The short answer: No, Halley's Comet will not still be around when the Sun becomes a red giant. When a comet gets close to the Sun (formally called a perihelion passage), the comet's surface gets heated up, and a layer on the surface sublimates and is lost into space. This means that a comet gets smaller over time, since it loses mass each time it swings by the Sun. As a general rule, a comet whose perihelion is one AU (the same as the average Earth-Sun distance) will lose about one meter of its surface during each perihelion passage. Comets that get closer to the Sun than 1.0 AU may lose several meters of their surface during each perihelion passage. Halley's comet is currently on an orbit with a perihelion of 0.59 AU, so it probably loses several meters from its surface during each perihelion passage. The average diameter of Halley's Comet is about eleven kilometers, so after a few thousand more perihelion passages, none of it will remain. Each orbit of Halley's Comet takes about 75 years, so it will be completely gone within a few hundred thousand years, at most. The Sun will become a red giant in about five billion years, so Halley's Comet have sublimated out of existence long before then.
What else can I help you with?
When did Halley's comet most recently pass around the sun?
Halley's Comet is still orbiting the Sun. It was close to Earth in 1986.
What did Edmund Halley discover?
Halley was an astronomer, mathematician, and general scientist, and is best known for his prediction of the return period of the eponymous comet, Halleys Comet. Edmund Halley discovered the motion of stars.
Is Halley's comet still forming?
no

What is comet elenin?
It is supposed to be an "average" comet, but there is much speculation as to whether or not this is true. The mass of the object is still in question, and that helps promote the idea that it may not be a comet.
Haley's comet is what kind of comet?
No. Comet brightness depends on the actual brightness, but also on the distance from the Sun. In 1986, Halley's Comet was not very bright, because it was far from Earth. The previous appearance in 1910 was distinctly brighter, but still wasn't even the brightest comet of the year; the "Great Daylight Comet of 1910" was visible during the day!
Can a comet still be extremely white with just a coma?
NO.
When did Frank Asch die?
Frank Asch, children's book author is still alive and well and writing children's books. Check out his latest book entitled: The Daily Comet: Boy Saves Earth from Giant Octopus.
Will halleys comet kill us in July 28th 2061?
No it won't. It will be seen from Earth, but it will be a long way from Earth, so it poses no danger to us. You can see many things in the sky at night that are a very long way away. Right now Halley's Comet is too far away to see, but when it is close enough to see, it will still be a very long way from Earth in 2061, just like it was when it was seen in 1986 and in 1910 and other previous occasions that it has been seen from Earth.
how much does halley's comet weigh in pounds?
Comet Halley still weighs over a hundred trillion pounds! iqos-heets.ae
When will Shoemaker Levy will pass by earth?
The famous Shoemaker-Levy 9 won't be passing this way again. Jupiter swallowed it back in 1994, striking the Jovian giant's back side. When the planet swung around so we could see, it's surface was still roiling from the event. Quite spectacular.
What company owns comet?
Comet cleaner is owned by Prestige Brands. It was originally owned by Procter and Gamble, but was sold to Prestige Brands in 2001. Proctor and Gamble still owns the rights in Europe, and the industrial Comet cleaners.
