Comet Halley last visited the inner solar system in 1986.

Halley’s Comet. The very name of this giant ball of dust and gas is enough to remind anyone over 40 wistfully what happened 35 years ago this week when the comet was the oldest and most famous observed us most visited.

If you saw Halley’s Comet in 1986 as a kid, there’s a good chance you’ll see it again in your lifetime — and you can’t tell that about any other comet with the naked eye.

Comet reached Halley on February 9, 1986perihelion- closest to the Sun during a brief journey into the interior of the Solar System and between the orbits of Mercury and Venus – before disappearing into the depths of the Solar System.

So where is it now? And when will it come back?

What is Halley’s Comet?

Officially known as 1P/Haley, it is an intermediate comet that has been around since at least 240 BC. It has been sighted every 75 years, although it was not discovered until 1705howBright objects continued to return to the night sky. That’s about 9 miles x 5 miles / 15 km x 8 km; Halley’s Comet is a big deal.

When will Halley’s come back?

Comet Halley has a highly elliptical orbit around the Sun and will return to the inner Solar System in 40 yearsperihelionon July 28, 2061. It is said to be much brighter than 1986 because Earth will be closer to the comet.

We know this because it returns to the solar system every 75.3 years on average, although it can vary between 74 and 79 years because the gravity of Jupiter and Saturn can change its orbit.

However somecalculationthat its close approaches to Jupiter and Venus in the future will mean that Comet Halley will eventually be ejected entirely from the solar system…perhaps to become an interstellar planet‘Oumuamua. Others suggest it could have vaporized or collided with something within 25,000 years.

Why is his appearance in 1986 so important?

Mainly because we could see up close. Or at least the scientific community already does. While millions of school projects, hundreds of TV documentaries, and miles of press coverage have made possible a return for Halley’s Comet, it’s not really easy to spot. A lot of people were still alive thenthinkYou saw it, but it’s only slightly brighter than Polaris, the North Star.

Far more significant than any cursory visual observations in 1986 were the amazing close-up images taken by the European Space Agency’s (ESA) Giotto spacecraft, one of several research vehicles, of Comet Halley in 1986.

On March 13 and 14, 1986, it approached Comet Halley to within 373 miles/600 km and spotted the comet’s nucleus, jets of gas and dust as it passed its tail, and detected complex organic matter in a comaga around its nucleus.

It’s been an impressive few months for space fans; On January 24, 1986 – just as Comet Halley was closest to the sun – NASA’s Voyager 2 spacecraft passed througha fly from Uranusto give humanity the first and only glimpse of the planet “Bull’s Eye”. However, that was forgotten just 4 days after NASA’s space shuttleThe challengerexploded shortly after takeoff.

Where is Halley’s Comet now?

Go outside just after dark and look for Orion’s Belt in the southeastern night sky. Now look down the horizon to find the very bright star Sirius. Comet Halley is currently a little further east near bright star Procyon.

That’s its place in the night sky, but of course Halley’s Comet isn’t that far from any of the stars. It is in the so-calledKuiper belt, solar system outside the orbits of Neptune and Pluto. It is currently 35 Astronomical Units (AU) from the Sun, about the same distance from the Sunreverie– And the same distance from the sun as Pluto.

An AU is 35 times the Earth-Sun distance, about 93 million miles/150 million kilometers, which astronomers use to describe the size of the solar system.

Why is Halley’s Comet so popular?

Because of what the British astronomer Edmond Halley deduced from it. He reckons that the “great comet,” which continues to be seen every 75 years, is actually the same object. Aware of “great comet” sightings in 1531 and 1607, he saw the comet that would later bear his name in 1682, orbited it in 1705, and predicted that it would orbit in 1758. That is correct, although he died by then and it was actually the last few days of 1758 before it was observed.

Astronomy has introduced a new class of objects orbiting the sun, and historians are no longer able to pinpoint the exact dates of historical sightings of a “great comet.”

So Comet Halley must be the “comet” recorded by Chinese astronomersShiji onMay 25, 240 BC BC – is now considered the first recorded sighting of Halley’s Comet.

As can be seen later this year fragments of Halley’s Comet

Every year in early May and late October, the Earth moves through the streams of particles left in the Solar System by Halley’s Comet since its last flyby in 1986.

The Eta Aquariids are a meteor shower that lasts from April 19 to around May 28, peaking on May 5 each year and producing around 55 “meteorites” per hour.

From October 2nd to November 7th the Orionids meteor shower takes place, although its peak occurs on November 21st/22nd. October is when viewers can see about 20 “meteorites” every hour after midnight.

I wish you clear skies and open eyes.

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. Many comets with long orbital periods may appear brighter and more spectacular, but Halley is the only short-period comet that is clearly visible to the naked eye, and thus, the only naked-eye comet that might appear twice in a human lifetime. During its returns to the inner solar system, it has been observed by astronomers since at least 240 BC, but it was only recognized as a periodic comet in the 18th century when its orbit was computed by English astronomer Edmond Halley, after whom it is named. Halley’s Comet last appeared in the inner Solar System in 1986 and will next appear in mid-2061.

During 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. These observations supported a number of longstanding hypotheses about comet construction, particularly Fred Whipple’s “dirty snowball” model, but also provided data which substantially reformed and reconfigured these ideas.
