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.
Halley'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.
From Wikipedia, the free encyclopedia
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.
Scientists aren't exactly sure how far Comet Hale-Bopp is from the sun at any one point, but they do know it is millions of miles. The distance is so great that it takes this comet about 2,400 years to complete one orbit of the sun, a trip the Earth makes every year.
It'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.
Halley's Comet doesn't orbit the Earth; it orbits the Sun. It is in a highly elliptical orbit that takes it out beyond the orbit of Neptune, and comes just inside the orbit of Venus, taking 76 years to complete one orbit.
Halley'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.
It has never hit the earth - otherwise it would have ceased to exist. It comes round in a cycle about every 75 years.
Mark Twain was born in the year of Halleys' Comet, and said he would probably go out with it too. He did.
Halley's Comet has a period of 76 years, and is expected back in 2061.
Halley's Comet will not strike the Earth.
Yes it will not hit earth but it will come close enough to give us a scare.
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.
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.
That is Halley's comet, named after English astronomer Edmond Halley,
A 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.
Halley's Comet is currently a little beyond the orbit of Neptune.
Around the earth and past the sun.
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.'
No. It's a comet.
he found halleys comet he found halleys comet
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.
whats halleys comet nicknames
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.
The Orbit of Comet Halley is an elongate ellipse, yes, but it does not orbit earth - it orbits the sun.
big
I definitely know its not halleys comet
early 2062
