape and can be made of rock, gas, or a combination of both. Earth is one of the planets in our solar system.
  2. 2. The natural satellite of Earth. It orbits around our planet and can be seen at night. It appears as a bright, round object in the sky.
  3. 3. A rocky object that orbits the Sun and is smaller than a planet. Asteroids are found in the asteroid belt between Mars and Jupiter.
  4. 4. A luminous celestial body that appears as a tiny point of light in the night sky. Stars emit their own light and are scattered across the universe.
  5. 5. A vehicle propelled by rocket engines that carries objects and people into space. Rockets provide the necessary thrust to overcome Earth's gravity.
  6. 7. A meteor that survives its passage through Earth's atmosphere and lands on the surface. Meteorites can provide valuable information about the composition of space.
  7. 8. A massive collection of stars, gas, dust, and other celestial objects held together by gravity. The Milky Way is the galaxy in which our solar system resides.
  8. 11. The path followed by an object as it revolves around another object in space. Planets, moons, and satellites all have their own orbits.
  9. 14. The star at the center of our solar system. It provides heat and light to Earth and is responsible for day and night.
