It's a question. A present simple question.
No. By defintion a superstition does not have any scientific basis.
No. The light we see from comets is reflected sunlight. Comets are composed of ice and dust, and do not give off any radiation, visible or otherwise. Because of their high ice content, and the water vapor they trail as they travel toward the sun, they are highly reflective.
That description could fit any number of bodies in the solar system, but generally "asteroid" might be closest. Other more distant objects such as comets or Kuiper Belt Objects would tend to be more icy than rocky.
In prehistoric times large objects have caused big craters. Whether before impact these would have appeared like comets is a matter for debate. A comet is a celestial body. Anything that enters the earths atmosphere and/or strikes the earth is deemed a meteorite
All of them , including Earth. !!!! Because the local environment of each planet is so different from Earth, we , humans, cannot survive on them. I include Earth, because people can be killed by geophysical activity , earthquakes, etc., also being bombarded by asteroids/comets.
You just did, but I question your intentions.Was that a question?Don't ask me another question!Will that question be on the test?
There are no comets that orbit the planet Mars. Comets, some, orbit the sun. Mars on the other hand does have two moons, Phobos and Deimos.
Yes, there are many comets other than Halley's comet. Comets are icy bodies that orbit the Sun and often have elongated orbits that bring them close to the Sun. Some well-known comets include Hale-Bopp, Comet NEOWISE, and Comet Lovejoy.
There are no visible comets at this time.
NO
"I'm not in the mood to answer any more questions today."
Comets contain various types of ice (water and also other frozen liquids or gases) which sublime to vapor when the comet approaches the inner solar system.
Any object will attract any other object - the comets of the Oort Cloud will attract each other and other objects; also, the gravity of the Sun will still be active at the Oort Cloud.
The correct question would be "Why don't any of you know the answer to any of my questions?" And the answer would be because there are about 50,000,000 other questions that could be more important.
Just like any other sentence..!!
yes, they have discovered plenty
A sentence with the word 'porcupine' in it is no different from any other sentence, it is just a sentence referring to a porcupine.
