Across
- 2. A large group of stars, dust, gas and dark matter held together by gravity
- 4. Small solar system bodies that orbit the Sun. Made of rock, metal, and organic compounds. Do not have a visible coma (fuzzy outline and tail)
- 6. A natural satellite which orbits the Earth. It is around a quarter the size of Earth and can be easily seen in the night sky
- 7. The second closest planet to the Sun. It is similar in size to Earth and features thick a thick atmosphere which locks in heat as the surface rages with active volcanoes
- 9. Meteoroid that burns up as it passes through the Earth’s atmosphere
- 12. The eighth planet from the Sun and is nearly four times the size of Earth. It features strong winds and violent weather.
- 13. A star and the biggest object in the Solar System, it burns brightly in the center as planets and other objects orbit around it.
- 14. Was the furthest planet from the Sun until it was demoted from a planet to a dwarf planet in 2006
- 15. The second largest planet in our solar system, the sixth planet from the Sun and features an impressive system of rings.
- 16. way A spiral galaxy where our Solar System and Earth are located
Down
- 1. The largest planet in our solar system. It features the famous ‘Red Spot’ and a large number of orbiting moons.
- 3. Someone trained to be a crew member of a spacecraft
- 5. A relatively small solar system body that orbits the sun.When close enough to the Sun they display a visible coma (a fuzzy outline or atmosphere due to solar radiation) and sometimes a tail
- 8. The third largest planet in the Solar System and seventh planet from the Sun. It rolls like a barrel rather than spinning like Earth and was the first planet discovered by telescope.
- 10. The fifth largest planet in the Solar System and third from the Sun
- 11. The closest planet to the Sun in the Solar System. As well as being very hot, it features a barren, crater covered surface which looks similar to the Moon
- 16. The 'Red Planet' as it is sometimes known, is the fourth planet from the Sun. It features a dusty, rocky surface, relatively calm conditions and a thin atmosphere
