A comet's orbit around the Sun is pretty predictable, but its appearance depends on the structure of the ice and rocks below the surface, and we do not know these things. As the ice begins to melt, the structure of the comet and the distribution of frozen gasses can cause the comet to appear a little different each day.

∙ 14y agoHalley's Comet is currently just a little past the orbit of Neptune, and is moving fairly slowly toward its aphelion, or most distant point from the Sun.
On December 9, 2023 Halley's Comet will reach aphelion at a distance of 35.1 AU, or 35.1 times farther away from the Sun than the Earth is.

Halley's Comet, officially designated 1P/Halley and also referred to as Comet Halley after Edmond Halley, is a comet that can 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.

∙ 15y agoIt's difficult to say how close Halley's Comet will come to the Sun during the expected 2061 pass; we can't even be certain that it will return in 2061 rather than a few months earlier or later.
The reason is that there is a LOT that we do not know about Halley's Comet, or in fact, about comets in general. How massive is it? Were there any gassy jets escaping the the nucleus during the last pass? Exactly what was its velocity leaving the inner solar system? What massive bodies in the Kuiper Belt beyond Neptune and Pluto might it come close to? Will it collide with something else out there, and never again come back to the inner solar system? These are unknowns at the moment.

∙ 14y agoHalley's Comet is generally visible from Earth for a few months, every 76 years. The precise timing of the approach is important; sometimes, the comet is on the far side of the solar system and isn't especially visible, while sometimes the comet comes close enough to Earth to be spectacular.

Mark Twain was born in the year of Halleys' Comet, and said he would probably go out with it too. He did.

Yes it will not hit earth but it will come close enough to give us a scare.

Which part of the comet exists when the comet is close to the sun and also when it is far from the sun?
The nucleus is the bulk of the comet, this is present all the time until it eventually breaks up after many orbits. close to the sun, it gives of two tails as the sun heats the comets surface. Far from the sun it would just look like a rock that also contains a high proportion of ice.
When is the next halleys comment due to pass the earth?
We expect the only Halley's Comet there is to return to the inner solar system in 2061. That means it'll get close enough to the sun so that we can see it, but we can't tell yet exactly how close to earth it's likely to get.
Comet which seen in every 73 years?
That is Halley's comet, named after English astronomer Edmond Halley,
What are the chunks of ice and dust that orbit the sun?
A comet. ^.^
What is Difference between comet and Halley's comet?
Because it is one of the best known comets in the world.Comet Hale-Bopp (formally designated C/1995 O1) was arguably the most widely observed comet of the twentieth century, and one of the brightest seen for many decades. It was visible to the naked eye for a record 18 months.
How far away is Halley's comet from the sun?
Halley's Comet is currently a little beyond the orbit of Neptune.
What does the halleys comet revolve around?
Around the earth and past the sun.
Is halleys comet part of the solar system?
Yes. Halley's Comet is a comet that orbits our sun, and the definition of "Part of the solar system" is 'Any object that orbits our sun.'
Is halleys comet a star?
No. It's a comet.
What did Edmund Halley invent?
he found halleys comet he found halleys comet
What is Halley's comet nicknamed?
whats halleys comet nicknames
Why does Halleys comet travel through our solar system regularly?
Halley's comet is in orbit round the sun. Its orbit time is about 75 years, but as the orbital path is long and narrow, most of that is spent far out where we cannot see it. We see it for a few months when it is near the sun.
Does Halleys comet orbits earth in an elongated ellipse?
The Orbit of Comet Halley is an elongate ellipse, yes, but it does not orbit earth - it orbits the sun.
Why does halleys comet appear?
Halley's comet appears because it is a comet that orbits the Sun. It as a highly elliptical (oval) orbit which makes it seem to fly out of the solar system and back.
What size is halleys Comet?
big
What comet comes around every year?
I definitely know its not halleys comet
What year will Halleys comet come?
early 2062
