Across
- 1. A three-dimensional shape or object that is round in shape.
- 4. A small, rocky metallic, or icy bodies with no atmosphere that orbit around the Sun.
- 5. The sixth planet from the Sun and the second largest in the Solar System, after Jupiter.
- 8. The third planet from the Sun and the only astronomical object known to harbour life.
- 9. Their immense distances from Earth make them appear as fixed points of light.
- 10. The Moon passes between the Earth and the Sun, blocking the Sun’s light either partially or completely for observers on Earth.
- 12. A large system of stars, gas, dust and dark matter bound together by gravity.
- 15. The Earth moves between the Sun and the Moon, causing the Earth’s shadow to cover the Moon.
- 18. The phase of the moon at which the moon, as viewed from Earth, does not appear to be illuminated by the sun. At this phase, the lunar disk is not visible to the naked eye, except when it is silhouetted against the Sun during a solar eclipse.
- 19. The curved trajectory of an object such as the trajectory of a planet around a star.
- 21. The planet second-closest to the Sun in the Solar System
- 22. It starts right after the full moon and lasts until it becomes a Third Quarter Moon.
- 23. The first phase of the Moon’s cycle after the new moon. It appears as a thin, crescent-shaped sliver of light in the sky.
- 24. The Sun and eight planets, moons, asteroid, and comets, that orbit the Sun.
- 25. The phase of the moon at which the moon appears to be fully illuminated by the sun.
- 26. The eighth and farthest known planet orbiting the Sun.
- 27. Smallest and closest planet to the sun in the Solar System.
Down
- 1. The expanse in which the solar system, stars, and galaxies exist.
- 2. The moon moves through its eight phases, as it obits the Earth.
- 3. The irregular luminous band of stars and gas clouds that stretches across the sky as seen from Earth. A faint band of light that looks like milk spilled across the sky.
- 6. The fourth planet from the Sun. It is also known as the "Red Planet".
- 7. Cosmic body of extremely intense gravity from which nothing, not even light can escape.
- 11. It starts after the First Quarter Moon and lasts until the Full Moon.
- 13. The planet's atmosphere has a complex layered cloud structure and has the lowest minimum temperature of all the Solar System's planets.
- 14. The fifth planet from the Sun and the largest in the Solar System.
- 16. It is by far the most important source of energy for life on Earth.
- 17. The final phase before the new moon.
- 20. The science of finding a way from one place to another.
