Answer:
<em>They orbit the Sun.</em>
<em></em>
Explanation:
Asteroids are small planetary bodies, too small to be classified as a planet. Asteroids are made up of rocky materials, and they orbit the sun. In our solar system, a vast number of asteroids exists together in the 'great asteroid belt' a region between the orbit of Mars and Jupiter. A comet is a ball of frozen gas, rocks and dusts, that travels around the sun in the solar system. Comets can be as big as a small town. When the orbit of a comet brings it close to the sun, it melts, leaving a trail of gas behind it. This trail of gas is the characteristic long tail of a wishing star seen in the sky in some clear night.
<em>The common property of a comet and an asteroid is that they both travel around the sun in the solar system, just like every other planetary body in the solar system.</em>
