12. Because there is no atmosphere on the moon, any liquid water would have evaporated into space long ago.

13. The length of a planet’s day is determined by its speed of rotation.

14. The large, irregular objects mostly located between Mars and Jupiter are asteroids.

15. Icy objects that mostly travel in long, elliptical orbits around the sun are comets.

Explanation:

The solar system has 8 planets which revolve about sun in elliptical orbits.

All the planets other than Mercury and Venus have natural satellites revolving about them. Earth has 1 moon. Mars has two moons - Phobos and Deimos.  Jovian planets have many moons.        

Moons don't have atmosphere because of their low gravity due to which water would have evaporated even it would have been present.            

The speed of rotation determines the duration of day on a planet. 1 day on Earth = 24 hours. 1 day on Mercury = 58.646 Earth days.

Asteroids are large irregular rocky bodies which orbit sun. Majority of these bodies lie in asteroid belt in between the orbits of Mars and Jupiter.

Comets are icy bodies found in Kuiper belt and Oort cloud. These travel around the sun in long elliptical orbit. Comets are composed rock, dust, ice and frozen gases.
