It takes Halley's Comet 74 to 76 earth years to complete an orbit of the Sun.
It can be influenced by passing the large outer planets, so its revolutions are
not always the same duration.
Halley's Comet is an astronomical body not a terrestrial one. It is made of mainly frozen ices. A tsunami is not possible there.
The Bayeux Tapestry, not Halleys comet, is a famous 11th-century embroidered cloth that depicts the Norman conquest of England in 1066. Halley's Comet did make an appearance in 1066, which is believed to be depicted in the tapestry as a bad omen for the English.
Halley's Comet is a Short Period Comet. It is actually the brightest known short period comet, one of the main reasons for it's popularity. It is visible from Earth once every 75–76 years. The last being in 1986 and the next being in 2061.
That is Halley's comet, named after English astronomer Edmond Halley,
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.
Halley's Comet is a periodic comet that orbits the Sun approximately every 76 years. Its last perihelion, or closest approach to the Sun, occurred in 1986, and it is expected to return in 2061. The revolution of Halley's Comet around the Sun is influenced by gravitational interactions with other celestial bodies, which can slightly alter its orbital path and timing. It is one of the most famous comets due to its visibility from Earth and its historical appearances recorded by various civilizations.
While this question theoretically has an answer, we don't know what it is, and no one is particularly interested in finding out. There are lots of very long period comets with multi-thousand or even million year orbits.
There is Halley's comet, and a meteorite crater called Hoba Iron Meteorite. Does that help?
No. That is totally unrelated.
Comets are ephemeral, though a few recur with a regular period. Halleys Comet is the classic example of this. Some comets have return periods considered greater than, or comparable with the age of the universe. Many are bound within the Solar System, with one of their orbital foci near the Sun, and the other in their region of origin. A Comet consists of a body containing evaporable material - ice or gas - and depending upon how close to the Sun they pass, they will eventually lose most of their mass. The comet's tail points away from the Sun, and is made from the volatile components evaporated by the Solar Wind or by particles from the Sun.
5'4" is the biggest one and the smallest one is 3'3"
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.
