exists and is an alternate of .

The comet has a changing velocity, from around 1 km sec at aphelion to 100 km/sec or more when it is closest to the Sun. The speed estimated as it passed Earth's orbit in 1910 was 70 km/sec (254,016 km/h or 157,838 mph).

Like everything else in space, Halley's Comet follows an elliptical orbit. When it is closest to the Sun, it is moving fastest, and when farthest away, it is moving quite slowly. Right now, Halley's Comet is out beyond the orbit of Neptune, moving slowly and slowing down even more as it climbs away from the Sun. In about 10 years, it will reach aphelion, at which time it will be almost completely stopped relative to its distance from the Sun, and then it will begin the long fall into the inner solar system.

How old is Halley's comet?

Halley's Comet, if it is a typical comet, was created during or shortly after the formation of the solar system, some 4.6 billion years ago. Although it may have originally had a very elliptical (long-period) orbit, the current (short-period) orbit may have been established between 10,000 and 200,00 (MORE)

It takes Halley's Comet 74 to 76 earth years to complete an orbit of the Sun. It can be influenced by passing the large outer planets, so its revolutions are not always the same duration.

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.

What does the name Halley's comet means?

Halley's Comet had been recorded every 76 years or so since about 200 BC; Edmund Halley was the first person to realize that the comets of 1531, 1607 and 1682 were in fact the SAME comet coming back again and again, and he predicted that the comet would again be visible in 1758. Edmund Halley himsel (MORE)

When will we next see Halley's comet?

Halley's comet visits every 75 to 76 years. The last visit was in 1986, but just like every thing in the solar system, its orbit is a little eccentric which means it can actually vary from anything up to 74 to 79 years. The medium is taken at 75 to 76, so the estimated time of the next visit is 2061 (MORE)

What is the average speed of Halley's Comet?

The speed of Halley's Comet varies considerably, because its orbit is so elongated. At its farthest point in its orbit, it is travelling less than 1 km/sec (3600 km/hr). When it is nearest the Sun, it is closer to 100 km/sec (360000 km/hr). The often-quoted speed of 150,000 miles an hour refers to i (MORE)

What is the speed of Halley's Comet when it is nearest Earth?

The elongated orbit of Halley's Comet means that it has considerable velocity relative to the Earth and the Sun when it makes its closest approaches.
