The densities of the planets are about five times the density of water. 3. A planet s ability to retain an atmosphere depends on its and temperature. 4. A cloud of dust and gas in space is called a(n). 5. Planets originally formed when bits of matter collided and clumped together to form. 6. Because of its similarities to Earth, the planet has been called Earth s twin. 7. The Martian polar caps are made of, covered by a thin layer of frozen. 8. Although the atmosphere of is very thin, extensive dust storms with wind speeds in excess of 270 kilometers per hour do occur. 9. With at least 28 moons, the planet and its satellites resemble a miniature solar system. 10. The most prominent feature of is its system of rings. 11. are small rocky bodies that have been likened to flying mountains. 12. The total mass of all asteroids is estimated to be only 1/1000 that of. 13. Label the items pointed out in Figure A meteoroid that reaches Earth s surface is called a(n).
