Yes, they most certainly can.A few years ago, a large comet crashed into Jupiter, releasing a tremendous amount of energy.
It depends where and how big they are. It could be any of "planet", "minor planet", "moon", "asteroid", "comet", "plutino", "cubewano", or several other even more technical terms.
Any cosmic object (star, planet, meteorit, comet) has a chemical composition.
The universe is a big place, and there's any number of places a comet we've lost site of could go. It could fly off in to a distant reach of space, it could impact a planet or asteroid, or it could even fly in to a sun and burn up.
some scientist have an answer they say that Pluto is not an planet but a comet also they say there are eleven planets
Same as any other comet: away from the Sun.Same as any other comet: away from the Sun.Same as any other comet: away from the Sun.Same as any other comet: away from the Sun.
g comet
It's too cold, it's poison gas giant planet, with a gravitational pull strong enough to crush any Earthlings that tried to live there.
As far as is known, there is no life anywhere, on any planet, satellite, asteroid, meteoroid, comet, star, quasar, nebula, constellation, asterism, space probe, UFO, interstellar cloud, or field of any kind, except for the Earth and the International Space Station.
No. Halley's comet does not pose any threat or Earth.
Any of them because there is no set size for any of them. All of them are classified by different things and none of them are size. A moon orbits a planet, a planet orbits a star in a slightly elliptical orbit, a comet orbits a star in a highly elliptical orbit, and an asteroid is a planet or moon (any celestial object really) that is out of orbit and is flying through the universe a high speeds. For instance, a moon can be bigger than a planet.
Because the gas giants have enormous atmospheres and what we see is the top of the dense cloudy atmosphere, which people cannot stand on. Beneath that the rock surface is so deep down that the atmospheric pressure would crush any machine.
Are you asking how big the crater would be if it struck the Earth? In one sense, it would depend on the size of the comet and the speed; in another sense, it might not matter at all. The kinetic energy of any object is the mass times the velocity squared. Calculate the approximate mass of the comet, multiply it by the collision speed. If the comet were to come from behind, the impact velocity would be lower than if the comet hit us "head on". Whatever the comet's velocity, you would need to add the Earth's escape velocity; any object falling to Earth from space will have a additional velocity from Earth's gravity, which is 7 miles per second, about 25,000 miles per hour. Here's why it really wouldn't matter; if the comet is big enough and fast enough, it won't create a crater; it will re-make the Earth itself. The comet could punch THROUGH the crust of the planet, releasing the magma, the liquid rock in the mantle. If it's big enough, it could wipe out humanity, and many other species on Earth.
