No. It is over 55 million miles from Earth when it gets to its closest so there is no chance of it hitting us.
A Comet is a body in perpetual orbit. A Meteorite is a body which enters the Earth's atmosphere. It is unlikely that Halley's Comet will ever crash into the Earth.
We don't know exactly. The person who recognized that it was the same comet appearing periodically every 76 years or so was Edmund Halley, but we don't know who was the first to ever see it.
No
As far as is known from written records in human history,no comet has ever circled the earth.
Halley's Comet is unlikely to ever pose a hazard to the Earth. As such, it has no ecological significance.
Theoretically it is possible, but the odds are realy against it.
Probably several times. It is assumed that a third of Earth water came from comets and it was a comet that hit the Earth 65 million years ago and caused the dinosaur extinction.
Halley's Comet is unique because it is one of the most famous comets known to humanity due to its regular appearance every 75-76 years. It is also the only short-period comet that is visible to the naked eye from Earth and has been recorded by humans for over 2,000 years. Additionally, Halley's Comet contains a nucleus made of ice, dust, and rocky material that gradually vaporizes as it gets closer to the Sun, creating its iconic glowing tail.
Halley's Comet
"Periodic" comets reappear at predictable intervals, such as Haley's Comet. Some comets are never seen again. A few crash into the Sun and are destroyed; a few crash into other planets, such as the Shoemaker-Levy comet that hit Jupiter. Many comets have such long periods, in terms of thousands of years, that no records exist that anyone ever saw them before.
as far as i am aware it is haley's comet
No. At its closest it is over 55 million miles from Earth, so it cannot harm anyone.
