Halley's Comet is arguably the most famous comet in history. It is visible from Earth every 76 years, making it a well-known and anticipated astronomical event for centuries. Its appearances have been recorded since ancient times, with the earliest known sighting dating back to 240 BC.
Halley's comet - which returns to our solar system approximately every 75 years - is one example, named after it's discoverer Edmund Halley. Another notable example is Shoemaker-Levy 9. It was observed orbiting the planet Jupiter, but the orbit was decaying - leading to the prediction that it was to crash into Jupiter's surface.
No. in 1961 the comet was way out in the solar system, the recent close approaches were in 1910 and 1986 - non of there were as close as 10 miles from the nucleus, although Earth did pass through the comets tail in 1910.
By themselves, comets are not really important. Even the most impressive comet, like Hale-Bopp, is a visual spectacle only. But the POTENTIAL for a comet - to strike the Earth directly and cause untold devastation - is far more significant. Right now, if we were to see a comet aimed at the Earth, there is very little that we could do about it, other than stand there and die. The threat of a comet impact, like the ones that have devastated our planet several times before, ought to be enough spur us all into looking for ways to protect ourselves from the inevitable time that it WILL happen again.
Yes, it is possible for a comet to be visible from Earth more than once if it has a return orbit. Some comets have orbital periods that bring them back around and make them visible multiple times in a human lifetime.
No because the scaffoldings were invented in the 5th century and the medieval times started at the 5th centuary. Also because it was invented in Eygept not the UK.
Halley's Comet or Comet Halley (officially designated 1P/Halley) is the most famous of theperiodic comets and can currently be seen every 75--76 years. Halley's Comet last appeared in the inner Solar System in 1986, and will next appear in mid-2061.

I'm pretty sure she doesn't. I have just died in a comet mission about twelve times- by now she has usually appeared. It looks like I'm going to have to use skill to pass this level! :)
Halley's Comet was observed and recorded many times in many places around the world. Sir Edmond Halley demonstrated that the repeated sightings were of the same object, the comet that now bears his name.
