BIG BANG PROJECT
Across
- 1. the natural satellite of the earth, visible (chiefly at night) by reflected light from the sun:
- 4. the planet on which we live; the world:
- 5. the largest planet in the solar system, a gas giant which is the fifth in order from the sun and one of the brightest objects in the night sky.
- 8. a distant planet of the solar system, seventh in order from the sun, discovered by William Herschel in 1781.
- 9. a fixed luminous point in the night sky which is a large, remote incandescent body like the sun.
- 12. a small planet that is the closest to the sun in the solar system, sometimes visible to the naked eye just after sunset.
- 13. hole a region of space having a gravitational field so intense that no matter or radiation can escape.
- 14. a small, rapidly moving meteor burning up on entering the earth's atmosphere.
Down
- 2. a distant planet of the solar system, eighth in order from the sun, discovered in 1846.
- 3. the second planet from the sun in the solar system, the brightest celestial object after the sun and moon and frequently appearing in the twilight sky as the evening or morning star.
- 6. a small planetary body orbiting the sun, discovered in 1930 by Clyde Tombaugh.
- 7. a system of millions or billions of stars, together with gas and dust, held together by gravitational attraction.
- 10. the star around which the earth orbits:
- 11. the sixth planet from the sun in the solar system, circled by a system of broad flat rings.
- 12. a small reddish planet which is the fourth in order from the sun and is periodically visible to the naked eye
