Which comet takes the longest to orbit the Sun? What is the longest-period comet we know about? As far as the longest period comets go, the current leaders are Comet Hyakutake with an orbital period of 70,000 years, Comet C/2006 P1 with an orbital period of about 92,000 years and Comet West with an orbital period of about 250,000 years.

Short-period Comets Short-period Comets A comet with an orbital period of less than 200 years is known as a short-period comet or a ‘periodic comet’. These are now divided into Jupiter-family comets with periods less than 20 years and orbits that do not extend much beyond Jupiter, and Halley-type comets with periods of 20–200 years and highly inclined orbits.

more questions Comet Halley has a semimajor axis of 17.9 AU. (b)Find its perihelion and aphelion distances. Does Halley’s Comet spend most of its time near its perihelion distance, near its aphelion distance, or halfway in between? Explain. Solution: We are told that Halley’s comet has an eccentricity of 0.97 and in part (a), we calculated its semimajor axis to be 17.9 AU: perihelion distance = (17:9 AU) (1 0:97) = 0:537 AU

Comet Hale-Bopp The path that Hale Bopp takes can also be seen.. Because Hale-Bopp was discovered when it was so far away from Earth, there was a great deal of anticipation that when it got closer, it would be very bright. Halley's Comet, which last visited in 1986, has a nucleus of 20km.The nucleus of Hale Bopp is 40km, much larger than most comets.he comet would have last been visible 4,200 years ago. The reason its next visit is sooner than its last visit is because in March 1997, Comet Hale-Bopp passed within the gravitational influence of Jupiter, shortening the length of time it takes to complete an orbit.

The Origin of Comets Figure 160: Nucleus of Halley’s Comet. When this most famous of all comets last swung by the Sun in 1986, five spacecraft approached it. From a distance of a few hundred miles, Giotto, a European Space Agency spacecraft, took six pictures of Halley’s black, 9 x 5 x 5 mile, potato-shaped nucleus.

Hubble Sees an Asteroid with Six Comet-like Tails Tweet. Nov. 7, 2013: Astronomers viewing our solar system's asteroid belt with NASA's Hubble Space Telescope have seen for the first time an asteroid with six comet-like tails of dust. Designated P/2013 P5, the asteroid resembles a rotating lawn sprinkler.his NASA Hubble Space Telescope set of images reveals a never-before-seen set of six comet-like tails radiating from a body in the asteroid belt, designated P/2013 P5.

Halley's Comet This feature is not available right now. Please try again later. Halley's Comet or Comet Halley (officially designated 1P/Halley) is the most famous of the periodic comets, and is visible from Earth every 75 to 76 years.uring its 1986 apparition, Halley's Comet became the first to be observed in detail by spacecraft, providing the first observational data on the construction of the comet nucleus and the mechanism of tail formation.

- Venus is the second planet from the Sun, orbiting it every 224.7 Earth days.[12] It has the longest rotation period (243 days) of any planet in the Solar System and rotates in the opposite direction to most other planets. It has no natural satellites. It is named after the Roman goddess of love and beauty.

Comet Jupiter-family comets and long-period comets appear to follow very different fading laws. The JFCs are active over a lifetime of about 10,000 years or ~1,000 orbits whereas long-period comets fade much faster. Only 10% of the long-period comets survive more than 50 passages to small perihelion and only 1% of them survive more than 2,000 passages. Eventually most of the volatile material contained in a comet nucleus evaporates, and the comet becomes a small, dark, inert lump of rock or rubble that can resemble an asteroid.

What Planet Has the Longest Year? As the furthest orbiting planet in the Solar System, Neptune has the longest year, taking 164.8 Earth years to complete a single orbit of the Sun. Prior to its reclassification as a dwarf planet in 2006, Pluto was the planet with the longest year, equal to about 248 Earth years. Keep Learning.

Comet Halley The average period of Halley's orbit is 76 years but you cannot calculate the dates of its reappearances by simply subtracting multiples of 76 years from 1986. The gravitational pull of the major planets alters the orbital period from revolution to revolution.

Which planet takes the longest to orbit the sun? Quick Answer. Neptune has the longest orbital period of any planet within the solar system. The eighth and most distant planet from the sun, it takes Neptune approximately 165 years to complete a single orbit. It has an elliptical orbit with an average distance from the Sun of 2.8 billion miles, approximately 30 times more distant than the Earth. This distance makes Neptune invisible to the naked eye from the surface of Earth.

Comets, the Kuiper Belt and the Oort Cloud The short-period comets are thought to originate in the Kuiper Belt, an area outside Neptune's orbit (from about 30 to 50 AU) that has many icy comet-like objects. The long-period comets tend to have orbits that are randomly oriented, and not necessarily anywhere near the ecliptic.

Hale-Bopp Comet Facts View full size image. Hale-Bopp was an unusually bright comet that swung near Earth in the late 1990s, reaching its closest approach to the planet in 1997. It was most spectacular in the Northern Hemisphere and visible to the naked eye for about 18 months.Hale-Bopp was probably one of the most viewed comets in history.By comparison, the sun is 93 million miles, or 150 million km, from Earth). Astronomers still had the Hyakutake comet fresh in their minds at the time as the previous one passed by in 1996. Hale-Bopp was many times farther away than Hyakutake, but still appeared much brighter.

Halley's Comet: Facts About the Most Famous Comet Halley's Comet is arguably the most famous comet. It is a periodic comet and returns to Earth's vicinity about every 75 years, making it possible for a human to see it twice in his or her lifetime. The last time it was here was in 1986, and it is projected to return in 2061.

Comets Pluto---Home. Comets, unlike most small objects in our solar system, have been known since ancient times. There are Chinese records of Halleys Comet dating all the way back to 240 B.C. Halleys Comet is also depicted on the famous Bayeux Tapestry, which illustrates the French conquest of England in A.D. 1066.

Halley's Comet: Facts About the Most Famous Comet The comet's pass in 1910 was particularly spectacular, as the comet flew by about 13.9 million miles (22.4 million kilometers) from Earth, which is about 1/15 the distance between Earth and the Sun. On that occasion, Halley's was captured on camera for the first time.
