They all orbit around the sun.

∙ 9y agoComets and asteroids are similar in that they are both parts of the solar system left over after formation. They both orbit the sun. They have irregular shapes because they are not massive enough to form circles like planets. They spin strangely because of their shapes. They frequently crash into Earth.

∙ 10y agoThey are alike because they both orbit the Sun.
They both usually contain rocky material. In comets the material is
not so compacted and is often called "dust".

Are asteroids surrounded by a hydrogen cloud?
i din't think so but sometimes comets are
In what ways are comets and asteroids similar?
Asteroids and comets have a few things in common. They are both celestial bodies orbiting our Sun, and they both can have unusual orbits, sometimes straying close to Earth or the other planets. They are both "leftovers" - made from materials from the formation of our Solar System 4.5 billion years ago. While asteroids consist of metals and rocky material, comets are made up of ice, dust, rocky materials and organic compounds. When comets get closer to the Sun, they lose material with each orbit because some of their ice melts and vaporizes. Asteroids typically remain solid, even when near the Sun. When comets approach the Sun, some of their ices melt. This causes another notable difference between asteroids and comets: comets have "tails" while asteroids generally don't. When the ices in comets begin to melt and other materials vaporize from the heat from the Sun, this forms a glowing halo that extends outward from the comet as it sails through space. There is a big difference when it comes to numbers… although there is a caveat in that we don't know precisely how many asteroids OR comets there are in our Solar System, since lots have never been seen. Astronomers have discovered millions of asteroids - some as small as dust particles and others measuring hundreds of kilometers across (width). But as of this writing, astronomers have found only about 4,000 comets. [However, some estimates say there could be one hundred billion comets in the Oort cloud.]
Whats threats are there to earth from outer space?
The earth has several possible threats from outer space. Some of those threats are comets, asteroids, and large solar flares.
What space objects are made of chunks of rock?
Comets and asteroids are made of chunks of space rocks and dust. Meteorites are space rocks that are captured by the earth's gravity and fall to earth.
Objects that orbit the sun?
Planets, exoplanets, asteroids. They're all sattelites of the sun.
What do comets and asteroids not have in common?
Comets are Comets and Asteroids are Asteroids

Well, some asteroids have small moons, and comets are the size of Earth mountains.
