Will Halley's comet still be around when the sun becomes a red giant?
The short answer is No, Halley's Comet will not 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 would have sublimated out of existence long before then.

What is the part of a planet or comets orbit where it is closet to the sun?
That point is called perihelion and its position can be defined by longitude and latitude in coordinates based on the ecliptic (the Sun's apparent path through the sky). The longitude of perihelion is one of the elements that define the object's orbit.

What did general relativity predict about the orbit of Mercury?
The orbits of planets have a point called the "perihelion", which is the point where the planet is closest to the sun. Over time, the perihelion of Mercury's orbit changes position, orbit around the sun itself. General relatively correctly predicted that the shift in the perihelion of Mercury's orbit is much faster than is predicted using Newton's laws.
Where does Halley's Comet spend most of its time?
Halley's Comet spends most of its time in the outer regions of the solar system, specifically in the Kuiper Belt and the Oort Cloud. It has an elongated orbit that takes about 76 years to complete, bringing it close to the Sun and Earth during its perihelion. During its long journey, it remains far from the inner solar system for the majority of its orbit.
A comet near the sun whose orbit is elliptical would never be near the sun again?
A comet with an elliptical orbit will periodically come close to the sun at its closest point (perihelion) and then move away to its farthest point (aphelion). So, a comet with an elliptical orbit would indeed come near the sun again after moving away. The exact timing of when it would be close to the sun again depends on the specifics of its orbit.
When was Time of the Comet created?
Time of the Comet was created in 2008.
What is the duration of Time of the Comet?
The duration of Time of the Comet is 1.73 hours.
What was the date of the last time earth was at perihelion?
January 3, 2010 was the date of the "most recent" perihelion. Hopefully, not the "last" one.
When is halleys comet coming again?
It can be seen every 75-76 years. The next predicted perihelion of Halley's Comet will be 28 July 2061.
What is the current position of Halley's comet?
Comet Halley is currently still sailing away from the Sun and most of the planets in our solar system as it makes its way to its aphelion (farthest point from the Sun) in 2024, out around the orbit of Pluto. It was last closest to the Sun in 1986, and will return to perihelion (closest to the Sun) in 2061.
