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.]
They live near the sun and are in the solar system,
both orbit the sun!(:
They all orbit the Sun.
hu people
They all orbit around the sun.
i din't think so but sometimes comets are
The earth has several possible threats from outer space. Some of those threats are comets, asteroids, and large solar flares.
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.
Planets, exoplanets, asteroids. They're all sattelites of the sun.
Comets are Comets and Asteroids are Asteroids
Asteroids and Comets
There are no known asteroids or comets that have impacted Mercury.
it can destroy earth
Many cultures have superstitious beliefs about comets and asteroids. The Philippines do not seem to share superstitions of comets and asteroids.
Comets!

No. Comets orbit the sun.
Well, some asteroids have small moons, and comets are the size of Earth mountains.
It is possible for comets and asteroids to hit Earth, but they are extremely rare events.
