Halley's Comet begins its return journey to Earth today

This view of Comet Halley's nucleus was obtained by the Giotto spacecraft as it passed within 600 km of the comet nucleus on March 13, 1986.

After zooming away from Earth for nearly 40 years, Halley's Comet is about to turn tail and head back our way — setting the stage for a spectacular close-up in 2061.
On Saturday, Dec. 9, the famous comet is predicted to reach its farthest point from the sun, also known as its aphelion, at a distance of about 35 astronomical units (AU) — or about 35 times the distance between Earth and the sun, according to NASA. That puts the comet well beyond the orbit of Neptune, and nearly in the front yard of Pluto, which orbits at about 39 AU.
In a sense, this is the midway point of Halley's routine, 76-year orbit of the sun. For the last 38 years or so, the comet has moved millions of miles farther away from us every day; now, it will spend the next 38 years moving closer.
Halley's last close approach of the sun (or its perihelion) was on Feb. 9, 1986, when it swooped to within 54.6 million miles (87.8 million km) of the sun, according to NASA; that's about 0.58 AU from the our home star, or just interior to the orbit of Venus. Astronomers haven't seen the comet at all since 2003, after which it became too small and dim to see.

Halley's Comet makes its next close approach to the sun on July 28, 2061. Until then, you can experience the "hairy star's" shimmering legacy twice a year, during two meteor showers associated with icy debris left behind by the comet on prior trips across Earth's orbit. The Delta Aquariid meteor shower in May and the Orionid meteor shower in October both occur when old debris from Halley's Comet falls through Earth's atmosphere, burning up as "shooting stars."

Breaking: Halley’s Comet changes journey plans from Earth to Mars because of the shitshow going on here right now.

I was in 7th grade in 1986 and I remember discussing it. I Probably won't be around in 2061 but still pretty cool.

In 1986 I was in the backyard with my dad watching for it. I was 8. He told me it would be 70 something years but it would be back again. I remember telling him “wow. I’ll be old then. You’ll be REALLY old!” He said “yeah I guess I will be!”
Seeing it come around again would be a pretty cool bookend for me. Hopefully I’m around to see it.

How could you know that I lived in a desperate world?
How could you dream that we were all made out of stone?
What is the truth, what is the faithful lasting proof?
What is the central theme to this everlasting spoof?

I remember Hale Bopp in the 90s. It was phenomenal to watch over the course of several nights.

My grandmother got to see it twice. Once when she was a little girl and the other 3 years before she died at the age of 96.
She told me that when she was a child people thought the comet was going to hit the earth and they were going to die.

So, how many football fields is that, you know because (as an American), I can only gauge distance in football fields comparatively?

I would be 98, I don't think I'm going to make it. I do remember it being around in 86 though
