Across
- 5. An icy chunk of frozen gases, water, and dust that continually orbits the sun
- 12. A complete orbit of a planet around the sun or of a moon around a planet
- 14. An eclipse in which the moon passes between the sun and the earth
- 16. our closest star
- 18. A complete spin of a planet or moon on its axis
- 20. tens to hundreds of times larger and hundreds of times more luminous than the sun
- 21. A cloud of interstellar gases and debris
- 22. An unmanned research spacecraft sent beyond Earth’s orbit
- 25. A rocky object in space that is smaller than an asteroid
- 26. Stars that regularly or repeatedly change in magnitude
- 29. small- and medium-sized stars
- 31. hundreds of times larger than the sun and thousands of times brighter
- 33. A telescope that uses only lenses to make objects appear larger
- 35. A bright cloud of gas on the sun’s surface; usually accompanies sunspots
- 36. A group of stars that appear to form a picture or pattern in the sky
- 38. the distance that light travels in one year
- 39. A meteor that does not burn up in Earth’s atmosphere and hits Earth’s surface
- 40. stars go through periods of swelling and brightening, then shrinking and dimming
Down
- 1. brightness of a star
- 2. An object that orbits the sun and that has enough gravity to be spherical but not enough gravity to have an orbit clear of other objects of simi
- 3. A meteoroid that lights up because of friction as it moves through Earth’s atmosphere
- 4. Irregularly shaped pieces of rock, metal, and dust that orbit the sun
- 6. does not change its absolute magnitude but does change its apparent magnitude
- 7. Any object that orbits another object in space
- 8. he death explosion of a massive star
- 9. a true brightness of a star
- 10. An area of extreme gravitational force that may result from the collapse of a massive supergiant star
- 11. A small star group of three or four stars
- 13. An eclipse caused when the earth blocks part or all of the sunlight that is usually reflected by the moon; occurs when the moon passes through Earth’s shadow
- 15. he death explosion of a massive star
- 17. The event that occurs when a celestial body completely eclipses another celestial body
- 19. A star group containing two stars that revolve around each other
- 23. A telescope that uses lenses and mirrors to make objects appear larger
- 24. A device that breaks down light into all its colors; similar to a prism
- 27. The scientific study of the stars and heavenly objects
- 28. A term describing the rocky, dense, and Earthlike planets that are closest to the sun
- 30. what the brightness of the star appears to the human eye
- 32. Energy emitted in colors of light near Earth’s poles, caused by solar wind and Earth’s magnetic field
- 34. Any of the outer planets, Jupiter, Saturn, Uranus, and Neptune, which are made mostly of gases
- 37. A large object that orbits the sun and that has enough gravity to be spherical and to have an orbit clear of other objects of similar size other than its moons
- 41. A star that suddenly flares and becomes hundreds or thousands of times brighter than normal
